well my trans has been missing 2nd and 4th gear for almost a year now. it doesnt bother me too bad other than it is my winter beater and winter is coming quickly so i will be driving it everyday. i guess my question is, can i swap to a chevy th350 without any issues (or for that matter a th400)? what would need swapped, wiring or computer issues? the truck is a 93 with the 4.3l and a 700r4 i believe. i have a th400 laying here at the shop that i know is in good shape and can have a th350 easily as well. i dont want to sink a ton of money into this truck so cheap is good.
