How We Handle Semi Truck Transmission Repair
A transmission problem does not automatically mean the complete unit has failed. Slipping, delayed engagement, harsh shifts, warning lights, leaks, noise or a no-move condition can also come from the fluid, electronic controls, wiring, sensors, clutch, driveline or communication with the engine. Transmission work is one of the repairs our semi truck repair shop handles in Matthews.
When a truck comes in for semi truck transmission repair, we start with what the driver experienced and when it happens. We review the available fault information, inspect the fluid and visible leaks, check electrical connections and perform the mechanical or electrical tests that fit the symptom.
Once we know what is causing the problem, we explain whether the truck needs service or adjustment, a control-system repair, clutch or driveline work, component repair or deeper transmission work. We give you the parts and labor estimate and expected timing before you approve the repair.
We perform semi truck transmission repair at our Matthews shop for trucks working throughout the Charlotte area. Completion time depends on what we find, parts availability and current shop capacity.
Manual and automatic transmissions
We work on heavy-duty semi truck transmissions, manual and automatic, including transmission swaps and clutch replacement. We do not rebuild transmissions. That includes Eaton Fuller 10, 13 and 18-speed manuals; automated manual transmissions such as the Detroit DT12, Volvo I-Shift, Mack mDRIVE, PACCAR TX-12 and Eaton Endurant; and Allison automatics in medium-duty and vocational trucks.Clutch replacement
Slipping, chatter, a pedal that feels wrong on a manual, or clutch faults on an automated manual can mean the clutch is worn out rather than the transmission. We check clutch wear and adjustment before recommending a clutch job or a transmission swap.Axles, differentials and driveline
Besides transmission swaps and clutches, we repair the driveline on semi trucks: axles, differentials and rear ends, U-joints and driveshafts, plus trailer axles. Listed prices include central bearing replacement $300, driveshaft yoke $350, and differential oil change $50 per axle. U-joint, axle and differential repairs are quoted in writing after inspection.

Questions Drivers Ask About Transmission Repair
Call us for semi truck transmission repair when the truck slips, engages late, shifts hard, misses shifts, makes grinding or other abnormal noise, leaks fluid, shows repeat fault codes or will not move as expected. Different problems can feel similar from the driver’s seat, so we test before recommending parts.
We start with what the driver experienced and when it happens. Based on the truck and symptom, we may inspect fluid and leaks, review fault information, check controls, wiring and connections, and determine whether the clutch or driveline is involved.
Clutch replacement is usually finished the same day, and so are most other repairs. If a job needs parts ordered in, or your truck arrives near closing, we finish it first thing the next business morning. If a part will take longer, we will tell you upfront.
Remote or mobile support may help us decide the next step, depending on technician availability. Most internal transmission, clutch and driveline repairs need the tools and inspection available at our Matthews shop. We can arrange transport through an independent towing company when needed.
The estimate depends on the diagnostic time, what failed, the required parts and labor, the transmission type and whether the clutch, driveline, controls or wiring also need attention. We explain the estimate before you approve the repair.
Truck Pit Stop warranty applies when we supply and install the parts. Customer-provided parts are not covered for parts or labor. If we source and install an OE dealer part and the dealer later accepts a warranty claim, the dealer covers the replacement part and we cover the associated warranty labor.
An overhaul, or rebuild, means taking the transmission apart and replacing its worn internal parts. We do not rebuild transmissions. We diagnose the problem, replace clutches, and swap in a replacement transmission when the unit itself has failed. Transmission remove and install is $1,200, plus the replacement unit.
