Hi, I'm not new to this site, but just became a member! I've gotten a lot of good info from here, I'm currently installing a 6.0/4L80E into an '86 Silvy and you guys have been a ton of knowledge. I started it a couple of weeks ago, but still working out the bugs and drove it out of the shop last night. Got to get it to the muffler shop so I can get on the road!!!!
