BMW 5 Series 7 Series Automatic Transmission 5-Speed 5HP-30 Tag 10680T Remanufactured

Virgin shot-peened A380 aluminum forms the foundation of this reinforced transmission assembly. This remanufactured 5HP-30 tag 10680T transmission delivers restored hydraulic line pressure for select BMW 5 Series and 7 Series vehicles. You must replace the transmission cooler bypass thermostat and reset computer shift adaptives to maintain factory gear modulation under load.

Clean shot-peened A380 die-cast aluminum encloses the heavy gear train, inspected for hairline bellhousing fissures using fluorescent dye testing. High-strength forged planet gears transfer massive V8 and V12 power without tooth spalling. Rebuilt internals include reinforced clutch drums with thickened snap-ring walls, Kolene reaction steels, and Raybestos high-energy friction packs. Renewed front pump stator bushings prevent circuit cross-leaks. The dry gearbox weighs 245 lbs and ships inside a 40 by 28 by 26 inch crate.

Key Features of ZF 5HP30

Professional mechanics buy ZF 5HP30 transmissions to eliminate harsh gear hunting without facing steep dealer part pricing. This commercial remanufactured transmission assembly supplies reliable torque capacity and restored shift quality for BMW 750i transmission replacement projects.

- Updated clutch housing features thickened snap-ring walls to prevent catastrophic structural rupture.
- Re-machined pressure regulator valve bore eliminates line pressure spikes that crack clutch cylinders.
- Vacuum testing guarantees minimum twenty-two inches of mercury seal across all control circuits.
- Balanced remanufactured torque converter prevents front stator bushing galling under heavy highway acceleration.
- High-energy friction discs prevent thermal breakdown during stop-and-go mountain grade driving.
- New output shaft seal eliminates rear fluid leaks near the driveshaft guibo coupler.
- Refurbished solenoid group ensures factory response timing across all five forward gear ratios.

AIDCO Bench Dynamometer Pressure Metrics

Technicians secure each remanufactured transmission to an AIDCO test bench to verify internal line pressure across every gear ratio. Pressure readings log 188 PSI in Drive and 255 PSI in Reverse at 1600 RPM. Electronic shift solenoids actuate valve passages within twenty-two milliseconds under live computer diagnostics. Hydro-testing proves a steady vacuum hold of twenty-one inches of mercury on all reamed valve body ports. Dyno computer sensors verify zero converter clutch slip under loaded hill climb programs. Fluid testing at 180 degrees Fahrenheit confirms proper hydraulic flow without case leaks.

Installation Directives Field Application Limits

Turn and push the torque converter until you verify three distinct clicks into the pump drive gear teeth. Avoid drawing the bellhousing against the engine block with bolts before dowels seat. Do not buy this factory spec transmission for high-boost turbochargers, nitrous setups, or drift competition.

- Flush chassis radiator heat exchangers with dedicated solvent to remove suspended metal dust.
- Fill with Shell LA2634 fluid while monitoring sump temperature with factory diagnostic tools.
- Reset transmission shift adaptation data using a diagnostic scan tool before highway driving.

Nationwide Warranty Freight Manifest Details

This remanufactured assembly carries a nationwide 3-Year/100,000-Mile warranty covering mechanical damage and valve body pressure loss. Your delivery crate contains a balanced torque converter, technician installation instructions, dyno pressure test certification, cooler flush tracking sheet, and a pre-paid freight bill of lading for prompt core return pickup.
