Used Transmission for Sale

    At Upgrade Automart, we perform a comprehensive series of tests on all our used car and truck transmissions to ensure they are in peak working condition before sale:

    Visual Inspection

    We carefully examine each transmission for leaks, cracks, or damage to the casing. Mounts, brackets, and connections are inspected, along with signs of wear, corrosion, or contamination.

    Fluid Inspection

    Our technicians check the transmission fluid for proper level, color, and cleanliness. We look for metal shavings, burnt smell, or debris that could indicate internal wear.

    Pressure Testing

    We measure hydraulic pressure at critical points to verify proper line pressure and ensure the torque converter is functioning correctly.

    Gear and Shift Test

    All gears and modes—park, reverse, drive, and lower gears—are checked for smooth engagement. We ensure there is no slipping, hesitation, or hard shifting.

    Torque Converter Check

    We test the torque converter for proper engagement and smooth operation, confirming it won’t cause overheating or shuddering.

    Leak Test

    Seals, gaskets, and fluid lines are thoroughly tested under pressure to ensure there are no leaks.

    Electrical & Sensor Diagnostics

    Modern transmission sensors, including vehicle speed, input/output speed sensors, and solenoids, are scanned and checked for error codes to guarantee proper electronic function.

    Endurance / Hot Test

    For rebuilt or remanufactured units, we run the transmission under load to check heat management and internal performance.
