Review: WELL worth the cost..Don't do it without this! - 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!!!
Review: Works for 2010 buick - You can install with out removing transmission YouTube video to help.

Great kit. Love that it came with the tools. Definitely not a job for someone with no patience because you can damage these seals easily if you rush.
