anyone have a list or link to what cars the th400 came in? i need a new tranny and i want to get away from the 200r for a little while.
 
anything with a big block up until the last of the BOP big block cars were built in the mid 70's. up until the late 70's sometime they used a weaker version that looks like a TH400 in passenger cars. i can't remember how to tell the difference, tho. i think they were called a "TH375" or something like that.
 
th375 has the same slip yoke as the th350 200 4l60e 700
th400 is larger same as 4l80e
 
There are two TH-375s: the TH-375 or TH-375A, and the TH-375B. The TH-375A is the more common, medium duty version of the TH-400. The TH-375B is a less common, heavy duty version of the TH-350. Used in certain full size Buicks in the mid 70's.
A longshaft TH-375A is like a longshaft TH-400, but it uses the smaller diameter yoke from the TH-350. Pan shape is that of the TH-400. The only difference is the output shaft and the tailshaft housing. The TH-375A has the guts of a TH-400 with the output shaft of a TH-350. It was used in full size cars, and it effectively shortened the drive shaft. The TH-375A is also often swapped into big cars as a direct replacement for dead longshaft TH-350s.
On the underside of the trans, right where the tail housing bolts up, the letters "TH-375" can usually be found cast into the trans housing.
The TH-375B pan is the same shape and size as the TH-350.
