Alex, it is my understanding that the CD4E, like all automatic transmissions, are electronically controlled. This is why my friends father has an automatic in his 1970 Camaro, so he doesn't have to worry about mis-shifting down the track.
And as for the shifttronic helping. Of course it will help a little, if you use it correctly. It would of course work much much better if you were to couple it with a tranny cooler (should definately do anyway), torque convertor, and a oil cooler (someone correct me about this one, there's probably another name for it, but right now at 3 am, I can't think of it). As far as I understand the having a shiftronic capable transmission allows the driver, you in this case, quasi-manually shift gears at whenever you want. They will downshift automatically when you slow down, but won't upshift until you do it manually.
This would probably help you out down the track a little, but wouldn't do much at all (if anything truthfully) without that torque convertor.
I hope I've answered this good enough for you, and for everyone else, if my information is incorrect, and/or can be added on/subtracted from let him know. I know I was eager to learn when I first joined, only I just read and didn't post.
I was a quiet one...:stupid:
