"As a wildland firefighter my truck is my lifeline. Thought I had a bad transmission but they found it was a turbo sensor. Richard communicated perfectly what was being done. 10/10 would recommend."

"My truck was throwing codes, they took me in immediately and scanned it. All it needed was a transmission service — $200 cheaper than the other shop. Very happy!"

"Chris took care of our Church van right away — a problem inside the transmission. Took it Friday, had it back Wednesday. It shifts smoothly and feels like a new van. Thank you Chris!"
