These various transmission videos have prompted me to keep an eye on the coloration of my vehicle's fluids, not just the mileage on the odometer.
I've long know that oil should not be super black (in gasoline engines) but now I also know brake fluid is supposed to be nearly clear, transmission fluid should (typically) red and translucent, and radiator fluid should not be cloudy.
This will help me know when to get fluid exchanges done BEFORE problems arise, and in the case of radiator fluid, to know when problems are happening. Nobody wants the forbidden milkshake!
Don't forget about the filter especially if they had never REGULARLY service the transmission. Most of the heartache comes from lack of service until it's too late.
Not a mechanic but I used to do PC repair and the same applies. The moment you touch it everything wrong with it is now your responsibility even if it had the issue when it came in the door. Always do a comprehensive troubleshoot and document EVERYTHING OR get it in writing that you're only taking responsibility for the specific issue needing repair. And be fully prepared to fire your customer. IMHO.
Lol , same with plumbing and boilers .
Oh yeah.
Friend: Hey I just got a new router and I can't connect to it, can you help me?
You: Yeah, OK (Likely all he needs is to enter the correct WiFi password - AND SPELL IT CORRECTLY).
Friend: Hey thanks man...
Friend (The next day): Hey, now I can't print. I don't know what you did yesterday but my printer has stopped working! Get over here because I have to have this report submitted by yesterday.
@@georgewaring7168 And the colours on my monitor are all wonky! WHAT DID YOU DO!?
😒
20y ago at the Allison Transmission course, they warned against fluid changes on under-maintained high-mileage transmissions. The gunk and debris that had accumulated at the bottom of the pain could disperse in the fresh fluid, potentially making its way into the valve body, where it could partially block a valve, leading to inadequate pressure on a clutch/clutches, resulting in a slipping transmission.
I did a partial fluid swap and filter on my 08 lucerne. I also changed the trans. pan to one with a drain plug. First time I had ever worked on a transmission. I was so proud. Then I went to clean up and noticed the magnet still sitting in the old pan.
Get a magnetic drain plug.
Thanks Ray. I get lots of folks who don't want regular transmission services but want the fluid changed after the transmission seems to have failed. Stupid is FOREVER (Ron White)
I'm a 71 year old female and I understand your explanation. Thanks for the clarification l.😊
Tay, Thank you for addressing the myth of new fluid ruining a transmission. My favorite retort to something being seized "You froze it up with too much oil, eh?"
When I was young, I replaced a lot of friends' transmission with used units. Every single one received a fluid exchange as part of the sway. None ever failed.
Thanks for the transmission transmission over and out😎
I serviced my wife's transmission fluid at about 110k miles on a 2010 Ford focus. There were no issues before... and there seems to be no issues now at about 15k miles later.. From what I remember I just had the shop dump the pan and replace the filter. So far so good.
Exactly Right!
People don't go Way past the service due Then one day wake up and think. Oh I think I'll get my transmission flushed today. They noticed something for weeks, months then yesterday it seemed worse but went away. Better hurry and get it flushed. And then days weeks later the transmission goes away. Must of been the flush.
RainMan you are correct. Nothing can help a worn out high mileage transmission
Great video Ray... Very clear the rational behind it.
You are correct. Just for context, I am the person who clued you in about the miss-placed snap ring on the 6L80 from a week ago. Servicing of transmissions is very over rated. They are not open to the atmosphere so do not collect dirt and the filter will not plug.. In my opinion, the oil will last for 1 - 2 hundred thousand miles or more. A proper pressurized transmission does not slip if it is sized properly for the power level and conditions it operates under. Heat is the big enemy. I have had several vehicles over the years that I did not service the trans and they all went a long distance. One 1989 GMC pickup had 425,000 on a 4L60. The only reason I did service on my latest vehicle is it was a condition of the warranty. If there are particles or pieces in the oil, it has been slipping or a hard part is failing. Servicing will not change this.
You are WAY more polite to trolls than me. That’s my biggest problem, no filters. Guess I’ll just change my name to Lucky Strike. Lol
Thanks for your opinion on that subject, Ray, i appreciate it
You will always get the armchair mechanic, who reads a service manual and they think they know it all. Im a sparky and I have the same problem, they read something online and they think they know all about being an electrician, I have a 300 page book of wiring regs I have to comply with plus serval large books of various building codes I have to abide by , there is a reason why I spent 5 years training and going to college. Because I right there wrong, plus every year I have to keep up with the changes which cost me an arm a leg . One book can cost me about $220 a year imagine the cost if several books of regs change, and sometimes a change in regs can cost me serval thousand of dollars if I have to buy new testing equipment if regs change. So for get the haters and the pipe and slippers mechanics there not worth the effort in a response
outstanding video Ray
Facts! Been down that rabbit hole!
IMO a 400k transmission has more than paid for its keep & if it's acting up, replacement is the way to go.
I used to be... Back in the day. TH 350 etc... You could change the Filter and fluid and it would correct itself.
You're right Ray 👍👍
Great point!
This is all about risk and who wears the consequences if something goes wrong. Those who have commented saying they have flushed high mileage units and not had a problem, that's fine. But ask all the auto trans specialists (in any country) who repair/service this stuff day after day and see what they say. They will say what Ray has said. Also, if something goes wrong, who wears the liability, or in the least, has the stand-up arguments with the customer, when the customer says that it was running fine before you serviced it and now it is not. Ray has to run his shop; not run a back yard, help your friend, neighbour or whoever shop. He has to be insured, wear the liability and confront all the dramas, dramas he does not need. So totally agree with Ray's assessment. Too many miles; too much risk. I would not do a service on such a car even if the customer was willing to sign any disclaimer. Retired mechanic/machinist in Land Down Under.
@M used the words "I had"
Just because "you had" doesn't make it so. If it were scientifically proven that clutch dust prolonged the life of a worn out transmission, you could rest assured..., transmission fluid with added clutch dust for worn out transmissions would be readily available off the shelf.
One thing it does do, if you park the vehicle for a few weeks, is settle and make the valve body gum up - Happened to me on an old Ford C3 transmission, strip and a clean, and it was all good.
I'm not a mechanic, but I suspect the thing is that some transmissions, with certain faults or wear, can be made worse by changing fluids at high miles for the first time. It doesn't mean it will, but it's a possibility. Because the cost of a new trans is high and whoever did the fluids will be blamed, they may not want to take that risk even if it's small.
A Transmission can last a long time when property maintained chainging oil and filters will also alert you a more expensive problem round the corner. Precision Transmissions have a great Utube channel and they have a race car too.
Unless your vehicle has a 4L60e and then you’re just driving around on a ticking time bomb. 😂😂
Yea...we just pulled a transmission out of a jeep...you can already see where this is going but, service declined. Only fluid please. Took like a dozen pictures of the scrap metal and re installed it. Well, they only wanted a clutch kit so. That's why it came off to begin with.
Oh! There was another one that came back yesterday, another a tech strongly recommended new control arms. Service declined! Well, it had a wheel delete not even a week later and buried it straight up into the fender well lol
I once did a fluid flush on an S10 that had black transmission fluid. My boss warned the customer that the transmission could be on the way out, but he said it had been shifting fine, and to go ahead and flush it, and if the trans failed, the trans failed. I thought sure I'd have to run more than the usual amount of fluid through it to get it to come out clean, because there was zero red left in the old fluid. It looked water with black stuff mixed in. But 12 quarts was all it needed. I changed the oil in that truck for 2 more years before I left that shop, and the trans still worked perfectly.
My Mustang has well over 200k on it and the transmission started doing this shuddering thing, the car almost felt like it was going over the rumble strips. I wasn't about to have it flushed, but I did pump out all the fluid I could, drop the pan, put in a new filter and fresh fluid along with a tube of anti-shudder additive. The transmission is working just fine, but for the next couple of oil changes I'll pump out a quart of fluid and replace it with fresh.
We used to say , best way to service an automatic transmission is to rebuild or replace, changing fluid and filter at anything over 175,000 miles is a waste of fluid and filter.
Mind you most folks used to trade in their cars at the 80 to 95,,000 mile mark.
Common sense as always Ray.👏👏👏👏👏👌👌👌👌
Like changing the oil in a engine with a lower end knock, it doesn't fix anything. Keep up the good work, Ray, and don't beat yourself about trans work. Unless you have been trained in it, best to refer such work to others.
If you go in deep enough to take out the clutch plates, change the plates. It's cheaper than the labor to get at them again.
People are afraid of working on a transmission because "they work on magic."
Just a series of planetary gears and clutch sets with hydraulic control of which clutches are engaged. Inside the modern electronic controlled valve body is where you can mess up easiest and you can just order the rebuilt valve body.
I wish automatic transmissions had a drain plug and a spin on filter... That would point out the need for fluid changes, rather than sealing it up and making it appear to be something you don't touch for 150,000 miles. (which is about failure point with no fluid and filter service)
Sometimes, the grit in fluid helps a transmission to shift by providing friction. High mileage cars are horrible to work on because a simple fluid change can change the engine or transmission. Even a high mileage oil change going from standard to synthetic oil can cause leaks due to synthetic being thinner/less viscous at the same rating.
Thank You Ray.... Its sometimes hard to shine when those about you " Preach " doctrine that neither has correct content or reasonable fact.... but instead has information which has as many holes in truth as swiss cheese.... Keep up the good work.... Smile, Laugh and know We are 100 percent behind you.... Doc.
i always found it easier with a trans like that to just reseal and replace clutches if i already have it out, that way i only have to take it out and put it back once
I watch precision transmissions very interesting channel
I was taught what you dràin out you put right back in if possible. Like you said Ray, the old fluid contains clutch material among other things. New fluid could to the transmission slipping badly. Leave bad enough alone.😊
my nephew inherited a vehicle with 250k miles, fluid never changed. being a service writer did not help him the trans died shortly after the fluid exchange.
Old school thought was that if you service an A/T it will soon fail. Probably because it was already worn out. Old AT s had manually adjusted bands to take up for wear. Im sure there is a limit to wear compensation.
i have to agree
i did a tranny service a while back on a good ol mercury and it failed
car had 177,627 miles on the clock and failed because the car never had regular maintenance
I have experience the same situation personally people would come in and want a flush test drive the vehicle before I would and find transmission would slip, or bang into the next gear or not want to shift at all I tell the service writer they get all mad I will not flush it
Total agree
I had this issue with a mechanic, he did not want to change the fluid on my 1988 Eldorado even when I told him the trans was replaced 150,00 miles with a new one.
That's what puts you in the "Professional Technician" category Mr. Rainman. Easy to pick the low hanging fruit... much more work to actually do the repair. I've always heard returning customers are what makes a business successful, so no doubt you will be. Now the real question is how do we clone you and your all your staff so I don't have to drive 2,712 miles if I need service.
First off, you don't really owe an explanation for the choices that you make as mechanic at your own shop. Second of all, I don't think you're bagging on high mileage transmissions. The bottom line is that a transmission or engine will only live for a certain amount of time depending on quality of build, and upkeep. Some are better than others; but at the end of the day, the cost to repair becomes economically unfeasible. As far as the 400k mile comment, newer vehicles are built flimsier and cheaper every year, and secondly, there are tons of people out there that still believe in no service transmissions for the life of the vehicle. There are also people who just beat the crap out of their cars and expect them to keep going indefinitely.
Keep doing what you're doing Ray, love the content.
Mabey we could ask project farm to test the theory that replacement of bad fluid may cause slipping with new fluid senerio.
Most customers wait until the transmission is broken to get the fluid serviced. "The fluid change broke my transmission"
I wish I could figure out my 2000 awd V8 explorer issue. It has a stumble in 2nd gear under acceleration. It almost feels like the awd is locked in constantly.
Notice 2 weeks after changing the awd transfer case fluid with mercron 5. Only stumbles in 2nd . If I ease on it, don't feel it. Floor it, don't feel it. Has a 4W70? Type transmission
Hey Ray
If there is no issue, changing the fluid is fine. If there is an issue and you want it fixed, you end up with a fluid exchange as well. People hardly ever seem to replace any fluid other than engine oil (washer fluid doesn't count).
Yep. Acura dealer won’t do an exchange anymore. They made up some excuse that was probably a lie but the bottom line was probably just this. They do t want to get blamed for “ ruining” the transmission. I’m not worried, 17 year young. Runs perfect, looks nearly new. Xmission serviced every 30k.
Hi from uk ray 👋👍 totally understandable 👌 about time you rejected working on the super scrap bagged mini i experienced a set of tappets/lifters on vauxhall i think your ecotec chevy ish engine near to this but had 300 +miles and was hard session between last service but ( i know the car and laddo) so anyway i look after his cars for years did quick service oil and filter etc and within 5 mins of car running was like someone just took oil cap off and dropped load 10 mm nuts in rocker box 😂 but was due tbh well looked after car still goes just he got engine i fitted in own time👌 talking engines project rubesu? Never give a job both your knees just kneel gracefully and wuusaaaaaaaa 🧘♂️ thanks as always for your time ray be safe and see you soon 👍 👋
I knew a Mark Saunders here in the UK, I could swear he payed attention at school....
@DeepakKumar-lv4te that defo wasn't me then my friend am denser than water 🤣
Of course you should service in regular intervals but a broken transmission will not be fixed by exchanging fluids only.
Ray, my old cocker - I'D TRUST YOUR OPINON hand's down over any other grease monkey out there! Why? Because you sir, are an honest hard working man.
Actually, it's not really a myth or a rumor but something Scotty Kilmer preaches constantly because he's had that happen more than a few times. He's seen it time and again where they do a full fluid flush and shortly after, if the fluid's never been changed because it's supposedly a lifetime transmission or something, and then it would start slipping shortly after. He does however recommend it as a regular maintenance item where flushing the transmission is a good idea if done at regular service internals. But a high mileage transmission he just recommends a filter drop which is a third or less of the fluid as a whole to see if it helps or not as a first step. If that doesn't help fix the problem, he says then definitely take it to a mechanic because as you said, quite often the bandaid won't fix the problem, but if people want to try that first themselves, sometimes it helps but usually won't.
Please turn off Scotty. Or ask him a simple question. If engine oil is used up and burnt, is it best to leave it in there as the debris is what is keeping the engine alive? Of course he will say no. Well, trans fluid is oil. Worn out trans oil works exactly the same as worn out engine oil. Which is to say it doesn't work at all. Also, just like the engine, there is a filter that catches all the "helpful" debris and doesn't allow it to get to the clutches anyhow. So that is all a myth that people like scotty continue to perpetuate. The reality is that the myth exists to deny service with a plausible sounding explanation. This is because customers will try to claim a fluid exchange caused their failing transmission to fail. The average customer, if you explain what may or may not happen, will still blame the mechanic after their already failed transmission fails after a fluid exchange. So best to tell them the myth and they will come back after total failure of the transmission when you can charge big money and not have the grief of the customer. No car guy worth anything should believe this myth, nor Scotty.
@@paulnoble5627 How exactly is it a myth if it's actually happened to him on multiple occasions? Also, Ray isn't the end all be all, and Scotty has about twice as much experience as Ray. I'm not saying I listen to everything Scotty says as gospel and in fact take his advice with a grain of salt, and I do disagree with him on more than a few things. Also, that being said, I've also had that happen to me once on an older merc where I did a full flush and fill and it made things worse.
Ray or anyone here please comment ... I have a 90 Silverado 2500 with about 180K miles. It sports a 3-speed automatic transmission. I bought it when it had 140K miles. I cannot tell if it has ever had a transmission service (aka replace fluid and filter). I had a transmission service shop tell me to never do it because it would cause problems (ruin transmission). I have yet to do it because I just don't know enough about transmissions to make that kind of call. But it seems illogical to me for this to be the case.
I would appreciate some feedback on this. I need some direction. The transmission is currently not experiencing any problems to my knowledge.
What happen to the scubby-doo with a broken water pimp, broken bolt, broken drill, broken easy-out, broken motor and upset mechanic.......
my grandfather had a ford ranger. he never serviced the tranny except top it off if ever needed. it was around 180k miles? tranny was shifting funny so he took it in for filter and new fluid.
it never shifted by itself again. only way to get it to shift was manually changing the gears.
Well then, that settles it. You have established precident. The grandpa clause. Anyone that does not realize that fluid life is finite and that it needs to be replaced ( the time and mileage interval completely dependent on the conditions and manner in which it has been used) is an idiot.
You are right if high mileage Trans is ok don't change the fluid if you never had. No leaks leave it alone. Trans servicing is the most unused service there is. The newer front drive and fancy Trans are different than your 72 chevy
Sadly most people aren't smart enough to change their transmission fluid LONG before the milage gets high and do it on a regular basis....
OIL IS ALWAYS CHEAPER THAN PARTS....
Not a mechanic but have worked my my cars in the pass. Changing oil, plugs, wires and the basic other stuff even changed transmission fluid and filter. My question why do they want to flush my transmission instead of just changing to fluid and filter? Sounds like the automobile mechanics want to make more money.
A few years ago I was sitting in a bar sipping a cold one
The much younger bar gal was saying that her transmission was slipping and that she needed to put sawdust in it
Because that's what her dad did
I was JSMH.
Back in the '50s and '60s we occasionally saw a manual transmission with sawdust in it. This was a car dealer's trick to quiet a worn-out transmission long enough to get it sold. Worked like a charm until the bearings died. ONCE, we had a car towed in as undriveable because the owner heard about and tried the sawdust trick on his Hydra-matic. (Bar gal's dad?) A little knowledge is a dangerous thing!
👍👍👍👍👍👍👍👍
I agree if there is no issue and you have 200k then how would a fluid exchange change anything. If anything it would be beneficial. Again if the trans has no known issues and running as designed.
Thanks mate❤😂🎉😢😮😅😊
Howdy partner
Do you recommend a car with a transmission that is better than others, or is the easiest or cheapest repair if something was to go wrong?
yeah, a stick shift would be my opinion only, still do normal maintenance, and replace clutch only when necessary.
If people would do preventative maintenance on their transmission the darn thing would last a lot longer. Prevent the issue before it happens…
What changes actually take place in ATF as time & miles pass? "Burnt" fluid - is the fluid itself actually oxidized, or are overheated / burnt clutch faces etc shedding burned material into the fluid? Or both? Inquiring minds want to know!
That five times fast.
If it slips, clunks, jerks, squeels then leave it and give it back. I don't care if it's 100 miles or 300000 miles. If it drives good and shifts great, then change it, no problem. Done it many many times. Changing transmission fluid to fix mechanical problem is like erasing codes to fix the engind problem. 😂
I had fight with my Lexus dealership to do mine it has 85k miles
I got a question ! I just bought an 09 Avalanche and the car fax shows the last trans fluid change was at about 40k miles. Now im not sure if it has been done again since then since it doesnt show up on the carfax. Now my question is should i swap it at 150k or just ride it out?
I’d say , check the condition of the fluid.. get a small sample put a few drops on a white paper towel. If’s it’s not terribly dark and brown.. I’d say just do a filter and clean out the pan and fill it back up.
@@462ANIMAL cool but if it's extremely dark just leave it and save up for the inevitable?
@@etp_23 well , that’s up to you.. depends what you need the vehicle for. If you plan on towing stuff and travelling far from home, I’d still pull the pan and see what the magnet looks like.. a bit of sludge and no chunks is ok.. and you’d only be removing 6 litres or so.
@@462ANIMAL yeah I don't tow much and and don't usually travel much either lol I'm a home body i guess I'll check it out soon! I'm not driving it much right now I'm trying to sell off my ralliart before I drive this full time
Yeppers. You were the last to touch it so it's your fault lol
What's your opinion on CVT TRANSMISSIONS?????
I HATE MINE!!!!
I’ll never own one
You must realize that you are contradicting Scotty Kilmer on changing fluids in old transmissions. I'm going to make some popcorn and enjoy the show!
Hmmmm... I asked my mechanic to change my tx fluid @40k (100k recommended & done then) & he told me it wasn't necessary. I want it to last forever.
Should I insist?
Ray, was it confirmed that the 400,000 mile pickup was still on the original transmission?
That’s what he said
@@RainmanRayOffDutyor she said😂
You know, when i had older engines that were worn down i would just fill the crankcase up with misc metal scraps so as the oil flowed through them they could grab some not needed metal and deposit it in places like the cylinders where it was really worn.
Change of fluid every 40000 MI or you never change I super high mileage transmission the best thing is to drain the fluid change your filter filter the old flood and put it back in and always let the customer know this is not to fix this may create more damage change every 40,000 mi order don't change it
Good advise Ray, But didn't you die in a wreck yesterday?
I did 🤣🤣
@@RainmanRayOffDuty You're really not very good at this dying thing. Back to school for YOU!
Flush the automatic transmission every 37,000 miles and it will last 300,000 miles or more. When the transmission chops or slips, it is too late.
A band-aid doesn't work when you need open heart surgery.
i rather watch u making a bbq than comm on someones rant
That is not a myth I have seen lotsa automatic transmissions with high mileage and as soon as I change the fluid and it for the first time that's ever been changed usually within 100 miles of the transmission quit working
I'm not a mechanic, but I've never seen it.
I personally bought 2 cars with over 200k miles on the original trans fluid and I flushed both in my driveway (by disconnecting the cooler line) and they were smoother and kept lasting, even as I beat on the cars.
When I found out my dad never changed the fluid in his fusion at 140k I changed it for him (pan drops to use up 12qts) and it survived until 200k miles when he overheated the engine.
I would never hesitate to change high mileage trans fluid... If a fluid change "breaks" it, it was already broken.
@@volvo09yep! Agree!
Good reason to refuse service.
*Promo SM*
If you do service a transmission do not skimp on the filter or fluid, get the OEM or a high quality unit from a reputable supplier and OEM fluid. If you do have any issues later you will be glad you did not use the cheaper imported junk.
About to spend $300 having my fluid changed according to schedule. If it explodes after that the dealership can fight it out on who’s covering it, the 200k warranty I bought, or the mechanic that did something wrong.
Not to be bashful, but if you're coming at THE Infamous Ray for not wanting to perform something on a sketchy truck or car, you're that person that brings it to another guy to fix a non repairable problem. And probably goes karen when they explain the real problem.
One opinion that made sense to me was to just change the fluid on an old trans, rather than flushing it. The theory is that it would not be good to push a lot of dirty fluid through the parts all the sudden. But if you have been doing it every 25 or 30k miles it wouldn't be a problem. Not a pro, and definitely not a transmission mechanic.
