Hi. Excellent wealth of knowledge you have. Just for anyone who came to take a look at this Video, there is a Hidden Drain Plug in the transmission near the side cover. Its an 11mm socket (i think) that should get you the rest of the fluid, minus what in the torque converter and radiator. Source: Cadillacforums
TCC :Torque clutch Solenoid is also a common problem. Mine melted around the connector on the solenoid. which is located under side cover... no fun to get to... The TCC basically does over drive gear range.
Sounds like a problem in the valve body if there is no slippage and it always starts in 3rd. This is accessible from the transmission pan underneath so it shouldn't cost a huge amount to get it fixed. If you want to tackle it yourself there are some good diagrams available for free. Google scribd 4t80e, and you'll find a GM manual with exploded view diagrams, for example. Disclaimer: I've never serviced a transmission valve body.
I just recently found you on UA-cam and subscribed to your channel and I enjoy your videos. You are so logical and speak so clearly that it seems like everything is rehearsed but I'm sure it isn't. I am retired and worked for many years for a research and development company that manufactured gas turbine engines. I worked in the engineering group And met many guys just like you. What do you do for a living? Thanks for spending the time to record and post these videos.
Thank you for your comment! I actually started doing this because I hate being on camera... Most videos are not rehearsed so it helps to be able to cut and edit! And you are astute, yes, I am in engineering.
Had p0741 i think on a 2000 eldo and sold it to a shop that had the expertise to service and sell this beauty. Shop owner , cert. Cadillac master tech said the channel plate gasket is most common problem for the tcc to shut down as it is designed to do to prevent a trans overheat and further damage Just bought a 1999 esc and has no codes no coolant loss and only a couple minor issues. I love these cars and they are a dying breed.
Yep, these are very nice vehicles compared to much of the junk being sold these last few years. I guess I got spoiled by the reliability of some of the vehicles that were available over the last 15 years, but with most of the newer ones out there these Northstars seem like pretty pretty solid units by today's standards.
hello, do you know if the transmission cone ,by the vehicle speed sensor (pass. side) can be rebuilt without a total overhaul ,just replaced the cv axle and diagnosed the problem was from the trans tail..thanks .
I'm not a fan of full transmission flushes either. You will never have an issue with a transmission if you take all the fluid out by dropping the pan multiple times. My fiancée has a 2003 Mercury Sable with 197k on the original transmission fluid, the fluid was black but not burned I did 3 pan drops and filter changes over the course of 2 months and she doesn't even have transmission issues. Mind you she's driving it over a year already with no issues. You won't have an issue, just check the dipstick before you change it and make a judgement based on the condition of the fluid, not the mileage. Good job I loved your video
This vehicle is now being driven by a relative. The TCC still doesn't work as that was a mechanical issue unrelated to the fluid but otherwise it is still going strong! Glad that worked out for you on the Sable - once the fluid is that far gone you never know how it will take new fluid.
@@knurlgnar24 You're definately right, and I was skeptical about doing a fluid change too, but I did a few pan drops every few weeks cause I wanted the new fluid to clean up the internals of the transmission before I changed it again. I was surprised after the 3rd fluid and filter change, I step on the fas and it shifts smoothly through all the gears and it doesn't slip. We really got lucky with that
I just bought the same make and model car but mine is a 2001. When I bought the car the service engine soon light was on and I got the codes read. I have the same torque converter issue. I'm not sure if its the torque converter itself or if its the torque converter clutch. I'm assuming its the clutch. What parts do I need to purchase to replace the clutch? Is it an easy fix? I also have a Mass air flow sensor code, any advice on that would be nice. Thanks.
If u remove the scavenging filters u can can alittle more fluid out then put back on and under the driverside filter theres a 11mm bolt that as a additional 3 quarts that will drain if u remove the bolt but u must remove the filter to see it
A MAF code definitely warrants a repair for performance, economy, and longevity reasons. It should be an easy fix that you can probably do with a junkyard part. The torque converter clutch unfortunately requires the entire transmission to be removed in order to repair properly, so you're pretty well stuck with the transmission as it is. The internal seal that usually leaks causing this code is not critical so the vehicle likely has significant life left, you'll just lose some fuel economy.
2003 sts models were made with special part numbers which make it impossible to find any parts at a junkyard no cars are inchangable with the 2003 models trust me I went to jumkyard and tried to get a bunch of parts foe my 2003 pulled them off a 2003 sts but all the parts were diffrent it pissed me off thats when i found that they made special part numbers for these models hahaha
@@tonevaldez9568 While I find that hard to believe automakers have done these things before so I wouldn't put it past them. I gave this 2003 to a family member a number of years ago and it is still running reliably today. And you're right about that drain bolt in the transmission. I didn't read about that until later. Oh well, in my case the fluid was fine so it didn't really matter. And thanks for not making another comment about changing the filter like many others have! It's not in the pickup strainer assembly like in most transmissions.
How did you do with the car. Im sure it became a problem as it got older. I have a 2004 with 300,000 and it was a horrible car to this mileage with repairs I did as a mechanic. Always till this day feel bad about people who own this car.
Never once had a problem with it in the 6 years I owned it after fixing it up post purchase. It now is problem-free in the hands of a relative who perhaps doesn't treat it as gently as I did..
@@knurlgnar24 Good to hear. For myself I traveled Highway miles 300 per week to go to work. I did everything to baby this car every 3 thousand miles mobil 1 synthetic oil and filter changes . Always new air filters , and cleaned the throttle body etc etc . After 100,000 miles that when one thing after another started to happen engine codes , manifold bolts pushed out had to but a tap and retap, you name it. All the genetic problems listed on the forum I saw. TCC selnoid in the transmission etc etc etc. I fixed the problems but it was a constant project and it took a lot of time away from everything elso on the weekend. Be well and thanks for responding.
If your torque converter clutch throws a code p0741? , try clearing code. My 99 eldo( no its not a wreck, its one of the cleanest eldos youll ever see) throws this code, i erase it with the a/c control panel, and it functions perfectly for another 6 months, its common for these higher mileage cars.
@@knurlgnar24 I'm going to exchange the transaxle fluid in my DTS next week. RIght now I have to deal with a broken Stud that holds the pulley tensioner of the water pump pulley. Will need to mig/mag it to get the stud out.
This is not a solenoid issue, but a bearing seal issue causing insufficient apply pressure and is a well documented problem on these transmissions that requires a transmission replacement. The solenoids rarely fail though they are often blamed. Also, the TCC solenoid in these vehicles requires the K frame to be dropped in order to access the side cover on the transmission in order to replace it if that were the problem.
hey I have a 96 deville ,,. also are the same engines in yours being a Seville...mine a deville?? .77280 2200 is what I paid gold clean acouple dings but nice..
As i understand you did not drain 100% of fluid from AT. Probably it went with Dextron 3 from the factory. You added Dextron 6. The question - is it compatable with Dextron 3 while it remained in your AT.
@@knurlgnar24 i just did mine tonight it drained out 11 1/2 quarts . but now i have to figure out what going on because that hidden plug was already removed...so i need to find out the issues this might create...already drove couple 1000 miles since i bought it so....
failsafe mode is 2nd gear so you likely have a mechanical problem. (Do check the wiring harness first, though) Google 'scribd 34140243' for a troubleshooting manual. pp36 seems to have relevant info. BTW, are there any DTCs that may help point to the issue? I wish I could help you more but I've never serviced a valve body. Let me know how it turns out if you would!
That's an interesting strategy but it would seem to me there would be little difference. Once the pan is drained there's little difference and by just dropping the pan I can skip the siphon/pump step entirely.

How many miles was your car when u change the fluid
this video was a big help!! thank you for taking the time bro. doin big things!!

You forgot to remove drain plug of side pan. Did you read the manual?
There is no 'side pan'. There is a torque converter drain bolt however which I did not remove.
@knurlgnar24 11mm socket to remove drain plug located after angled filter is removed (this will drain side of transmission not the torque converter)
THANKS A LOT FOR THE VIDEO..
why wouldn't you change the transmission filter
is this an sts?

I couldn't find the transaxle drain plug either.
i have a 1992 cadilliac. sts 4.9 what is my transmission call because my car it want move when i put it in gear plus it smokes what is that
Your car has the 4T60E transmission.
There’s another screw near the filter, once you unscrew it more transaxle fluid will come out.
I've gotten this comment a lot over the years and found out shortly after I did this service. Wish I knew this info at the time!

DexronIV is backwards compatible and far superior than DexronIII.
theres a drain plug for the side tank under the screen ...
Yup. I found that out later. That would have helped get more of the fluid out each time.

Siphon from the fill hole first for less mess!!!!

You should suck out the liquid first throw the dipstick tube, the job is less messy
