6L80E questions
I just picked up a 17,000 mile 6L80E from my insurance company out of a 2007 2wd Sierra. It's going into my 1981 GMC someday but I've got some questions that so far I haven't found answers on here for.
1. What yoke does the trans need? I'm unsure what yoke I'll need to run and the trans didn't come with one. I'm supposing my best bet is to order one from GM for the truck the trans came from and have a new driveshaft built with 3/4 ton u-joints. But if I do that, how am I going to mate it to the 12 bolt rear? 2. I picked up an ECM (PCM) from them as well. They said that it mounted near the battery on the donor truck. But I've read on the net that the ECM is internal in the trans. Anyone confirm that there should be an external or internal ECM? Thanks.
