Chris was great to work with, have heard nothing but good things. Just picked up my built trans from him today. Looking forward to installing it. Thank you.

Highly, Highly, Highly recommend Harmon Performance Transmission. I brought my truck in as my Transmission was giving me issues and they diagnosed the issue and walked me through it and showed me what was causing the issues. Honest, Friendly, and professional. I will forever bring my vehicles to Chris and the team at Harmon Performance.

I live in California and used Harmon. I paid $600 in shipping round trip, best decision! Chris knows transmissions and more importantly his customer service is better. I called around locally and did not get straight answers so I emailed Vice Grip Garage and he sent me Harmon, thanks Derek!Service: Transmission

Chris is very knowledgeable. If he can't fix it, it can't be fixed!

I had our truck transmission go out and Harmon had me back on the road sooner than anyone else could even get a reman transmission to their location. I've been a mechanic for 26 years. Installed plenty of reman transmissions and worked with several dealerships and repair shops during that time. Harmon has some of the best customer service by far. They went out of their way to keep me informed on the process of my repairs. The what and why was answered with knoweledge that only comes from a crew that truly enjoy their specialized field. They also stayed well within the original estimate. I would highly recommend them to anyone.Service: Transmission

Chris is a rare find. His honesty and professionalism is unwavering. Even on a difficult and time consuming rebuild he never cut corners or compromised his work to get it done and gone. As a result, I have a solid running truck that I can trust to pull our camper cross country for years to come. If I am in need of transmission services again, my choice will be easy.

Chris built me a Th400 for a nitrous car a couple years ago, we have been pounding that thing for 2 years and well over 150 passes and it still runs mint and shows no wear at all. This is the local place to go for a transmission that can take a punch.Service: Transmission

Great guy who does great work. He has taken care of all my transmission needs for going on 14 years now. Everything from upgraded stock replacements to high horsepower builds.
