What is the difference between the 350 and 400 when making the switch from the 200?
With the TH350 the same Driveshaft will work.
With the TH400 the same Crossmember will work.
You'll need one of these for either Trans. Check valve for the Modulator.
hello; In my past I had a turbo 350 and the 400 trans was what people had upgraded too. In the 350 I lost high gear so a rebuild had to be done and that's that. But everyone put shift kits and a larger pan and drove. But with the TB why would you want it? The OD is nice for the MPG so I guess they fail more so people go to the older tried and true models. Maybe when the power of the TB gets up there they fail.
