BMW 5 Series 7 Series Automatic Transmission 5-Speed 5HP-24 Tag 10666T Remanufactured

Slot this BMW 5HP-24 Remanufactured Transmission 10666T straight into your rear-wheel-drive luxury bay. Engineered for specific production split BMW 5 Series and 7 Series chassis, this five-speed unit restores crisp forward engagement. You must replace the transmission cooler thermal bypass valve and reset computer shift adaptives to maintain factory line pressure control.

Shot-peened high-grade aluminum makes up the external casing, stripped of road corrosion and checked for hairline bellhousing stress fractures. Inside, forged steel planetary gears handle heavy luxury sedan curb weight without tooth spalling. The front pump assembly features fresh babbit bushings and a micro-polished seal collar to block leaks. Heavy-duty Raybestos friction packs and precision Kolene steel plates fill every clutch drum. The dry transmission weighs 212 lbs and ships in a 38 by 26 by 24 inch crate.

Key Features of ZF 5HP24

Professional mechanics buy ZF 5HP24 transmissions to eradicate harsh gear hunting without facing steep dealer part pricing. This commercial remanufactured transmission supplies reliable torque capacity and restored shift quality for aging executive saloons.

- Updated A-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.

Dynamometer Diagnostic Test Results

Technicians load every completed transmission onto an AIDCO test stand to assess hydraulic pressures across all gears. Main line pressure records 180 PSI in Drive and 240 PSI in Reverse at 1600 RPM. Shift solenoid cycles execute within twenty-two milliseconds under electronic valve modulation tests. Valve body hydro-testing confirms a vacuum hold of twenty-one inches of mercury on worn factory ports. Dynamometer sensors record zero converter clutch slip under simulated hill climbs. Hot fluid testing at 180 degrees Fahrenheit confirms pump flow integrity under heavy mechanical load.

Installation Advice Application Limitations

Turn and seat the torque converter through three distinct clicks to avoid crushing the internal oil pump gears. Never draw the bellhousing to the engine block with bolts before ensuring full dowel pin seating. Do not buy this OEM-spec transmission for track-drift setups, nitrous-fed engines, or aftermarket manual valve-body conversions.

- Flush radiator heat exchangers with dedicated transmission cleaner to remove metal contamination.
- Fill with ZF Lifeguard fluid while monitoring oil sump temperatures with professional diagnostics.
- Reset electronic transmission adaptation values using factory dealer software before initial street driving.

Warranty Protection Package Contents
