The alison 1000 trans is an 5 speed auto i believe correct if im wrong. They use it in the heavy duty trucks and the gear ratios are as follows. A 3.10:1 1st, 1.81:1 2nd, 1.41:1 3rd, 1:1 4th, and .7:1 overdrive fifth gear. I hear the alisons are very strong and with those gear ratio ratios it pretty close to a 700r4 but with another gear so is there any way you can bolt one of these up to an older small block im sure id have to mess with a bunch of computer stuff but other than that any one know if its possible and if it is what it takes to do it.

You would never be able to fit it into a third gen. The truck tranny is huge.
