Sorry I did a search on shift kits but did not find anything really good.

I'm going to have my turbo 400 rebuilt and was wondering what shift kit would be best for me.

I will be driving the car street only.

Thanks, Joe

We use the Transgo High Performance shift kits here. They come with a new set of direct clutch release springs, a HD snap ring for the case to retain the intermediate clutches and a fully adjustable shift program with good instructions. The Transgo kit retains most of the stock components where most other kits will have you disable accumulators, block off passages and leave out check balls. We've found the resulting "window shattering" shifts to be extremely hard on the internals. The Transgo kits, when correctly installed provide firm/smooth shifts at light throttle and very firm shifts at heavy/full throttle.....Cliff

The transgo shift kits are a good choice. I too use them in the transmissions I rebuild.

Thanks again for the info....Joe

Ditto for the Transgo kits.
Some years back, I bought a combined TCI rebuild + shift kit for a 727 Torqueflite. The instructions were photo copies, hard to read & see where particular springs & balls were supposed to go. As I read through these photocopied instructions, I thought they looked familiar. Hmm? I got out the left over instructions from a B&M kit years earlier & guess what? The TCI instructions were an almost word-for-word copy. Odd word changed here & there, some paragraphs rearranged, but copied. So I wouldn't trust anything TCI tells you.
