What Is A Transmission Solenoid?
Everything that happens inside an automatic transmission happens because of hydraulic pressure. There are circuits machined throughout the inside of all automatic transmissions that carry fluid under intense pressure to different compartments to cool, lubricate and apply pistons. Those pistons apply clutch plates for reverse, 1st, 2nd, 3rd, 4th, 5th, 6th and recently for 7th, 8th, 9th and 10th gear.
The component that causes the fluid to flow into the respective circuits at the correct time is a solenoid. A transmission solenoid is an electro-hydraulic valve that controls fluid flow into and throughout an automatic transmission. Solenoids can be normally open or normally closed. They operate via a voltage or current supplied via the transmission's computer or controller. Transmission solenoids are usually installed in a transmission valve body, transmission control unit or transmission control module.
It is interesting to know your refrigerator's ice maker, dishwasher and washing machine use the same technology.....solenoids.

"The best place to have transmission service. Saved me over $200 dollars on a Fluid and Filter change on my Jeep CVT compared to dealer price. Very nice people to deal with and they provide a nice clean waiting room while I was there. I enjoyed my conversations with Mr. Jennings while I was waiting."

Ron Rubenstein of Rosedale Maryland
"I got the recommendation to contact Jim Jennings Transmissions to look at my transmission repair problem from my son-in-law. I am so glad I did. The service was outstanding and they treated my vehicle as if it were their own. They did a full transmission computer diagnosis and found the issues and contacted me to explain everything that needed to be done. They didn't pull any punches and were up front and honest about everything. All transmission repairs were discussed along with the cost and importance of each. I had them go ahead with the repair and the results were outstanding. Not only does the vehicle run likes its brand new they were right on the nose with the cost. No hidden fees, no extras. I will recommend Jim Jennings Transmissions in Baltimore to anyone I know that is in need of transmission service and I will definitely be taking my car back there for check-ups and any future repairs. THEY ARE THE BEST!! Thank You Jim Jennings"

"I had been trying to track down and resolve a drive line vibration in my 2002 Ford F-150 for about 3 years. I've taken my truck to many repair shops, all of which half-way listened to my theory of what might be the problem, and proceeded to throw parts at it (new shocks, new tires, wheel bearings, front end suspension work, etc) or blame the vibration issue on my modified suspension (6" lift kit). I have owned this truck since it was brand new and am rather meticulous about its maintenance and care. You really would have to see the truck to understand just how meticulous (she's real clean). Just when I was about to give up hope that I could have this drive line vibration issue resolved, a family member of mine recommended I give Jim Jennings Transmissions a call. I called and spoke with J.C. and could immediately sense he was a very knowledgeable transmission technician and actually listened to my theory of what might be the issue, as well as what all previously has been done to the truck in attempt to resolve it. I dropped my truck off in early February to have it looked at and ultimately picked it back up in early March. During its one month stay, my aluminum drive shaft was removed and balanced, as well as a complete rebuild of my rear axles and differential rebuild. To most people 1 month would seem like a long time to complete the work mentioned. But what they don't realize is the amount of effort Jim Jennings Transmission put in to investigate the problem, as well as any small change to the truck would follow with a call to me to come and test drive it to see if I noticed improvement. They would also make sure I was happy with the service and if I wanted to continue investigating. Between the drive shaft and rear axle work, I am now very pleased with how my truck runs. It's been a month since I picked it up and I'm driving down the highway with a smile now that the vibration issues are finally gone. As stated earlier, I've had this truck since it was brand new. We've been together a long time. I hope to have many more years and miles with this truck and if when I need any work that would require the level of attention to detail that this truck deserves, I will most certainly return to Jim Jennings Transmissions, as well as recommend them for their quality of work and compassion for their customers and their rides. Thank you all!"
They took it for a test drive, spent another hour with the car and advised that the ONLY problem is the lack of the transmission fluid that will cost us under $100. You are our ONLY transmission place!
Eleonora Q. of Timonium Maryland
"We appreciate your honesty and professionalism!! We used your transmission repair services and had a great experience! This is the story: first we went to another, closer shop, and about 30 minutes later they came up with a $2,500 estimate. The car was fairly new, so we had a hard time to believe that a transmission rebuild was needed. Thus, we took it to Jim Jennings Transmissions in Essex. They took it for a test drive, spent another hour with the car and advised that the ONLY problem is the lack of the transmission fluid that will cost us under $100. You are our ONLY transmission place!"
Again, thank you for your great service and we want you to know that it doesn't go unnoticed.
Paul Mahoney of Towson Maryland
"Thank you for the courtesies you and your people extended to us recently regarding our 95 Buick Roadmaster Wagon. A special thanks to the two of your transmission technicians, JC and Dexter, who actually walked me through our transmission problem. As in the past Jim Jennings Transmissions has again proved to be the most knowledgeable transmission experts we have ever dealt with! Your excellence and leadership has given us the peace of mind in dealing with a competent local company. As a company ourselves, with eight vehicles on the road, it is a must to keep our vehicles in top condition. We believe today that you shouldn't be in business only for the money and that the best in anything seldom goes bankrupt. Again, thank you for your great service and we want you to know that it doesn't go unnoticed."
I would like to say thanks again to Gary, JC, Ray and the entire Jim Jennings Transmissions' team. I was having a shifting issue that was intermittent and difficult to diagnose on my Dodge Ram (Cummins).
Joe Wilson of Baltimore Maryland
"I would like to say thanks again to Gary, JC, Ray and the entire Jim Jennings Transmissions' team. I was having a shifting issue that was intermittent and difficult to diagnose on my Dodge Ram (Cummins). The problem showed up on a Saturday afternoon and I called what I thought was the shop but the call was forwarded to Gary's Cell phone. I told him the problem I was having and he took time out of his day to meet me so he could computer diagnose what was going on with my transmission. I did not believe that this level of customer service existed anymore. I dropped my truck off the following Monday and it was determined the governor pressure switch and speed sensor were bad. I had it back on Tuesday fixed and educated on a Dodge 48RE Transmission. The level of knowledge that was exhibited was far superior than any shop I have gone to over my 48 years. Jim Jennings Transmissions cares about its customers."
Gary and his team are the best, THANK YOU! I have been telling everyone to go to JIM JENNINGS for all their transmission repair work.
Phil Blatcher of York Pennsylvania
"I didn't think it was still possible to get top notch, quality customer service anymore but, that's just what Jim Jennings Transmissions in Baltimore gives. They made me feel like I was their #1 customer. They repaired my vehicle's transmission ahead of the promised time and at a very reasonable price. My vehicle runs better then ever and all their work is under warranty. Gary and his team are the best, THANK YOU! I have been telling everyone to go to JIM JENNINGS for all their transmission repair work."
Their striving for honest, quality work truly showed with my experience on the phone and at the repair shop. I would strongly recommend Jim Jennings Transmissions to anyone else seeking transmission repair.

"While having trouble with my transmission (5R55S), I was reading online about how positive the reviews are with Jim Jennings Transmissions in Essex. I decided to take my car in and John Chalk (JC) checked it out on a test run. I was told I needed either a transmission replacement or transmission rebuild done. I chose to get the rebuild done. After the service was completed, I immediately noticed that all the troublesome problems I had before were now gone. My experience with Jim Jennings Transmissions and their team of well-trained transmission technicians from start to finish was nothing short of excellent. I would give Jim Jennings Transmissions an A for their service, quality of work, and their amazing amount of knowledge and expertise on transmissions. I was talked to as though I was part of their family. Their striving for honest, quality work truly showed with my experience on the phone and at the repair shop. I would strongly recommend Jim Jennings Transmissions to anyone else seeking transmission repair."
After 1500 miles later I am more than happy with their work ! The clutch engages so smooth now. I'm totally happy with the work . These guys will help you in every way they can to do it right the 1st time !
Kirby Summers of Baltimore Maryland
"Just wanted to thank Jim Jennings Transmissions for a very professional install of the clutch in my 2007 Ford Shelby GT500 ! I only had 32,000 miles on the used car and only owned it 2 months when it needed a clutch repair . I was the 2nd owner of this car . Researching this clutch online I found out that Ford had 4 technical service bulletin fixes on the premature clutch problems. Jim Jennings looked up my vehicle history and said that it had a new clutch replacement after 5,300 miles and showed me . They installed my aftermarket purchased McLeod RXT Dual clutch in a few days I was back on the road. After 1500 miles later I am more than happy with their work ! The clutch engages so smooth now. I'm totally happy with the work . These guys will help you in every way they can to do it right the 1st time ! I will be a returning customer as my son now needs a clutch for another 89 Turbo Supra he purchased."
