the th350 pan is more of a defined square shape with a corner cut off and the rear of the case is basically smooth.
the th400 has more an undefined and not square pan with ribs or fins at the rear of the case.
The th400 is a much stronger transmission meant for heavy duty use while the th350 is meant for normal use.
Powerglide, Th350, Th400, or a muncie 4 speed.
no , look for a 200r4 trans which has overdrive and the same lenghth as the th350Wow...completely wrong answer. The 200-4R is the same length as the TH400. Not the TH350. The 700-R4 is the same length as the TH350. And yes....a B.O.P. TH400 will fit that 403 just fine. You'll have to locate a transmission cross member for the TH400 if it was originally a TH350.
Buick Olds th400 or th425 (front drive) or dual pattern case th350
Automatics would include th350, th400, or the 700r4, if you want a overdrive.
just about any Chevy trans, a TH350 or a TH400 are the most common and will both fit. as far as engines and transmissions with Chevy's there just about all interchangeable without to much messing around. only difference with a TH350 to a TH400 is that a 400 will take higher horsepower/torque. but for most stock applications a TH350 will be fine , oh and the TH400's are slightly longer to.
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.
sure it will fit, as long as they are the same type, th350 or th400. also 2wd 0r 4wd.
That is the wire that actuates the kick down solenoid. The th400 has an electric kick down solenoid and no cable like the th350
A 1980 Cutlass Supreme could have come with either any one of these Turbo-Hydramatic transmissions: TH200C, TH350, TH350C, TH375, or TH400
they are not maintenance adjustable on the th400
