Transmission Repair
A transmission problem does not always mean a new transmission. Plenty of shifting complaints come from things outside the gearbox itself. That is why diagnosis comes first.
Common transmission repairs range from simple to major:
- Fluid leaks from pan gaskets, cooler lines, or axle seals
- Faulty speed sensors or range sensors that confuse the shift computer
- Shift solenoids and valve body problems
- Software updates on some newer vehicles
- Torque converter problems, often felt as a shudder
- Internal repairs or replacement when clutches or gears are worn
Symptoms worth acting on
Slipping, delayed engagement when you shift into drive or reverse, harsh or erratic shifts, a shudder at steady speed, and a burning smell all point toward the transmission. So does red fluid under the car. Driving on a slipping transmission can turn a moderate repair into a major one, so it pays to get it checked early.
If a warning light is on, our vehicle diagnostics service reads the transmission codes as part of the inspection.
