I am in the process of gathering parts for a aod - t5 swap. I have a tranny that needs to be rebuilt. It grinds from first to second i was told and eveything else is ok. I was wondering what rebuild kit to buy. There is a master and regular im guessing. I see both on ebay and ddperformance has one for 150 so im guessing its a master. Which do i need? Should i tear it down first to find out? Im gonna get the video b4 i start tearing it apart tho thanks
