2010 Buick Lacrosse back in business! Wow, and Awesome. I don't usually write reviews, but this worked SO great. It was a huge pain getting to this point (and putting everything back together), but this tool set was great. 2/4 of my disks were shot, and one was about to fail. Hope this lasts, but it definitely fixed my transmission. 8 hours of labor to take apart, and put back together for a $20 part....well $1 part as its the simple little clear plastic disk that fail. But MUCH less than a new transmission!!!

Worked fantastic in solving some drivability issues

Great product needed instructions tho. We u tube it !

So happy that This kit Fixed 1-2 shift flare on my 07 Yukon with 6l80e.It sure beats buying a new TECM or a whole new transmission.It took a few special sockets to drop the valve body and pull off tecm to rebuild. One socket was a “female torx plus 12” , and I think a couple other more common sizes.It took a few tries installing the new seals but we got it done without messing any up.I wouldn’t recommend trying to DIY this unless you have some prior auto experience, because this does take a slightly higher skill level than some other repairs.YouTube was very helpful with directions on how to replace, with Lots of videos out there on this exact repair.If you took this kit to an auto shop they would charge you several hours to do this repair.Probably only a transmission specialist will know about this repair and be willing to do it.I work at a general repair auto shop, where we do all kinds of auto repair including transmission repair, but no one I work with has heard of this kit. Every one told me it needs a tecm.It took me personally about 2-3 hours to installThis kit can fix all kind of issues with 6l80, and other transmissions. It’s known to fix shift flares, hard shifts, transmission fluid pressure switch voltage codes, etc.basically anything that could be TECM related on a 6l80e, I would try this kit before replacing any bigger or more expensive parts.

The included tools definitely helped, but the included seals did not fit reused old seals they had no damage and replaced the cracked laminated disks with the new ones from the kit.4 stars because of seal fitmentGot the dang 6L80e shifting smooth again 💪

Bought this to use based on a video from the YepThatsIt YT channel. My truck has a shudder from a stop and a hard shift into 3rd and 5th gear. I also sometimes got a delay into 3rd or 5th gear. Paired this kit with an ACDelco seal kit 24238925. That's all the rubber seals except the pan seal involved in removing and re-installing the TCM. The kit here fit perfectly in the transmission. I had 2 torn orange plastic disks and the 1st one was black with crud so I'm sure that wasn't helping anything. After install of the kit it's been 3 days and a hundred or so miles and everything is working much much better now. The tools worked great, I recommend getting a kit of seal picks too. An All Data subscription can walk you through the tightening order and spec for all the bolts during reassembly.

Issues, rubber grommets dont fit, too thick, have to reuse old ones, tool was bad machined make it useless, have to improvise to install grommets, This issues are easy to resolve, dont undestand why simple things pass by Quality control and custumer have to improvise, next time will buy sonnex ones to avoid this problems.

The kit with tools worked great for our 2009 Enclave that wouldn't shift out of 1st gear. Read the instructions and watch a few YouTube videos and be careful.
