Audi A4 A6 Automatic Transmission 5-Speed 5HP19FL Tag 10684T Remanufactured

Locking up internal multi-plate friction clutches under load, the Audi A4 A6 automatic transmission 5-speed 5HP19FL Tag 10684T remanufactured gearbox transfers smooth V6 engine power to front drive axles without slipping. Worn valve body bores and degraded torque converter clutch seals cause RPM surging on the highway and rough clunking downshifts when slowing to a stop. This remanufactured transmission features a remanufactured torque converter with upgraded seals, precision-machined valve body passages, and reinforced internal clutch drums.

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. Every unit undergoes automated dyno testing to verify that solenoid apply pressures, line pressure rise, and gear ratios match the exact programming requirements of tag code 10684T.

Key Engineering Features of 5HP19FL Tag 10684T

- Tag 10684T Factory Ratio Verification: Verified internal gear ratios match specific Audi A4 and A6 engine management software.
- Upgraded Torque Converter Lockup Piston: Reinforced friction lining and high-temperature seal design prevent P0741 converter slippage.
- Sleeved Valve Body Regulator Bores: Precision sleeves eliminate hydraulic leaks to deliver smooth upshifts and downshifts.
- Re-Bored Front Oil Pump Assembly: New bronze stator bushing and Viton front pump seal stop transmission oil leaks.
- Brand New OEM Friction Plates: High-energy friction material throughout all forward and reverse clutch packs ensures full torque holding.
- Multi-Channel Dynamic Load Dyno Testing: Checks stall speed, line pressure rise, and gear ratio transitions across all five forward gears.
- Complete Viton Gasket and Seal Overhaul: High-temperature seals prevent external fluid weeping and internal cross-circuit pressure loss.

Valve Body Vacuum Testing & Fluid Hydraulic Control

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.

Vehicle Fitment & Cooler Line Flushing Requirements

Built for Audi A4 and A6 passenger sedans and wagons carrying green identification tag 10684T, this front-wheel-drive unit bolts to factory engine blocks and subframes.
