Re: T176 for GM swap
I will second all those post stearing you away from the t176. I have one in my 84 and looking to swap since it needs a rebuild with about 200k on it. If you are doing rock crawling and drive your jeep on the pavement. Once you go to low gears the over drive is a must. I am keeping my AMC 258 so the playing field is wide open for me since I will probably have to adapt anything I decide on. Again you might want to consider overdrive which I believe the 4500 has not sure which other GMs do.
