Any car part manufacturer will tell you that preventive maintenance is critical to the part's lifespan. Like other auto parts, car transmissions aren't built to last forever.

Transmission Repair
Our services include transmission repair on both manual and automatic transmissions. The first step in getting you back on the road is assessing your transmission to accurately determine the source of the problem. In some cases, we are able to repair your transmission simply with adjustments, replacing external seals, or replacing accessible parts. To have this done by specialists, call 301-829-6100 to talk to the mechanics of Twin Ridge Auto and Light Truck Service today.

Transmission Flush
Although most manufacturers recommend a transmission flush every 30,000 miles or every two years, some symptoms may indicate that you need a transmission flush sooner. Some of the symptoms that indicate that your car needs a transmission flush sooner are: transmission grinding or strange noises, problems shifting gears, slipping gears, surging of the car, and delay in vehicle movement. Flushing the used fluid from the transmission washes away tiny particles of dirt, clutch material, and metal shavings. For all your transmission flush needs, call 301-829-6100 or visit Twin Ridge Auto and Light Truck Service today - we are transmission experts.

Timing Belt
A timing belt is a part of your car's internal combustion engine. The belt synchronizes the camshaft and the crankshaft rotation so that the engine valves open and close at the correct timings. Also, the belt prevents the piston from striking the valves in an interference engine. A timing Belt is a rubber belt that usually features teeth on the inside surface, while a timing chain is a metal roller chain. Most cars we drive now have timing belts instead of timing chains and gears. Although different manufacturers have their recommended mileage, you need to have your car's timing belt checked regularly. To have it checked by experts, contact Twin Ridge Auto and Light Truck Service today.


What Our Customers Are Saying

We have had Scott and Earl work on our cars for over 20 years. They helped us get 430K out of our Toyota Echo before the A/C failed and it just didn't make economical sense to repair. We know they will always give us an honest opinion on what needs to be done and charge a fair price. They are a pleasure to work with.


-Stephen S.

Scott, Eric and the gang are a good bunch to work with. Having worked in the industry myself for a number of years, I know when a shop doesn't have it's stuff together. They are honest and do a good job.....what more could you ask for?


-Craig K.

Trustworthy, kind, and fair. What else could you want or expect from your mechanic? We wouldn't take our cars anywhere else.


-Janine M.

Great service and I can trust them with my car. Highly recommended.


-Michael C.
