BMW 5 Series 7 Series Automatic Transmission 5-Speed 5HP-30 Tag 10676T Remanufactured

Description

Dependable V12 torque handling and crisp ratio staging return to your flagship German sedan. This ZF 5HP-30 tag 10676T remanufactured transmission provides exact hydraulic calibration for select BMW 5 Series and 7 Series models. You must replace the external cooler thermostat and perform a scan-tool adaptation reset before putting the vehicle into service.

Dense A380 die-cast aluminum forms the heavy-duty transmission housing, stripped of corrosion and tested for stress cracks using non-destructive dye penetrant. Massive planetary carrier gear sets absorb tremendous big-block torque without tooth deflection. We install updated valve body separator plates, high-capacity Raybestos clutch packs, and Kolene treated reaction steels. Heavy-duty stator support bushings prevent internal fluid leakage. The dry transmission weighs 245 lbs and ships inside a 40 by 28 by 26 inch crate.

Key Features of ZF 5HP30

Repair shops buy ZF 5HP30 transmission units to restore factory ratio staging without paying prohibitive dealer parts pricing. This commercial remanufactured transmission assembly delivers dependable power transfer for BMW 750i remanufactured transmission projects.

• Reinforced 5HP-30 tag 10676T transmission clutch drums handle heavy V12 engine torque output.
• CNC-machined pressure regulator valve sleeve prevents dangerous line pressure spikes in valve circuits.
• Valve body hydro-testing confirms twenty-two inches of mercury vacuum retention across all spool bores.
• Balanced heavy-duty torque converter eliminates vibration while protecting the front oil pump gears.
• Raybestos high-energy friction plates resist thermal glaze under continuous high-speed Autobahn driving.
• Precision stator shaft support bushings maintain uninterrupted oil flow to the converter clutch circuit.
• Updated accumulator springs soften forward clutch application to eliminate abrupt gear engagement thumps.

SuperFlow Bench Dynamometer Telemetry Data

Every completed 5HP30 gearbox undergoes rigorous hot and cold diagnostic runs on a SuperFlow transmission dynamometer. Telemetry logs confirm main line pressures reaching 190 PSI in Drive and 255 PSI in Reverse at 1600 RPM. Shift solenoids show sharp mechanical response times within twenty milliseconds under live electronic control tests. Valve body hydraulic circuits sustain twenty-one inches of mercury vacuum under static bench drawdown. Dyno sensors log zero converter clutch slip under maximum simulated load. Fluid temperatures hold stable at 180 degrees Fahrenheit.

Field Installation Guidelines Negative Filter

Seat the heavy torque converter inward with three distinct clicks until the hub recedes well past the front bellhousing plane. Ensure engine block alignment dowels are clean before tightening bellhousing bolts. Do not buy this factory-spec unit for twin-turbo custom engine builds, drift cars, or nitrous drag racing.

• Flush vehicle transmission cooler lines with hot chemical solvent to clear old bronze particulate.
• Fill with OEM Shell LA2634 fluid until fluid trickles from the check plug at forty degrees Celsius.
• Reset transmission adaptation registers using professional diagnostic tools prior to road testing.
