Hoping someone may know of a good shop to do this. I bought the genuine cooling systems transmission cooler kit and am looking for a shop that has installed these kits before in the Houston area. Any contacts to share would be greatly appreciated-

No contacts to share but some guidance.

I did this myself on my 2019. It wasn't hard at all. The hardest part was putting the hard lines in. A bit of trial and error and they will go into place.

The system I got took out 50+ degrees off the fluid temp.

I left the thermostat pinned.

I'm 4 years in with no issues.

Called a couple of transmission places in Houston area and they sounded perplexed…

Might have to figure this one out.
