If stock G.M. transmissions are rated by torque, 4L60e and 4L80e, then why does the aftermarket rate them by horsepower not torque?

I think its because people have a better hand on understanding HP but its just for general ratings to give people and idea of what the are looking for a range

I don't think I would worry too much about that when choosing a unit or combination for my car. There really is no rhyme or reason for it.

Unless you are making well in excess of 700 H/P most of the stock trannies can be built to take that much energy.

Kinda reminds me why we build "Stage" or "Level" so and so .... I do it for comparisons sake. But, I do not necessarily agree with it. It has been that way for many years in the aftermarket. What I tell guys is this.... you wouldn't ask your engine builder for his "Stage" 2 engine right?

Most of the units we build are custom builds that are specific for the application.

Like said its a general guide line, Mnay times we may not get to talk to a customer before they order but trust me if we think they ordered wrong we give them a call ,
