JC from Jim Jennings was just great. I brought my car in because our was making a squealing noise. He drove out for about 10 to 15 miles to make sure he was hearing what I had described and also did other diagnostic test ..ALL FOR FREE.. only to determine it was in fact my transmission. He was able to find out became I had pretty low millage my car would still be under factory warranty. This means it goes to a dealership and Jim Jennings transmission won't get the work. I would definately recommend this automotive shop to everyone living within a 25 + mile radius to go here for any engine or transmission work. They were honest, kind, explained everything so even I understood what was happening with my car. GREAT PLACE, GREAT PEOPLE!!!!!!!!!

We have an old '95 Saab 900 convertible with a five-speed standard, and I couldn't find anybody willing to look at it - reverse was shot. Jennings undertook the job, and rebuilt it. Works great, and it was delivered in the time promised. Thanks JC!

Five stars...five million...Th...

Five stars...five million...This shop is exceptional. We have had the pleasure of using them times. I wish they did everything from tires to detailing because I would be there all the time, they'd prob get sick of me..if you are unsure and leary of who to trust with your baby Id bet my house on them, you will have a peaceful trusting experience. There is no better anywhere....



Not just honest, but honorable.

Our 12 year old Honda was (apparently) having some issues with the transmission. Given the age, and general decrepitude of the car, we wanted to see if it was just a bad sensor, or something more serious (and unlikely to be fixed...). Imagine our shock when the fault could not be duplicated. Jim Jennings took the time to make sure that the fault wouldn't come back, and, after putting many hours of labor into diagnosing the non-issue, only charged us for the gas they put in it for test drives (oops, sorry about that guys). There is a reason we drive all the way over to Essex, and this is a perfect example. Given that for most of us the transmission is the most expensive part of our car we are ever likely to have fixed, it only makes sense to take it somewhere you can trust you are getting the work you need to have done, the best that it can be, at a reasonable price.

The Best

Worked on all my cars for years they are the best in the business and have been around for over 50 years. Super Friendly everyone I know at some point has gone to Jim Jennings Transmissions. Keep up the good work!!!



Outstanding Service!!

I have had transmissions replaced in 2 vehicles by Jim Jennings Transmissions over the past 10 years and they have proven to be a company of their word. They have stood behind their work whenever adjustments needed to be made & always have taken the time to check things out thoroughly. In my opinion, they're the best!
