OEM Remanufactured Automatic Transmission Assembly
Gear Ratio Conversion & Smooth Shift Programming

OEM Low-Mileage & Remanufactured Automatic Transmissions

Eliminate harsh or slipping gear changes, burnt ATF fluid smell, and transmission fault codes with our comprehensively rebuilt and low-mileage OEM replacement transmissions.

The automatic transmission converts engine torque into variable drive ratios through a hydraulically controlled planetary gear set, torque converter clutch, and electronically modulated valve body shift solenoids. Burnt ATF fluid, worn friction clutch packs, faulty pressure solenoids, or failed torque converter lock-up clutches cause slipping during upshifts, delayed engagement, shuddering at highway speeds, and P0700 DTC fault codes. Our replacement transmissions are fully tested and include fresh gaskets, solenoids, and sensors.

Transmission slip feels like sudden RPM flare during an upshift where engine revs surge momentarily without proportional vehicle acceleration, similar to a slipping clutch pedal in a manual car.

Modern automatic transmissions communicate with a Transmission Control Module (TCM). On some vehicles, the TCM must be flashed with updated calibration software to properly adapt shift points to the new transmission internal components.

Torque converter shudder at 40–55 mph is caused by slipping lock-up clutch friction material inside the torque converter, often due to degraded ATF fluid. A converter clutch that fails to fully lock transmits vibration as a steady shudder.

Yes. Metal debris from a failed transmission pumps into the torque converter. Installing a replacement transmission with a contaminated old torque converter will damage the new unit within weeks.

With regular ATF fluid service every 30,000–60,000 miles, most modern automatic transmissions last 150,000–200,000 miles. Neglected fluid service typically leads to early failure around 80,000–100,000 miles.
