Yes it will.. But You need to have a flywheel with two sets of bolt holes, 3 holes with a diameter 1 inch different pattern from the other 3. Atotal of 6 holes. The 350 converter has a higher stall than a 400, about 2/3 hundred. Because the 350 is smaller in diameter. It will work just fine.....!
A 350 or 400 torque converter will not work on a Powerglide transmission due to differences in design. All are somewhat similar but come in different sizes and connections.
Automatic transmissions lose acceleration driving uphill because of the torque converter. The engine turns one side of the torque converter and the other side is splined into the input set of the planetary gears. The torque converter uses fluid to turn the input shaft in the transmission. When the transmission is locked into gear and going uphill the torque converter has to work against power losses from the tires on the road and when the engine is working harder the torque converter cuts or "shears" the fluid and it causes the transmission to overheat. Always make sure you have enough fluid in the transmission
major job for the inexperienced you must first remove the transmission then you remove torque converter from flex plate. flex plate is equivalent to a fly wheel in a standard gear box to replace torque converter, is another job in itself as it must be installed loosely until transmission is installed , then properly filled with transmission fluid then tightened properly if not sure about all this, it is likely to not work or fail going down the road WAIT!, ..unbolt the torque converter from the flex plate and remove with the transmission! If you pull the transmission separately, you risk damaging the pump in the transmission! Same applies going back in, the torque converter needs to be meshed into the front pump of the transmission before putting into the car. Then once the transmission is bolted to the engine, THEN you bolt the torque converter to the flex plate. If you do as described in the first answer, you will very likely end up replacing the entire transmission! This job requires experience and special tools, not for the beginner.
Sorry but it will not I have tried. The 400 is too wide and it won't bolt up correctly when the transmission is installed.
Take it to your favorite garage and let a pro perform the work.
Well, the question is hard to answer, but here is a shot: Yes, it is working when the transmission is in park, because it is still providing enough input to run the pump to provide pressure for the hydraulics in the transmission. The torque converter operates off of input from the engine, not the transmission, so it will build pressure, this is why when you rev up the engine and then drop the transmission into a drive gear, the car will jump.
depends upon auto/manual, but suspect improper torque converter, or bad throw-out bearing installation.
No.
YES As long as the flexplate is the same size or has additional mounting holes. To add to this answer in depth. i changed from a 350 to a 454. the 454 had a th400 transmission and the 350 had a th350 transmission. (This was a 4x4 so we had to use the th350 transmission because it had a married transfer case)the th400 flywheel did NOT match the th350 torque converter. We installed the th400 converter and it fit perfect in the th350 transmission. I would make sure torque converter bolts to flywheel and as well fits into trasmission before attempting to install in vehicle. It is a huge pain to make the swap half way through the install.
Yes
Assuming this is an automatic transmission, you didn't install the torque converter all the way back into the transmission. If you put any amount of pressure trying to mate the two by drawing in on the bellhousing bolts, you have probably damaged the front pump in the transmission. Take the transmission back out and try to work the converter back into the trans all the way by rotating and wiggling the converter. If the converter doesn't drop back all the way, take the trans to a shop for repair.
try a bottle or rear end friction modifer if the problem is torque converter shudder it sould quit in a matter of miles most people mistake torque converter shudder for a eng miss feels the same
