Identifying a 400 vs a 350
well I was told by the original owner that I had a TH400 but after getting Ron Sessions book I don't think I do. Can anyone tell me how to identify what trans I have?
Thanks for any help. Ken

A turbo 400 has the vac modulator mounted on the pass side front of trans,,,a turbo 350 has it mounted on the rear pass side of trans. Also a turbo 400 oil pan is anything but square/retangle.

Here you go.
 The 350 is a good tranny, and onless you are pushing gobs of h/p or torque, you should stick with it. THe 400 is bullitproof, but eats power. Some claim as little as 15 horses, others say as much as 30. Either way, 15 is enough to feel it in the seat. ------------------ '69 G.M.C. 350/350.

th350 is good unless you have a 350+ hp engine unless you super build the th350 for the higher horse use
th350 is very tough, nothing to worry about if you take care of it, its more reliable than stock 700r4 and thm200 and thm2004r and etc etc |
