Audi A6 A8 Automatic Transmission 5-Speed 5HP-24 Tag 10655T Remanufactured

Transferring 4.2L V8 engine torque to Quattro drive axles, the Audi A6 A8 automatic transmission 5-speed 5HP-24 Tag 10655T remanufactured gearbox delivers positive forward gear engagement without drum snap-ring failure. High line pressure spikes in original 5HP24 transmissions crack the forward clutch drum lip, causing sudden loss of first through fifth gears. This remanufactured transaxle features a reinforced alloy A-clutch drum, sleeved valve body regulator bores, and a remanufactured torque converter with upgraded lockup linings.

Technicians disassemble the entire gear train, replacing all friction discs and steel reaction plates with brand-new OEM-grade materials. The front transmission oil pump undergoes line-boring and receives a new bronze drive bushing, preventing converter hub galling and front pump seal leaks. Automated dyno testing verifies that solenoid apply pressures, line pressure rise, and gear ratios match the exact programming requirements of Tag 10655T.

Key Engineering Features of 5HP-24 Tag 10655T

- Tag 10655T Factory Ratio Verification: Verified internal gear ratios match specific Audi A6 and A8 V8 engine management software.
- Reinforced Heavy-Duty A-Clutch Drum: Upgraded drum cylinder eliminates snap-ring groove failure to permanently restore forward drive.
- Sleeved Valve Body Regulator Bores: Precision sleeves eliminate hydraulic leaks to deliver smooth upshifts and downshifts.
- Rebuilt Heavy-Duty Torque Converter: Features reinforced lockup clutch linings and furnace-brazed fins to handle V8 torque.
- Re-Bored Front Oil Pump Assembly: New bronze stator bushing and Viton front pump seal stop transmission oil leaks.
- 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.

Hydraulic Circuit Upgrades & Dyno Load Verification

Rebuilt to original ZF engineering tolerances, this 5-speed transaxle eliminates common hydraulic leaks that degrade shift smoothness.

- Vacuum decay testing across all valve body control ports confirms zero hydraulic pressure bleed-off before installation.
- Re-machined oil pump stator bushings prevent torque converter hub runout, eliminating front seal oil leaks and pump gear wear.
- Updated torque converter lockup seals eliminate highway RPM surge, keeping cruising RPM steady and lowering fuel consumption.

Chassis Mounting & Transmission Tag Verification

Specifically calibrated for Audi A6 and A8 vehicles carrying transmission tag 10655T, this Quattro transaxle requires verifying the stamped identification plate on the transmission casing.

Factory Warranty Terms & Maintenance Guidelines

- European repair specialists receive 3-Year or 100,000-mile parts warranty protection against internal mechanical and torque converter defects.
- Cores must be returned drained in the provided transport container within thirty days with matching tag code 10655T.

Thoroughly flush the radiator cooler circuit, install a new transmission oil pan filter, and fill with approved synthetic fluid meeting VW G 052 162 specifications. Check fluid level with vehicle level on a lift at 35 degrees Celsius.
