Complete ZF 8HP70 overhaul kit with clutch frictions, gaskets, lip seals and shaft sealing rings for BMW, Jeep, Dodge, Jaguar and Land Rover 8-speeds.
If your Grand Cherokee, Durango, Charger, 300, BMW X5 or Jaguar XF has an 8-speed that has started slipping, flaring between gears or leaking from more than one place, and the unit is coming out for a teardown, this is the parts package for the rebuild. The kit (manufacturer number AHM-QMP-GN01896) carries new clutch friction plates plus the full gasket set, lip seals, O-rings and the shaft and drum sealing rings for the ZF 8HP70 and 8HP75, so one box covers the soft parts that get discarded when the case is opened.
The 8HP70 builds its eight forward ratios from four planetary gearsets controlled by five shift elements: two brakes (A and B) and three rotating clutches (C, D and E). Three elements are applied in every gear, and each upshift or downshift releases one and applies another. Every rotating clutch is fed through sealing rings on the shafts and drums, and every piston is sealed with rubber. When friction lining wears thin or a sealing ring loses its fit, apply pressure leaks off, the element slips during the overlap, and the transmission module keeps adding adaptation until it runs out of range. Renewing all frictions and every sealing ring at once is what brings the unit back to a known baseline instead of fixing one clutch while the next one is already tired.
An overhaul kit only fixes worn clutches and seals, so prove that is the problem first. Check the fluid level with the correct procedure before anything else; ZF sets the level with the engine running and the fluid between 30 and 50 C, and an 8HP that is a liter low will slip and shift harshly on its own. Pull the pan and look for lining material, not just dark fluid. Delayed engagement and firm shifts can also come from valve body bore wear in the mechatronic, which a clutch kit will not cure. Our ZF8HP common problems guide walks through separating mechatronic faults from clutch wear, and the ZF8HP rebuild cost breakdown shows where the money goes on a full overhaul.
This kit is listed for 2011-2016 BMW X3, 2015 X4, 2010-2016 X5, 2010-2014 X6, 2013-2016 Chrysler 300, 2013-2016 Dodge Charger and Durango, 2011-2016 Jeep Grand Cherokee 3.0, 3.6, 5.7 and 6.4L, 2010-2016 Jaguar XF and XJ, 2011-2014 Jaguar XK, 2014-2016 Land Rover Discovery, 2010-2016 Range Rover and 2013-2016 Maserati Ghibli and Quattroporte. That is a wide spread of engines and model years across two generations of the 8HP family, and plate counts and seal sizes are not identical in every version. Read the transmission code on the case tag, lay the old plates beside the new ones before soaking, and send us your year and VIN if anything looks off. Everything else we stock for this family is on the ZF 8HP collection page.
The kit does not include drums, the pump, the mechatronic or the torque converter. If the valve body shows bore wear or a solenoid tests weak, a remanufactured 8HP70 valve body with solenoids goes in at the same time. Close the unit with a new pan and filter; the 8HP70 aluminum pan with gasket fits the Chrysler applications. A dry, overhauled unit takes roughly 9 liters of Lifeguard 8 through the case fill plug, then the level is set at temperature. Clear adaptations and complete a learn drive before handing the vehicle back.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
The listing describes clutch friction plates, gaskets, seals, O-rings, lip seals and sealing rings. Steels are not listed, so reuse yours only if they are flat, unscored and not blued, or order steels separately.
The listing covers 2013-2016 Charger 3.6, 5.7, 6.2 and 6.4L with the ZF-based 8-speed. Confirm the transmission code on the case and compare the old plates to the kit before building.
No filter is listed. Order a pan and filter kit for your application so the unit is closed up with a fresh filter.
ZF Lifeguard 8. A dry, overhauled unit takes roughly 9 liters, filled through the case plug and leveled with the engine running at 30 to 50 C.
Yes. The old adaptation values were learned on worn clutches. Clear them with a scan tool and complete a learn drive so the module adapts to the new packs.
