8HP70 Overhaul Kit, new and ready to install. Fits the 8HP70. Ships fast from the USA.
This is the kit for the service ZF calls lifetime fill and most owners skip: a full pan, filter and fluid change on an 8HP70 or 8HP50 eight-speed. It is a drain-and-fill kit, not a rebuild overhaul set. In the box you get an aftermarket 13-bolt transmission pan with the filter built in, a new pan gasket, a set of 13 pan bolts, and seven 1-liter bottles of genuine ZF LifeguardFluid 8 (the fluid ships in a separate box). It suits BMW, Ram, Jeep and Dodge owners at 60,000 to 100,000 miles, anyone who bought a used vehicle with no service history, and anyone chasing a weeping pan or rough shifts on old, dark fluid.
On the 8HP the filter is molded into the plastic pan, so you cannot change the filter without changing the pan. The pan gasket is also the most common leak point on an aging unit. The fluid does more than lubricate. The mechatronic runs every clutch apply through solenoid-controlled pressure, and its adaptations assume fluid with the right friction properties. ZF's product data sheet for LifeguardFluid 8 says the fluid is not truly lifetime. ZF recommends a change at 150,000 km (about 93,000 miles), and sooner for vehicles that tow, run hot or have unknown history. It also states that only LifeguardFluid 8 or 9 may be used. This kit puts the correct ZF fluid in the box, so there is no guessing at the parts counter.
A fluid change is maintenance, not a cure for mechanical failure. If the unit already slips hard, refuses a gear or sets ratio faults, diagnose first with our ZF8HP common problems guide. If the leak is at the electrical connector rather than the gasket, see our Charger 8HP problems guide for the sleeve leak. A new pan will not stop that one. On BMWs, wetness near the transmission-side cooler line connections is a known separate leak covered in BMW's own bulletin.
The listing covers the ZF 8HP family, including the 8HP45Z, 845RE, 8HP50Z, 8HP51, 8HP70Z, 8HP75Z and 8HP76. The reference part number is 24118612901. The important check is the pan itself. ZF used more than one pan style, and this kit is the 13-bolt pan. Count the bolts around your pan before ordering. If yours has 21 bolts, this pan will not fit, and Ram and Jeep owners should look at our Mopar 8HP70 pan and filter kit instead. If you are unsure, send us your year and VIN, or browse the ZF 8HP collection.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. It is a service kit: a 13-bolt pan with a built-in filter, a gasket, 13 bolts and seven liters of ZF LifeguardFluid 8. It has no frictions or internal seals.
Count the bolts around the edge of your pan. This kit fits the 13-bolt style only. A 21-bolt pan needs a different kit.
It is enough for a pan drain and fill, which only replaces part of the total fluid. A unit that has been fully drained or rebuilt needs more, so order extra LifeguardFluid 8.
ZF's data sheet says only LifeguardFluid 8 or 9 may be used in these units. The included fluid is genuine ZF LifeguardFluid 8.
ZF recommends a change at 150,000 km (about 93,000 miles), and sooner for vehicles that tow, run hot or have unknown history. Many owners do it earlier, around 60,000 miles.
No. A leak at the electrical connector sleeve is a separate seal on the mechatronic. This kit fixes pan gasket leaks and renews the filter and fluid.
