i know how much everyone loves these kind of posts, but i'm going to do it anyway
looking to see if anyone may be interested in a trade, my T5z setup for your 4R70W setup, everything to do the swap. it would have to be a local or semi local deal. you can drive my car to see that everything works as it should, and i'd want to drive yours also.
as I said, i'm not 100% sure I want to do it, but close.
if anyone is interested pm me and we can talk. John
