Re: 4L60E or 4L80E Transmission?

I run 80e's, & take the 60's to the wrecking yard. but that is just me. I would look for a deal on an 80e & if one falls into your hands use it. I find them in chevy express vans sometimes for pretty cheap, last one was $225. The OD clutch pack was a little worn, threw a tansgo shift kit in & running over 600 rwhp at it for 15k hard miles so far. I have two extra in the garage now just because I found deals on them.

You have to add a wire to the PCM for the second VSS, switch a wire on the trans plug, & get a segment swap for the pcm if you have HP Tuners. It's simple.
