I heard (from a guy who seemed to be pretty knowledgeable with trannys) that the TH400 was a horsepower robbing transmission. I know the th400 is built to take a lot more horsepower, but he said if you're not putting out the horsepower- you're wasting it. It would be better with a Th350. He also claims that you can't do much with a 400 as far as shift kits go. Has anyone heard of this before? How does one transmission use horsepower?
Also, any advice on shift kits for the TH400. Mines got kind of a sloppy shift.

Your friend is incorrect.

Use a TransGo kit on the tranny.


www.bulkpart.com seems to have reasonable prices
