Where do you find a 4L80E??? Thanks...
3/4 and 1 ton GM trucks from '91-on. These trannys (because all of their shifts are controlled electronically) need a stand alone computer for $800, or the whole ECM from the donor truck. It's the closest thing you're going to get to "bulletproof" in factory GM stuff. It's basically an overdrive TH400 that's electronically controlled.
