Honest/Ethical Business!! I recently took my vehicle (Toyota Rav4) to Benchmark in Middletown, DE regarding a thumping I was experiencing in the auto transmission when changing gears. Not only did they check the vehicle free of charge, but they identified a recall on the year model I own (2003). The manager Mitch contacted me and told me the good news and said the service manager at Toyota was waiting for my call to schedule

Mr. Dante Principe Jr.,Two weeks ago, I took my 98 VW Golf to the Smith VW dealer for a non-transmission related problem. Upon completion of that work, the dealer told me that my 2nd gear on my Automatic Transmission was sticking and that I needed a new transmission. I told them I did not want them to do that type of work on my car. I decided to get it checked out by an expert at Benchmark Transmission before I did any damage

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
