How do I know if my transmission needs attention?

Common signs include unusual noises, slipping gears, or delays in shifting.

How much does a transmission repair cost?

Costs vary based on the extent of damage and type of vehicle. When you contact us for an estimate, please be ready with your complete VIN or at a minimum year, make, model, sub model and engine. The more information you can provide, the quicker we can give you an estimate.

Do you provide warranties on repairs?

Yes, we offer transmission rebuild warranties as well as warranties on general maintenance. Please inquire for specific details based upon the work being performed.

Do you do work other than transmission repairs?

Yes, we perform most general maintenance on vehicles, but we prioritize transmission work. We do not overhaul engines or do internal engine repairs but can recommend where you can take your vehicle for that kind of work.

What payment methods do you accept?

We accept major credit cards, cash, and checks. We do not have internal financing but can accept Synchrony Car Care Credit, which you can apply for if you need that option.

"Had an emergency with my transmission and they identified it as a bad torque converter, fit me in the next week despite them being very busy. 1 year / 12k mile warranty included. They were very honest with me every step of the way. Truck has been running fantastic for a few weeks, trans fluid temp has been staying low."
