💯

This repair kit is hard to install, and would be nice if it had a few more round disks to make up for the ones you will destroy while trying to figure out how to use it. But one you figure it out, while still not easy, how do you argue with a successful repair? After all, if it was easy, it wouldn't be a gm product needing the fix. It solved the problem.... now onto the other never ending list of breaking stuff on this car!

ممتازة ونتمنى ان يتوفر الاصلي منها

Work great easy to install. Took care of the engine light and shifting problem

These are excellent, and super easy to install, better than paying a transmission shop to do a hour job. It does come with a one extra so make sure you get it in correctly. The tool is easy to use too. I would recommend using fluid when installing them into the plunger. It goes more smoothly. And make sure you use the tool, the boot part to seal the rubber piece in. You can use an eraser on a pencil to make sure it doesn’t move, and I used air to make sure it was sealed as well.

The installation kit is great, the quality of the sensor covers feels better than stock, and the rubber seals feel better than stock. I installed these in July of 2024. The vehicle ran great, had perfect pressure to each sensor, and didn't even hiccup until recently. In October of 2025, the 2nd switch failed again. Caused the vehicle to go into limp mode on the highway, so will have to replace these again when I can. That doesn't mean they wont last on different vehicles, more than likely just an issue with the first gen of the Buick Enclave transmissions unfortunately.
