I took my 07 silverado diesel lbz it was having really bad transmission issues. Ended up being the wire harness on the transmission. Very happy with their service. Got my truck back running right the next day.

They are a very busy auto shop that’s been in business 40+ years. They were up front about time line for repairs and I found them to be fair in their pricing. I will use them again if and when I need repairs in the future.

Owners were honest and upfront with what needed to be done and price was reasonable. They also stayed open late so we could pick up our vehicle after they had closed because we couldn't make it in time. Would definitely recommend reaching out to them.
