I have had my cars transmissions serviced and repaired here over the years and the owner Dante is always upfront and honest in what is needed. If you have transmission issues I very highly recommend this Benchmark location. Service: Transmission

My daughter's car broke down on Ogletown Parkway the other evening and she called AAA to have it towed to a service station nearby. We were so lucky the car landed at Benchmark Transmission! We feared the worst (with all those lights that came on!), but the team at Benchmark gave us an honest and fair assessment of what needed to be done. They are trustworthy and give great attention to detail. We also got a AAA discount on service! We will be using them as our regular service station as long as our daughter lives in Newark!

I called here trying to make an appointment for my transmission and the gentleman on the phone said that they don't do engine work on anything. How do you not do engine work when transmission is apart of your name? The man on the phone blew me off and told me to call another place, which also did not do transmission work and rudely hung up on me speaking. I do not recommend this place, terrible costumer service.

My daughter's car wouldn't shift into reverse so we took it to Benchmark Transmission. We talked to Don about the problem and he test drove the car. He explained the problem to us and gave us a detailed estimate. I was expecting the worst but the estimate was very reasonable and we could have the car back the following day. That was 3 months ago. The car is driven every day and is good as new. I highly recommend Benchmark Transmission.

I had to have my transmission rebuilt. Dante, the owner, and Nate, the technician, did a great job! They were very quick and came in a little under their estimate. They also did a couple of other things for me that needed to be done, which saved me some work that I hadn't been able to complete. Overall, a very positive experience. You can trust them to take care of any transmission problems you're having!

When they ask if it is ok to take an extra bit of time to make sure that they have the pricing and diagnosis right up front. you know it is a Very Trustworthy place. This was the second time we needed service on a vehicle's Transmission and this is our go to mechanic for honest work, and the job done right the first time.

Very honest evaluation of changes required for my Honda minivan to operate and a good year long warranty given. The guy is knowledgeable, highly recommended to get transmission related issues checked here.

My sons 2004 Mini Cooper started acting up right after a clutch replacement. These early Cooper transmissions are notorious for bearing issues. The car was not worth dumping lots more money into but had low miles and was in great shape otherwise. I decided to pull the transmission myself and hope to find someone that would repair it at a reasonable price. Benchmark was recommended by my mechanic, Fair Hill Auto.
I brought the transmission to Dante in Newark and without question, he was willing to take a stab at the repair. Two bearings and seals later, the Mini is back on the road and feels like a new car. It shifts better than when we bought it at 80K! Thanks Dante!

Benchmark of Middletown is a great place with good honest mechanics. Ron and Mitch, the owner, were wonderful with helping me resolve my transmissions problem. They are also equipped and ready to take care of all your car mechanic needs.

I took my truck to Benchmark Transmission in Newark, Delaware. My vehicle had a manual transmission and the gears did not shift properly. I took my Tacoma in for a free estimate. I was later quoted $1300, I decided to accept the quote and have my repairs completed. When I first arrived at Benchmark they were friendly. After the work was completed and I went to pay for the repairs there was a change.
The customer service was horrible, when I walked in the employee did not speak to me, he just stared. When I asked him if I could be helped he spoke to me in a condescending manner. I remember thinking that if they acted this way before, I would not have had my vehicle serviced at Benchmark. After repairs were completed and I drove my vehicle, I noticed that it continued not to shift well and I was unable to put my truck in reverse.
After calling Benchmark about my problem and they said that the vehicle drove fine when they drove it, I decided that I wanted a new car anyway. My trade in amount was reduced by $2,000 because of the faulty repairs. With the reduction in trade in value and the cost of repairs I was out $3,300.

Contacted Dante through the site over the weekend with questions about a ballpark on rebuilding my transmission. Even though they were closed at the time he emailed me almost right away! I limped my car in on Monday and had it back on Thursday! They did a great job and were very professional. It's great to find a mechanic I can trust to do what they say they'll do and back it up. Thanks guys for a great experience!

I was having issues with my 2007 Hyundai Elantra where it was not shifting out of second gear. I looked up transmission shops near me and found that Benchmark Transmission had the top reviews. I called them and they asked me a couple questions about the problems I was having and then told me that I could drop it off the next day. Within two hours of dropping the car off Dante, the shop owner, called me to personally update me on the status of my car. Two hours after that received a call telling me they fixed it. Excellent service, excellent price, I would absolutely recommend Benchmark Transmission.

Report
I highly recommend Dante and Benchmark Transmission. Dante worked on my '09 Corolla's transmission at the end of last year. When he realized the work to be performed could only be done by the dealership, he was immediately up front about that. I was really impressed that Dante insisted that I stay in touch with him on the results of the dealership's work. But I was doubly impressed, when he took the time to call the dealership on my behalf when I was unsatisfied with the dealership's results, as well as the dealership's response to my follow-up.
Because of this, the dealership's follow-up work was satisfactory, and I owe it all to his efforts: above and beyond what could have been expected. It is not easy to find a trustworthy specialist when it comes to your car. But Dante Principe and his team at Benchmark are definitely someone you can trust.

I have been taking my vehicles to Benchmark Transmission in Newark now for nearly 25 years and have never felt more comfortable with the expertise and level of service that I have received. I have owned various makes and models, typically of older vehicles, and have always had the life expectancy of the vehicles extended whenever I wrestled with whether have the transmission serviced or replaced as opposed to necessarily getting another vehicle. It has always been well worth the cost.
Beth Weinman
These guys are great, and they really know what they're doing. If you decide to get any transmission work done, these guys are definitely worth it. They're really patient in breaking everything down for you, and they are truly invested in helping you make the best possible decision(s). After dealing with mechanics all over the US, I've got to say that these guys are some of my favorites. This place definitely comes with my top recommendation.

When my daughter's 14 yr old wrangler started leaking fluid and making a horrible sound we had it towed to Benchmark Transmission in Newark. They were upfront with what was wrong, how long it was going to take and fixed it at a reasonable price. I highly recommend Benchmark Transmission we have had various car makes/models serviced by them. Always a pleasure!

Dante and his staff did a great job on my GMC carpet cleaning van. Had the transmission out, rebuilt and back in in 2 days. Getting me back to work fast. Will recommend to any one who asks.
Vickie Sokolove
Benchmark rebuilt the transmission on my 2006 Odyssey last year, and I brought it back in today for its one year checkup. I was extremely happy with both encounters here--the first time the job was done right and I have had no further problems, and both times found Dante to be extremely forthcoming, informative and pleasant and willing to frankly discuss any issues related to my car (or potential future cars) with me.
