I highly recommend Jim Jennings Transmission for their great work.

I had an amazing experience by taking my sons vehicle to Jim Jennings to install a transmission. From the start until I received the finished product I was explained in detail on what is required in order to have the car operate properly. The staff was pleasant professional n nice, and the follow up was FANTASTIC. This experience has allowed me to have high standards and expectations when seeking service for any of my vehicles. I highly recommend others that if you are seeking to get your vehicle serviced or need a transmission placed in your vehicle that you take it to Jim Jennings Transmission. You will receive quality service from start to finish.

I recently had work done on my Jim Jennings Transmission,they did a excellent Job. They saved ma a lot of money,cause every other shop even the dealer suggested a new transmission that was to costly. Jim Jennings Transmission customer service was even better then most places..they made me feel really Confident that they knew what they were talking about & doing..they kept me informed of everything... I didn't have to call them ..they called me .I had a most pleasant experience with them & I would recommend to anyone that is experiencing any Transmission problems to give them a call,you won't be disappointed

We took our car here and it was the BEST decision in a week our car was like new. The mechanics at Jim Jennings were great. I would highly recommend this business for doing any work for you. You will not be sorry I promise. Thank you Jim Jennings Transmission and Jc. Awesome work.

The service was first rate and very thorough and professional from start to finish. I would highly recommend Jim Jennings Transmissions to anyone who needed any kind of transmission work done on their vehicle.

I would like to thank Jim Jennings transmission for taking the time to look over my car and take a drive with me. Their assessment was that it was not my transmission and told me what the problem was and even talked to my brother on the phone.
I left there owing nothing. It was a wonderful experience and I highly recommend them to anyone who is looking for a HONEST mechanic. Thank you Jim Jennings

Jim Jennings Transmissions couldn’t have been any better! J.C. always stayed in touch with me before, during and after the job was done. Steering me in the most logical direction. I got an upgrade transmission for my diesel pickup truck and couldn’t be happier with it and the service I have received. J.C. even stayed an hour late to let me pick up my truck. I met Gary too during my 2 week check up (I love the follow up, something no other shop I know does) and learned a lot. I wish I could give 7 stars!

Mr.Gary & the others was very profesional.I loved everything about their customer service.They found the problem and explained every detail to make sure I understood Everything!!!

I was having trouble with my VW and was new to Baltimore, so I took it to the dealership. Very quickly, they got back to me and told me I needed a very expensive brand new transmission - and that was my only option.

I quickly decided I needed a second opinion and found Jim Jennings Transmissions online. Persuaded by their good reviews, I drove out there and from the very beginning, my experience was fantastic. They put my car on the lift to show me exactly what was wrong, explained the various options to fix the problem with me, and helped me work with my insurance company. The staff are all super professional and polite, and I felt like they were being completely straightforward and honest with me, which I really appreciate.

I hope to never have transmission issues again, but if I do - I know exactly where I'll be headed!

I highly recommend this business to anyone that is having difficulties with their transmission. I was sent here for what was thought to be transmission issues; however, it turned out to be something different. Jim Jennings still fixed it for, even though they did not have to. When I had some issues again, they helped me out immensely. They take the time to explain what was wrong with your car, and teach you basic skills that one should have when owning a car. I would recommend this place to anyone, as their customer service is impeccable and they go out of their way for their customers.

My Father (former HotRod and mechanic) has been telling people to go to Jim Jennings since I was a kid (I'm now 36) "It's the only place I'd go" he always says plus I think he likes the fact that they've been around since he was a kid and that sparks fond memories of Super Cobra Jets and Mach1's.

I have been sending people there for years based alone on my fathers recommendations and everyone has been quite pleased. I have been lucky with transmissions in the past but I recently had my first transmission related problem and I had my car towed there and I found that everyone was very friendly. When I described the issue they did not want to speculate on what the problem could have been until they looked it over but they did give me a idea of worse to best case scenario to prepare me for what was to come. I was given a estimate for the repairs and I green lighted the work. I picked up my car and when I paid I found that the price was $80 less than the estimate, how often do you see that? I'll tell you... Never!

I'll sum it up by saying everyone I met was good people and I will stress that they are very honest and due good work at a very fair price. Hopefully I won't have to visit them again anytime in the near future.
