Frequently Asked Questions
Do you repair both manual and automatic truck transmissions?
Yes. We service manual, automated manual (AMT), and automatic heavy-duty transmissions, including Eaton Fuller, Detroit DT12, Allison, Volvo I-Shift, and Mack mDRIVE units.
What are the signs of a failing truck transmission?
Hard or missed shifts, slipping, grinding, difficulty engaging gears, fluid leaks, overheating, and warning lights are common signs. Have it checked at 717-865-2388 before it leaves you stranded.
Do you repair or replace rear ends and differentials?
Yes. Along with transmissions we repair drivelines, rear ends, differentials, and U-joints, since these often wear together on high-mileage trucks.
Can you diagnose AMT and automated transmission faults?
Yes. We use professional diagnostic software to read transmission control module codes, test clutch actuators and sensors, and pinpoint shifting problems on automated and automatic units.
Do you rebuild transmissions or only replace them?
We do both. Depending on the damage and your budget, we can rebuild your existing transmission or install a remanufactured or new unit, and we will explain the trade-offs first.
How long does a transmission repair take?
Clutch and minor repairs are often completed in a day, while a full rebuild or replacement takes longer depending on parts. We provide a clear time estimate after diagnosis.
Do you offer mobile transmission service?
We diagnose and handle many clutch and linkage issues on the road 24/7, but major transmission rebuilds are completed in our Jonestown shop. Call 717-865-2388 to arrange service or a tow.
What payment methods do you accept?
We accept EFS, T-Chek, ComData, WEX, Fleet One, all major credit cards, and cash.
