I don't know anything about other trannys. If you go to the PA web site, you will see the various trannys they sell. The SuperComp is the beefiest version and includes the manual transbrake valve body. You can get the SuperComp in the AOD version or the 4R70W, which is what I got. I think for pure drag racing, there may be some that are better, but for a street/strip car, I think this is a good choice. It's relatively expensive though.
