Re: LSx Swap build thread index!

This is my first LS1 swap. I'm looking for info on adapting a 4L80E (from a 2000 truck with a 5.7 LT motor) to my 5.3 My PCM is a 2002, from a 5.3/4L60E truck. I've read that I'll need to use an adaptor plug (4L60E has a different plug than 4L80), use a spacer, and oval the holes on the flexplate. My PCM has pins for 4L80E, but I can't find much info on how to wire the 2nd VSS plug. Any help would be really appreciated!
