This Mister Transmission is great!...
Cidd
This Mister Transmission is great! I highly recommend them. They fixed the transmission on my Chevy Silverado faster than I expected. I didn’t want to take on new payments for a new truck, so this was perfect. On top of that, Dan went out of his way to redo the e-transfer so I could get the rewards on my Visa card. They really went above and beyond — I’d send anyone their way!

Kristin Stimers
I can't say enough on how pleased I am with the professionalism and competency of Dan and his staff. I've been burned before by shady mechanics and I can honestly say they are some of the best! Dan was polite and friendly from my first phone call, and he took the time to LISTEN to all my questions and answered them in a clear and kind way that helped me understand the problem. Not once did I feel like I was being rushed out of there. The problem (leaky transmission) was fixed in a timely manner and it was done well. He noticed another issue that was causing me problem (bad ball joints) but I never once felt like he was trying to "find" issues and upsell me. He solved this one as well and now my car sounds better than it did when I first purchased the vehicle used. I would definitely recommend Dan and his staff for not only transmission related issues but for all mechanical issues. The final bill was VERY reasonable. I'm so VERY happy that I found Dan at Mister Transmission. THANK YOU!!

Alex Greychuck
I had a transmission fault error right in the middle of a work week, Dan and his team got me back up and running in short order, when the problem came back, Mr Transmission had my back, took the car in checked it over, found the issue causing the signal and fixed it, at no additional charge. Dan and his team were very good about taking me through the issues and what to expect. Car is running better than ever now.
