BMW 5 Series 7 Series Automatic Transmission 5-Speed 5HP-24 Tag 10667T Remanufactured

Description

Dependable highway towing power and zero shift flare return to your luxury BMW sedan. This BMW 5HP-24 Transmission Tag 10667T provides exact calibration matching for select E39 540i and E38 740i models. You must replace the cooler bypass thermostat and run an adaptation reset sequence before completing road verification tests.

Solid A380 die-cast aluminum forms the bellhousing and main gear case, inspected with magnetic particle dye after abrasive shot blasting. Hardened planetary carrier pins resist high shear loads from performance V8 torque. Upgraded A-clutch drums feature reinforced retaining walls to eliminate the common factory blowout failure. High-energy clutch frictions, Kolene steel reaction plates, and renewed pump bushings fill the housing. The complete assembly weighs 212 lbs dry and ships in a sturdy 38 by 26 by 24 inch crate.

Key Features of ZF 5HP24

Independent German auto shops buy ZF 5HP24 units to prevent catastrophic drum fracture without paying steep local dealer pricing. This commercial remanufactured transmission provides smooth ratio stepping and rock-solid internal pressure regulation under intense summer heat.

• Reinforced A-clutch cylinder drum stops snap-ring groove blowout under sudden acceleration loads.
• Oversized pressure regulator sleeve restores hydraulic integrity to prevent internal circuit pressure spikes.
• Valve body vacuum testing proves twenty-two inches of mercury retention on every reamed spool bore.
• Balanced torque converter eliminates unwanted driveline shudder while shielding front pump gears from wear.
• Raybestos high-energy frictions resist high heat glaze during high-speed mountain climbs.
• Machined stator shaft support bushings maintain uninterrupted oil flow to the converter lockup clutch.
• Calibrated accumulator pistons cushion shift application to eliminate harsh drive engagement thumps.

Automated Dynamometer Certification Telemetry

Technicians strap every finished transmission to a SuperFlow dynamometer for cold and hot run testing. Telemetry shows main line pressures reaching 185 PSI in Drive and 245 PSI in Reverse at 1600 RPM. Electronic pressure control solenoids respond in under twenty-four milliseconds with zero spool valve binding. Calibrated vacuum tests show twenty-two inches of mercury hold on critical hydraulic circuits. The test software logs zero lockup clutch slippage under simulated uphill load profiles. Thermal sensors confirm normal fluid temperatures without seal degradation.

Field Assembly Rules Limitations

Seat the torque converter inward with three distinct clicks until the hub drops well past the bellhousing mating surface. Never force the transmission against the engine block using bellhousing bolts. Do not buy this factory-calibrated unit for turbo track racers, drift builds, or vehicles with altered final-drive differentials.

• Flush cooler lines with hot pressurized solvent to clear metallic clutch debris from previous failures.
• Fill with OEM Lifeguard 5 fluid until it spills from the check port at thirty-five degrees Celsius.
• Perform an electronic adaptation reset procedure using a BMW scan tool before road testing.

Warranty Terms Shipping Contents

This remanufactured assembly includes a nationwide 3-Year/100,000-Mile warranty covering mechanical breakages and hydraulic valve body failures. The reinforced wooden crate contains a balanced torque converter, step-by-step installation instructions, dynamometer test pass printout, cooler flush verification card, and a pre-paid core return freight bill for easy transport.
