Experienced Automatic Transmission — General Service specialists since 1987. Free computer diagnostic, lifetime warranty on rebuilds.
A conventional automatic transmission uses a torque converter, planetary gear sets, and hydraulically operated clutch packs to deliver automatic gear selection. Unlike a CVT, it shifts through discrete gear ratios. Modern automatics range from 4 to 10 speeds. We rebuild, repair, and service automatic transmissions from all manufacturers — domestic and import.
| Type | Automatic (Torque Converter) |
| Service Items | ['Fluid change', 'Filter replacement', 'Pan inspection', 'Solenoid testing', 'Road test'] |
All automatics rely on friction clutch packs to engage gear sets. Wear is the primary failure mode.
Symptoms: Slip in specific gears, burning smell, delayed engagement
Electronic solenoids control hydraulic pressure to clutch packs. Wear or failure causes shift issues.
Symptoms: Harsh shifts, limp mode, specific gear loss
The torque converter transmits engine power to the transmission and provides TCC lockup for fuel economy.
Symptoms: Shudder at cruise, P0741, converter noise
