4L80e rebuild kit
Verified Buyer
Mostly worked as expected. Ordered the bushing kit on top of the rebuild kit, and the pump rear stator bushing was the wrong size. Had to order a new one. Besides that everything went smooth.

Verified Buyer
Right on! Got the kit and is all back together. Everything looks good. Maybe add an option for beer shipped with the kits, I ran out about half way through.
Thanks for the recommendation Paul. We'll take that into consideration. :-)
