I started coming here 2 years ago after my factory warranty expired. My only regret is I didn’t start coming sooner. There isn’t another diesel shop like this around.

Matt at Champion Transmission was highly recommended to me as a fair priced and honest mechanic. They certainly lived up to the recommendation when I needed a new clutch. The new clutch feels great! I appreciate the constant communication and manner in which we conducted business. I will be using them from now on as my go to mechanic! Thanks to Matt and his team.

I had Champion Transmission fix a blown transmission in my Chevy Tahoe, they listened to my concerns and suggested upgrading certain parts to avoid any future failures. Their customer service is top notch as is their knowledge of anything automotive related. I will not hesitate to use them again if the need arises

Champion transmission helped me out quick and saved me hundreds on replacing my transmission. I recommend them. Thanks again!

I have brought multiple vehicles to them. The only people I will trust to work on my cars. I never had a bad experience with them
