What all is needed to do a 4l60e to th400 swap from start to finish and what is the price range to do this? Also what are the names of some good shops that have some th400 trannys for sale? thank you for the help

Ijust did the swap in a 98 t/a from a 6 speed. I just took a used th 400 and took it to a tranny shop an had them put a reverse manual valve body and a high performance clutch kit in it. That total caost was around 700 for very beefy tranny. The converter i got was TCI anywhere from 300-600$. You have to order a spacer from GM that cost 60$ that goes on after the flywheeland then the flywheel bolts go on. The flywheel I used was a 4l60e flywheel. You have to make the converter bolt holes on the flywheel a little bigger. Then I had a heavy duty drive shaft madeor you can buy them made already. I used a pro ratchet shifter under the stock shifter boot. I am interested in getting rid of my set-up. I only have about 400 street miles and only 7 1/4 mile passes on the complete set-up. If you have any more questions or are interseted in my set-up let me know.

 

were did you get the th-400?

 

Friend had a pile of trannys in his garage. Otherwise junk yard usally sell cores that need rebuilt. Or TCI sell a nice for around 900$. Or Cone sell a simaler one for 750-850.

 

thanks alot!
