Superior shift kit?
I know because I've used a few.
It really depends on what transmission you're putting it in.
For a th400 I would only use a TransGo.
For a 4L60 I would only use transgo.
For a 4L60E I might try something else but used transgo.
Superior has been around for a long time as Fairbanks.
They seem to be about half the price of other brands.
not only do you get a full manual v.b. they also have awesome customer support and you get a new tcc valve that does not pusle on engagement - very important if you are apllying tcc at the track.
