 Trustindex verifies that the original source of the review is Google. If I could give more stars I would. These guys were honest, kind, understanding and fast. Thank you guys for making our experience So great! We will recommend you to everyone. We needed our radiator fan replaced. It went out abruptly after getting back from the airport. We live two hours away and it was a holiday weekend. They answered the phone and got us in immediately. We did have to get a hotel for the night, but we came to them after 5pm. The next day they were completely done and we were able to get home early in the day. Thank you again!!

Common Transmission Questions

What are the signs my transmission is going bad?

Slipping, delayed engagement when shifting into drive, harsh or jerky shifts, whining or grinding noises, a burning smell, fluid leaks or a check engine light. Bring it in early — small problems are much cheaper to fix than a failed transmission.

How much does it cost to fix a transmission?

Minor repairs typically run $150–$500, moderate repairs $500–$2,000, and a rebuild or replacement $2,000–$5,000 or more. The exact cost depends on the vehicle and the damage, so we diagnose it first and give you a clear recommendation.

What warranty do you offer?

Qualifying transmission rebuilds and replacements are backed by a 36-month / 40,000-mile warranty on non-commercial, non-modified vehicles. Your service advisor will go over the complete terms before any work begins. Warranty details

Do you offer financing?

Yes. We offer financing on transmission repairs and rebuilds, including zero-interest short-term options. Learn about financing

I live outside the Valley. Can you help with towing?

Northern and Southern Arizona residents can get $200 in assistance toward towing their vehicle to our Glendale shop. Transportation assistance
