Full overhaul set for the ZF 8HP65 (VAG 0D5): friction plates, steels, gaskets, shaft seals and O-rings for an Audi A4, A6, Q7 or Q8 rebuild.
An Audi with the eight-speed tiptronic that flares between gears under power, shudders as it locks up, or sits for a beat before it takes Drive on a cold morning is usually telling you the clutch packs and seals inside its ZF 8HP65 are worn out. This master rebuild kit, manufacturer part number ING-GN03924, is built for that unit, the VAG transmission code 0D5 fitted behind longitudinal engines in the Audi A4, A6, Q7, Q8, S4, S5, S6 and S8. It supplies the friction plates, steel plates, gaskets, shaft seals, lip seals and O-rings for a full bench overhaul, and the listing notes the 8HP65A variant shares the same internals.
Every ZF eight-speed builds its ratios from four planetary gear sets controlled by five shift elements: two brakes (A and B) and three rotating clutches (C, D and E). Each element is a stack of friction and steel plates squeezed by a hydraulic piston, and each piston depends on rubber seals to hold apply pressure. Over high mileage the friction lining glazes and thins, the pack clearance grows, and the seals harden with heat. The result is slower, softer apply that the transmission module tries to cover with adaptation until it runs out of room. This kit replaces the wear material and every rubber seal in one job, so the unit goes back together with fresh packs and a tight hydraulic circuit instead of a mix of new and tired parts.
Slip and harsh shifts on an 8HP are not always clutch wear. Valve body bore wear and leaks in the mechatronic connector sleeve also drop apply pressure, and those are cheaper fixes. Read the fault memory first: solenoid or electrical codes call for valve body diagnosis, not a clutch rebuild. Then check the fluid correctly, because these units have no dipstick and an underfilled pan starves the packs. If the fluid is burnt and the pan holds lining material, the packs are worn and an overhaul is the right call. Our ZF8HP rebuild cost guide lays out when a rebuild beats a used or exchange unit, and the ZF8HP common problems guide covers the faults that mimic clutch slip.
The listing specifies the ZF 8HP65 and 8HP65A, transmission code 0D5, in the Audi A4, A6, Q7, Q8, S4, S5, S6 and S8. Not every version of those cars uses this transmission; several Audi models also offered dual-clutch or other automatics depending on engine and year. Read the transmission code from your vehicle data sticker or ask your dealer to decode the VIN, then confirm it says 0D5 before ordering. If you are unsure, send us your year and VIN and we will check it. When you strip the unit, lay the old plates out in order and compare plate counts and thicknesses to the kit before you build. Other ZF eight-speed parts, including kits for BMW and Chrysler versions, are on our ZF 8HP collection page.
This is soft parts and clutches only. It does not include the mechatronic, solenoids, pump, planetaries or the torque converter, so inspect drums, bushings, thrust washers and the pump during teardown and replace anything worn. Clean and air-check each clutch drum, soak the new frictions in fresh fluid before stacking them, and measure every pack's clearance with a dial indicator rather than trusting stack height. Renew the mechatronic sleeve seals while the unit is apart.
ZF specifies Lifeguard 8 fluid for this family; a product sold for ZF 8HP use such as Liqui Moly Top Tec ATF 1950 is another option, and an overhauled dry unit takes about 9 liters per Sonnax's fill guide. Fill through the case plug, then set the final level hot with the engine running. If you also work on BMW or Chrysler eight-speeds, the 8HP70/8HP75 master kit covers those units.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
It is listed for the ZF 8HP65 and 8HP65A, code 0D5, in the A4, A6, Q7, Q8, S4, S5, S6 and S8. Confirm your transmission code reads 0D5 on the vehicle data sticker, or send us your year and VIN.
Friction plates, steel plates, case and pan gaskets, shaft seals, lip seals and the O-ring set. It does not include the mechatronic, solenoids, pump, planetaries or torque converter.
No. Electrical or solenoid codes come from the valve body side. Diagnose those separately; this kit addresses worn clutches and hardened seals.
Sonnax lists about 9 liters for a dry, overhauled ZF eight-speed. Fill through the case plug and set the final level hot with the engine running.
Inspect the drums, bushings, thrust washers and pump, and replace the mechatronic sleeve seals. Have the torque converter checked if the old fluid was burnt.
