TH350 to 2004r swap

[v8440]

Hi all,


I've searched the transmission topics for this info and not found it, so here goes: I have a car with a short shaft th350, and I have a pretty well built 2004r that I want to replace it with. What must I do to accomplish this? Specifically, do I have to shorten or lengthen the driveshaft, where is the transmission mount point compared to the th350, and is the spline count the same on the 2 output shafts? If it matters, I have an aftermarket B&M ratchet shifter in this car, so I'd imagine the shifter won't be a problem.

The 200-4R is a good replacement for the 350. The overall length and output splines are the same which means no driveshaft mods. The crossmember mount will need to be relocated back about 6 5/8".

As for the lock-up, a simple kit such as the TCI 376600 will provide for convenient, hands-free operation of the TCC. It works off a fourth gear pressure switch and a vacuum switch. [/QUOTE]

If you do a little more "key word" searching I'm sure there is more posted on her.
