Very professional and once the parts came in my truck was done very quickly. The staff is highly knowledgeable and very pleasant to deal with and is the cheapest around with the BEST warranty for their work, and the staff is extremely honest and trustworthy and, I cannot say enough know what they are doing. I hope I don't have any transmission issues in my other truck but if I do I know where I'm taking it.

I had my vehicle serviced at Holabird Fleet Services, what a big mistake total nightmare, Larry Flint a total jackass, does not support customers complaints, he will tell you his jack legg mechanic Tony knows what he doing so with that said the customer complaints worthless, Holabird Fleet services would not honor my 3 year. 1000,000 mile warranty after i spent $4100.00, so I had my vehicle towed to Jim Jennings I must tell you service writer Steve was very very professional took the time to explain everything, I picked up my vehicle and I must tell you my 2015 Town and Country runs like a Boeing 747, I could not ask for anymore I would recommend Jim Jennings to anyone the work is excellent. So with that said (IF YOU DONT WANT TO LOSE A PENNY THEN BRING YOUR CAR TO JIM JENNINGS)

This review is an update from my prior review. Once I drove my vehicle off the lot, within 3 hours my car was overheating. I called Jim Jennings back and they had me bring the vehicle back immediately. They checked everything and replaced two parts. They showed me the two parts and the one part was cracked. They said it had nothing to do with the transmission, They did the additional work free of charge. I really appreciated that gesture. The guys were very kind, understanding and professional. Thank you Steve and JC. P.s. My motor died two days later. Sue Guinn

It took a whole week before they worked on my car that sit on their lot. When I picked it up I smell antifreeze and the inside of the car stunk. I took it back they did repair the antifreeze line of is cracked bye I guess one of their men working on it. They did take care of that but now I'm left what's an engine light on all the time. But they did do a good job on the transmission.

My transmission started slipping and I made a drop off appointment for Thursday morning. I dropped it off at 9am. Around 4, I called to get a status. I was told it s usually 24 to 48 hours before they would get back to me and that I should have been told that when I dropped it off. I wasn't. I was once again assured they would call when they had a diagnosis. Well, here it is 3:30 Saturday afternoon. Not only have I not heard from them, they are closed until Monday morning. I don't have access to another vehicle. I will update my post when I get my car back.

Jim Jennings Transmissions is my go-to place for any transmission issues and I'll explain why in this review. I currently own a 2010 Hyundai Genesis coupe. At 103k miles, my slave cylinder had given out, as I was out and about on a Friday afternoon. I had no idea what I was going to do, or who to call, stuck in the middle of an intersection with a bunch of angry people behind me.
I had called a couple different shops around the Baltimore area, but even they had recommended I go to Jim Jennings for the repair. And boy, am I glad I did. The folks at Jim Jennings were incredibly honest and communicative through the entire process. They got to my car quickly, let me know what the issue was, and let me know my options for fixing it.
I went ahead and asked them to replace the entire clutch assembly, and they were able to do so within a single day of getting the parts. I ended up getting my car back 2 days before they had originally estimated the repairs would be done, despite them having 6 cars to do repairs on ahead of me. As well as working quickly and doing the job right, their work is very reasonably priced.
It's hard to find a shop that will do good work without absolutely breaking your bank, but Jim Jennings did exactly that. As well as doing very reasonably priced work, they also offered warranty with their repairs, as long as I bought through their vendor, which was only a little more than I was able to find on my own. It is very much so worth paying a bit extra for warrantied parts.
All in all, I had an amazing experience at Jim Jennings. One week later (of not so nice driving) my clutch is strong. No slips, grabs lower in the pedal, and grabs hard. For as long as I'm in the DMV area, I will absolutely go to Jim Jennings Transmissions for any clutch or transmission related issues, and I highly recommend that you do so as well.

I knew I had some sort of issue with my transmission so my dad referred me to Jim Jennings. They definitely exceeded my expectations! The whole team is very professional yet friendly. After the problem was discovered, JC went over every little detail with me and helped me understand what he was talking about. He even advised what my best option would be without trying to take all my money like other places do.
When I went to pick up my vehicle, Gary, again, went over every detail to help me understand and even gave a little transmission education lesson. Jim Jennings does honest work and I can't thank them enough!

Finding a good mechanic or repair shop is much like finding a good doctor. It can be very difficult. When you do find one, you make sure to hold on to them! That's how I feel now about Jim Jennings Transmission. When the driver's side adjuster and axle stub detonated in the rear differential of my 2006 Pontiac GTO, I was sweating bullets. Didn't know if it could be fixed, or how much it would cost, or what I would loose in car quality and performance after the repair. J.C. worked with me at every step, sharing both the good & bad news, as the repair unfolded.
He was patient and took a creative approach to the direction of the repair, being willing to do some research to find a best solution for me. Before coming to Jim Jennings, another shop had quoted the only possible direction as being a complete rear differential replacement, with a factory re-manufactured stock rear. Since my differential had been upgraded, replacing the weak internals of the stock unit, I had no interest in going backwards in terms of performance or quality. So, repair, if possible, was the direction I needed to go in, and J.C. and the fine mechanic that did the work, found that path for me, and made it work.
The repair wasn't cheap, but I have no problem with paying good money for good value. I couldn't be happier, and any future drive-train work I may need done, Jim Jennings will get my business. I highly recommend Jim Jennings Transmission!

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.

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.

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!

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!

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

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.
