I’ve been dealing with GT transmission for almost 25 years. Great family owned local company that stands behind their product. Highly recommend them for anyone with transmission issues.
Mike Siedlecki
Our long time mechanic actually referred us to GT when our Jeep Grand Cherokee was getting stuck in 4 wheel drive mode. GT immediately tried to solve the issue for us. Ultimately we needed a new part which was ordered and installed. Our jeep is now running smooth again. Thanks for the friendly service and for troubleshooting our issue!

I Would 100% recommend this shop to whoever having some issues with their transmission. The staff took time to have a discussion with me, they were very helpful, they didn't push me to buy or replace unnecessary parts. very good shop, i will definitely come back if needed.
