Let Us Solve Your Transmission Problems

Got transmission problems? Has the check engine light come on? You depend on your car or truck to get you to and from work, to take the kids where they need to be, to run errands and more. We get that. That’s why you can depend on us to diagnose the problem with your vehicle and fix it quickly, to get you back on the road as soon as possible. And we stand behind our work, offering a 2 year, 24,000 mile guarantee on all work.

 Common Transmission Problems

  • Vehicle hesitates or refuses to go into gear
  • Whining, clunking or humming
  • Leaking transmission fluid
  • Grinding or shaking
  • Burning smell (not rubber)
  • Check Engine Light is On
  • Transmission is Noisy in Neutral
  • Gears Slipping

If your vehicle is exhibiting any of these problems, don’t delay. Transmission problems fixed early enough can prevent further damage to your transmission. Call us at 410-r20-6500 to schedule a service appointment.

And if after a thorough diagnosis, we find the problem is not as serious as you thought it was when you brought your vehicle in, we’ll tell you, rather than try and charge you for repairs you don’t really need. Heck, we’ve even made minor adjustments to a vehicle for free. We believe in honesty and integrity in all we do.


We are known as an honest, dependable and affordable transmission repair shop. Our expert mechanics have experience with all makes and models, foreign and domestic.  Whether it’s your sweet little sports car, your luxury sedan, or your minivan or your work truck, we have the expertise and training to evaluate the situation and make the needed repairs or even rebuild the transmission.

Need a Used Car Inspection?

A used car inspection is a good thing to consider if you are thinking about buying a used car or truck. Getting it checked out for issues first can save you money and headaches. Call us to schedule an appointment, and we can let you know what repairs have been made, what repairs need to be made, and what repairs will likely be needed in the near future. The charge for such an inspection will be based on how thorough you want us to be. A CarFax report won’t tell you everything you need to know about a used car, but an inspection at Harford County Transmissions will.

Most dealers and individuals will allow you to take a car off the lot (or off their property) to have it inspected, but some won’t, for instance, if the car is being sold “as is”. Auto dealers may send a salesman with you to our mechanic’s inspection. An individual seller may offer to drop the price then and there.

Most reputable auto dealers spend time and money reconditioning vehicles for sale, and have nothing to hide, so have no problem with you talking the vehicle for an inspection. Those who balk, though, are raising a red flag.

Call us at 410-420-6500 for emergency towing or to schedule a service. If you need to leave a message, someone will get back to you as soon as possible.
