Hey guys who here is running a performabuilt tranny. I've heard nothing but good things about this company and I want to know what you guys think about them

I plan on buying one of their transmissions when I finish upgrading my motor.

 

the parts used for all transmissions are pretty much universal. it's the builder/combo that is used that is important, because different cars/people need different things. Transmissions aren't a one fits all thing.
the options provided by performa I haven't checked into that much, I seem to hear more buzz for pro built/dana, and have looked at some of the combo's of parts used and seems sound.
