Report
Suppose to have trans. serviced. Oil change. Filter change. Fuel filters changed. Tires rotated. Used these guys for the last 20 years for transmission services. The truck was picked up. I spent $850.00 for all of this to be done. Truck came back with oily hand prints around the truck. Steering wheel was full of oil. The bottom of the truck is full of oil and transmission fuel. There’s actual oil on my hitch in the back. Will need to get it cleaned and make sure I don’t have a leak. I have a puddle of fluid under where I parked it. I’m only 4 miles away from the shop and the oil is black

Friendly, fair mechanics. Took my wife's truck in because if transmission issues. Really thought we would need expensive repairs. They were truthful and did no extra work. Got it fixed for $80. Would definitely go back.

When you go there for car repair work Carlos is very up front and honest when evaluating your car troubles. I have had several repairs on my vehicle and can't say how please I am with the work done on my vehicle.
