BMW 5 Series 7 Series Automatic Transmission 5-Speed 5HP-30 Tag 10679T Remanufactured

Strict OEM core qualification standards govern every rebuild step on this assembly. This 5HP-30 tag 10679T remanufactured transmission provides precise gear stepping for select BMW 5 Series and 7 Series vehicles. You must perform a complete chemical cooler flush and clear transmission adaptives before putting the car into service to protect internal hydraulic controls.

Shot-peened 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 and V12 engines. Upgraded 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 245 lbs dry and ships in a sturdy 40 by 28 by 26 inch crate.

Key Features of ZF 5HP30

Automotive repair shops buy ZF 5HP30 transmission units to stop internal pressure decay without paying excessive local dealership pricing. This commercial remanufactured transmission assembly ensures positive power transfer and solid pressure containment for your BMW 7 Series transmission replacement project.

- Reinforced 5HP-30 tag 10679T transmission drum stops snap-ring channel blowout under hard vehicle acceleration.
- Oversized pressure regulator valve sleeve prevents internal hydraulic pressure spikes inside the valve body.
- Valve body vacuum testing proves twenty-two inches of mercury retention on every reamed spool bore.
- Balanced torque converter stops driveline shudder while protecting front pump drive gears from premature wear.
- Raybestos high-energy frictions resist high heat glaze during high-speed summer highway driving.
- Precision stator shaft support bushings maintain constant fluid supply to the converter lockup clutch.
- Calibrated accumulator pistons cushion forward gear apply to eliminate harsh transmission engagement thumps.

Automated Dynamometer Certification Telemetry Data

Technicians strap every finished transmission to a SuperFlow dynamometer for cold and hot run testing. Telemetry confirms main line pressures reaching 188 PSI in Drive and 255 PSI in Reverse at 1600 RPM. Electronic pressure control solenoids react within twenty 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 Application Limits

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 Shell LA2634 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.
