Audi A6 A8 Automatic Transmission 5-Speed 5HP-24 Tag 10656T Remanufactured

Description

Eliminating forward gear engagement loss on 4.2L V8 sedans, the Audi A6 A8 automatic transmission 5-speed 5HP-24 Tag 10656T remanufactured gearbox restores positive clutch clamping through a reinforced steel A-clutch drum. Original factory aluminum forward clutch cylinders crack along the snap-ring groove under heavy V8 acceleration, causing the transmission to rev freely in Drive while reverse gear continues to function. This remanufactured unit replaces the weak factory casting with an upgraded heavy-duty alloy drum, paired with re-machined valve body regulator bores and a rebuilt torque converter.

Hydraulic line pressure spikes that crack original clutch drums are eliminated by installing an oversized pressure regulator valve sleeve inside the aluminum valve body casting. Technicians inspect the Quattro all-wheel-drive center differential, resetting pinion gear preload with precision shims to eliminate gear whine during high-speed highway travel. Every unit runs on automated load dynos through multiple warm-up cycles, confirming that fluid pressure and shift timing match the factory requirements of Tag 10656T.

Key Engineering Updates on 5HP-24 Tag 10656T

• Reinforced Heavy-Duty A-Clutch Drum: Upgraded drum cylinder eliminates snap-ring groove failure to permanently restore forward drive.
• Tag 10656T V8 Ratio Verification: Internal planetary gearsets and differential ring gear match 4.2L V8 engine control computers.
• Oversized Main Pressure Regulator Valve: Machined valve body bore stops pressure spikes that shatter internal clutch drums.
• Rebuilt Heavy-Duty Torque Converter: Features reinforced lockup clutch linings and furnace-brazed fins to handle V8 torque.
• Integrated Quattro Center Differential: Precision-shimmed center differential provides positive all-wheel-drive power delivery.
• Multi-Channel Dynamic Load Dyno Testing: Checks stall speed, line pressure rise, and gear ratio transitions across all forward gears.

A-Clutch Drum Reinforcement & Pressure Regulation

Engineered for high-output German V8 executive sedans, this heavy-duty 5-speed transmission delivers factory-quiet cruising and firm gear engagement.

• Upgraded A-clutch drum metallurgy eliminates the primary mechanical failure mode of ZF 5HP24 transmissions on V8 platforms.
• Machined pressure regulator bores eliminate line pressure spikes, protecting internal clutch drums from premature stress cracking.
• Pre-tested shift and pressure solenoids ensure consistent gear transitions in automatic drive mode and manual Tiptronic control.

Transmission Tag Identification & Final Drive Matching

Calibrated specifically for Audi A6 and A8 models specifying tag code 10656T on the casing data plate, this Quattro transaxle integrates with factory driveshafts.

Commercial Warranty & Installation Guidelines

• Commercial European service shops receive 3-Year or 100,000-mile parts warranty protection against internal component failure.
• Core credit requires return of an identical rebuildable 5HP-24 core with tag 10656T inside the original shipping crate.

Flush the radiator oil cooler with pressurized solvent to remove trapped metal particles, replace the pan filter, and fill the transmission with approved synthetic fluid meeting VW G 052 162 standards. Check fluid level through the pan check plug between 35 and 45 degrees Celsius.
