Who is a quality manufacturer of tranny rebuild kits?

Are you referring to performance or factory

Rebuilding a stock transmission whether it's AT or MT. I am not talking about track-only performance tranny, although I'd love to hear about those also, especially if you're talking putting performance kit into a stock tranny.

well, I am in the process of rebuilding a honda automatic transmission thats slipping. I was looking into many different kits (factory spec) and ended up buying from WIT overhaul kit with steels and raybestos frictions. After calling a few places, it looks like the only difference amongs same kits are the frictions, OE seem to be the most expensive. I am trying out the rays and see how it'll work, might try borg warner next time just to see if it'll be any different.
