The th400 is a much stronger transmission meant for heavy duty use while the th350 is meant for normal use.
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.
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.
A 350 has a vacuum modulator back at the tailshaft on the passenger side. Also the pan's shape is different.
Powerglide, Th350, Th400, or a muncie 4 speed.
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.
That is the wire that actuates the kick down solenoid. The th400 has an electric kick down solenoid and no cable like the th350
Powerglide, TH350, TH375, TH400, TH2004R, TH700R4, 4L60E, 4L80E
Yes a th 400 can be bolted to a 350 also a th350 and a power glide
Buick Olds th400 or th425 (front drive) or dual pattern case th350
Th350 has a modulator on the back. Th400 has modulator on side. 700R4 has no modulator.
yes as long as it has the correct stall that you need and its not from a 350C lock up.
