Hey everyone, so i know you guys all recommend swapping over to the 4l80e but i just don't want to do that, this trans has lasted 220,000 miles, driving pretty hard, (maybe i got lucky). So yesterday it started slipping when shifting from 2nd - 3rd under partial throttle, (i have not tried WOT) because i need it to last me a couple more weeks before i can tear it apart. do you guys have any rebuild kits you would recommend? Ohh and this is in a crew cab 06 silverado with a 5.3. Intake, headers, tune, 3.90s and detroit truetrac.

any advice will be appreciated.

 

Talk to dana hes hard to get ahold of sometimes but he knows his stuff and rebuild kits are worth the money....https://www.700r4l60e.com/store/home.php?cat=62

 

try Tru TechHigh Performance Transmissions and Automatic Transmissions Parts at trutechtrans.com
they have kits that use 7 frictions for 3-4 setup (stock uses 6)
It is what the 4L65E has in it 7 frictions plus a few other upgrades.
Give them a call they are very helpful.
Also search mrvedit over on ls1tech, he helps a lot of guys with rebuilds.
