Hello all,
I've been using your forum for awhile but for some reason never had account, so I figured I'd join the fun.
I am currently working on my 2001 ECSB Silverado 1500, it has ~90k miles and I am the 2nd owner. Currently the engine is a stock 5.3 with a 6l80e swapped in using a TCM-2650 from Zero Gravity Performance. I have a LQ9 sitting on an engine stand that I am currently rebuilding and will hopefully go in this winter.
I just completed the swap and only have about 500 miles driving with it, but its really a lot better than the 4l60e. The truck feels much zippier and is at a lower rpm cruising through town, on the highway its nicer to not have such a drastic RPM jump with each down shift. I still need to tune the shifts a bit more because right now it kinda kicks me in the ***. All in all it just drives pretty similarly to the 2013 I pulled the trans out of with a bit snappier shifts. I did a pseudo race with my friend who has the same truck and the trans did make it quite a bit quicker over the 4l60e.
As for the swap itself it was super easy, pretty much bolts right into place minus having to drill new holes on the trans mount. I used the newer style trans fluid lines and just used rubber hose to attach to the stock trans cooler. The stock tcase bolted right up but I had to swap the input shaft to a 32 spline input shaft. The stock shifter linkage works mostly, there's not enough throw to put it into 1. but P,R,N,D,3, and 2 all work normally. I am still working on getting a temp gauge installed and a gear readout (dash currently says it's in 2nd) and I want to get the reverse lights working.
I have everything sitting in my front room ready for this lol. My Tahoe needs it bad, Dan was roasting me last night about it. Interrupted my stalking sessions
I say send it. The swap took me about 2 days to complete with a lift, but I was taking my time and trying to get everything underneath the truck buttoned up pretty nicely.
Great! Thanks man! I am not sure if you read in the other thread there were some things I wanted to do while I had my truck apart, but it's getting to the point that I need to just sign on for the drama and get it done, can't be 2L60 much longer
Sweet!!! Pics needed for sure when you get time. I've got all my auto stuff in that I took out of the truck when I went to the T56 swap. The shift lever cable and what not. I'm keeping all the manual stuff in the truck so I can swap it out at will. I'm probably getting a 9" so i can swap the rear gear when I go back and forth to the manual and auto. Trying to turn my truck in to the next Big Red, google big red camaro.
