I am writing to let you know how pleased I am with your company's repair and service of my 2000 Hyundai Sonata. It arrived in your auto repair shop in Newark Delaware with a defective speed sensor. Benchmark Transmission offered to repair the transaxle for a very reasonable price. The dealer replaced a sensor previously at a higher cost. The transaxle is performing like it did a few years ago, up shifts and down shifts are smooth again.

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

Benchmark saved me a trip to the shrink.What I thought would be a stressful day, hundreds of dollars in repairs and a missed dinner reservation for Valentines Day turned into an amazing day.Long story short: I just began a new job in Newark. I spent all of my most eyes on moving expenses so I was low on cash. It was the day after a major snowstorm so tow trucks were arriving late and several car shops were closed or couldn't work on my car
