The front pump's job is to fill the converter with fluid. It provides the pressure necessary to engage gears. You don't have to "pre-fill" a converter.
Its like packing bearings, you could get a Masters from Harvard or Standford on it and make a UA-cam video and people will say you are doing it wrong, some people that are master mechanics absolutely positively swear on filling a converter before running it and some dont,that will never change. like a car battery on the floor,ive had a few old timers when i was younger yell at me "Get that battery of the floor!!!!", that has been debunked thanks to the internet, another one that blew my mind was the crankshaft thing,i have read extensively that in reality you dont have to stand a crank on its end but heck i still do, reason a lot of people do is because it saves space not because it will warp,anyhow, i just think its interesting all the different ways of doing things people have.
@@BLACKEDOUTVIK No need. Like the OP said the pump will fill the converter. There's enough assembly lube in the converter for initial start up. 43 years in transmissions and I have never prefilled a converter and never had a problem.
easier way is to just spin the converter with the trans standing on end, and it will seat itself while spinning. should drop 2-3 times while spinning to reach the fully seated position.
I have 2015 mdx with 145k miles with a bad torque converter. Car shudders between 40mph and 60mph. Should i change the converter now or keep driving like that and rebuild the transmission later? Since the labor is about the same?🤔🤔🤔
Is there a way to confirm damage to the front pump if bolted up without being fully seated? I realized my error and dropped it. Removed the TC and reinserted it and it all seems fine but if I can confirm its ok without disassembling the trans, that would be ideal.
I know this is a old comment but it sounds like you lucked out,if something had happened you would know it in minutes,once the pump is crushed by the converter etc you will have a major fluid leak and some "strange noises" if you start the car
@@dntlss I re-installed everything and drove it 4 miles and my fuel pump gave out. Have had it parked since last fall getting the rest of the suburban together. There is a solid puddle of trans fluid from the bell housing area. It was leaking this bad before I rebuilt it as well. So not entirely sure what the issue is but it’ll have to come back out soon enough. 1996 4L80 on what I did.
I think more emphasis on the importance of the placement of the Flywheel should have been addressed. The bellhousing is properly aligned with the centerline of the crank shaft and the flywheel is against the crankshaft (parallel to crank shaft flange). If the flywheel is not properly aligned you'll end up with all the same issues again. In order to get a proper alignment with little runout, I think it's the most important part of beginning the entire installation of the torque converter and will make the install that much easier when you move onto the Bellhousing alignment.
I didn't talk about clutch pressure plate and flywheel alignment because this was a video on properly installing a torque converter in a transmission. The converter gets bolted to a flex plate not a flywheel so i didn't include flywheel info in the video.
I have 2003 DODGE RAM VAN with 46RE. I just finished rebuilding the transmission and installed the new torque converter. After I seated the torq converter completely in it measured 5/8" from housing to bolt. However the torque converter only turns 2" to the right or left. I thought it was supposed to spin freely. Did I do something wrong? Please help.
@@askcramer500 thank you for your reply. I removed the torque converter and tried to turn the shaft with plyers but only the smaller diameter shaft turns but the larger one doesn't. Thank you for your assistance.
Hi, my Ford Expedition with the 6R80 transmission has thrown a PO741 torque converter clutch stuck off for a while now. The transmission shifts good and doesn’t slip or jerk but runs slightly higher RPM than before on the highway. The rebuild price I was quoted of $4,000 is not an option. Could I replace the Torque converter and do a fluid and filter change?
My 1999 Eddie Bauer 4 l shoc , the engine races but the suv moves off only slowly. After a few seconds and picking up speed then it quick in pick up. What should I check?
How do you know if you have a bad torque converter or if it's even a torque converter in there when you drive cause I'm purchasing a car for dirt cheap with a new trans just don't know about the converter ?
Does it just sit in the flywheel anyway? I just installed a transmission and when I let off the gas my RPMs drop to idle and I have to hold the gas till the rpms catch back up
Shouldn't my axle input gears or whatever (the place with the seals where you plug in the axles) shouldn't those gears inside spin if the transmission torque converter is seated properly? I was thinking they would spin as I move the torque converter, but maybe I'm wrong. Thanks for the video!
My dodge charger 2011 has no transmission in the vehicle or battery when I had it towed. I wasn't able to get the car in park and I had the tow man just drag it on the flatbed. Now the car is still in park but if I push it I can get it to roll like it's in neutral. What do you think I broke?
@@askcramer500 thank you we're in a process of taking a motor out and didn't really want to mess with the torque converter except for the four bolts in the flex plant ,can the converter be left on the transmission for an extended time without support ?
@@dissociativecat7495 yup leave the converter in the transmission. after you unbolt it push it back into the trans as far as it will go maybe 1/8" and good luck pulling the motor. get a jack under the trans to support so it doesn't go nose down after the engine is separated
Depends on the engine and what you go with. For this Chrysler trans, a 5.2 magnum/LA block is internally balanced and a 5.9 magnum/LA block is externally. Look up engine specs to see which is what on any make engine and how they’re balanced vs what part is used to balance.
make a mark on flex plate and transmission and converter before you remove it ,if you have not moved the shafts or pump in any rotation it will go back in easy , do the same thing with the flex plate before it comes off
Thank you, I'm doing this soon. But - I have a pretty good trans fluid leak just streaming out, when the engine is running, coming from the flexplate cover area. I have the 4T65E out and don't see any problem with the torque converter, torque converter seal or the o-ring on the input shaft. But the pump shaft seems very loose. End play is 1.7 mm and the shaft can be easily pushed to one side or the other of the input shaft that surrounds it. The shaft can be easily rotated in either direction. Do you think it's possible that replacing the shaft could cure the leak? If not, Is there something else fairly simple I could look at? Thanks for any advice y'all can offer.
I have a 2007 Ford f 150 , just had tranny rebuilt and I’m feeling gears shift up and down with a kick/bang and getting on highway I feel no power , feels like it takes longer to get up to 65 but once there it drives ok also I’m getting a shake at idle and a knocking noise , didn’t have the noise prior to rebuild . The guy who fixed it says the tranny says it’s all normal that he used stronger more powerful parts so that’s what I feel and the loss of power is a pause in overdrive so I don’t go to fast ! Am I wrong to think that’s insane ? Can the wrong stall torque converter cause these issues or a transmission rebuilt the wrong way ?
Excessive side load on the input shaft from misalignment of the engine gearbox. (Transmission input shaft and engine crank Causes 1st gear shift issues, poor shifting, clutch wear, pilot and bushing noise and engine problems. The misalignment and all that happens as a result of the misalignment causes clutches and gears to wear out. The input shaft bears the damage and the splines on it wear.
Installed a Torque Converter on and now having issue with the car not shifting into 4th gear. Fluids are in the correct measurements. Do you know what could the problem be?
Automatic trans, But I have a 2011 Cammed Dodge Charger R/T FTI 3200 Stall. The reason why I changed it is because after I installed the Cam the car lost a lot of low end power.
Yes, but it should go normally to 4th gear. I drive with Manuel (plus/minus) thing lol so it won't try to go on fourth and something messes up. So i am not sure if the shift points changed.
Zeyad H. sorry I'm not much help my rule is "if it worked before I fixed it, what did I touch/change. check everything you touched if there are no problems start looking at what has changed now that you are running a different can and converter. What motor do you have? what can did you put in it? did you have it tuned after the cam install?
The front pump's job is to fill the converter with fluid. It provides the pressure necessary to engage gears. You don't have to "pre-fill" a converter.
Hey man my transmission dosent go into reverse. Reverse lights come on and it just rolls. Anu suggestions? Also im leakin fluid from between my bell housing and engine. How do i stop the leak?
Sam Weems your reverse band or reverse servo is probably burned up. You could do an oil pressure test of the reverse servo first but you will probably need to remove the pan and valve body to inspect.
I've got a question. I have a 97 cherokee drive train. I jack up the rear axle, the wheels spin. I put it on the ground, I get nothing. I have changed the transfer case, made no difference. Is it more likely the torque converter or the transmission as a whole?
kyle edington hi Kyle, make sure your transfer case is not in neutral and it sounds like a transmission but not the torque converter. Does it have reverse?
Gaona Gaona you may short circuit the positive terminal on the starter when you remove it. That's the most obvious danger after that probably just set a bunch of dtc s / codes. I suppose there is an outside chance of doing damage to a module, tcm but I seriously doubt it.
Michael Cramer the mechanic did the job make a mistake and now i put on parking and turn it off and remove the keys and the truck still running and set it to reverse and then i can turned off and it starts even if i set on P/R/D/1/2 .
I have a rebuilt transmission that we have been in twice, with a 3500 stall an a 406 sbc. the car engages in gear it's moves like 2 feet an the back wheels lock up instantly going fwd an reverse an then just starts revving the engine. all fluids are fine. is this a sign of torque converter problems?
Got a Saab 9-7x with a Chevy 5.3l and 4L60E. Started making a pulsing, clattery, vibrating sound when put in gear, now it's progressed to a constant clunky sound. Still pulls and shifts fine.Could the TC be going out, broken flywheel, or something else? (it drove from out of state for about 4 hours making that sound, so reasonably sure it's not a rod bearing)
Now i know why my THM350 crashed 30 years ago... i did not go for the second clock or click whatever ....i rocked the converter till the first clock and good to go. WRONG .... .......There was no internet so was difficult to get the info .....
