We brought our 33' RV to Newcastle for transmission repair and an engine tune-up in June. We then drove it to Maine, about 600 miles or so, from Maryland and back. We never had one problem!! Our gas mileage improved, shifting was much better, and we couldn't be happier.

. I really appreciated the patience of yourself and the mechanics at Benchmark Transmission when I returned the vehicle assuming that the transmission still had problems; and I respected your offer to refer the vehicle and your honesty in identifying the further problem of a clogged fuel filter. The van has run very well since its most recent repair. I will be sure to make reference Benchmark transmission to my friends and family.

have had nothing but the best service from Joe at Benchmark. I heard about them from a friend (the best kind of referral) and I was not disappointed. I had my car fixed at Benchmark a few years ago and it has been going strong ever since
