8HP70 Valve Body with Solenoids, Remanufactured

A remanufactured ZF eight-speed valve body supplied complete with its solenoid set already installed, so you are not transferring solenoids off a core. Each unit is disassembled, cleaned, inspected, calibrated and function tested before it ships, which is the part that matters on an 8HP: the bores wear, and a valve body that only got a wash and a new solenoid pack still hangs shifts.

Covers the ZF 8HP45, 8HP55, 8HP70 and 8HP90 eight-speed automatics used across BMW, Audi, Land Rover and Jaguar. Verify the ZF code stamped on your unit and the valve body casting number before ordering, since the family shares an outline but not the calibration. On most of these cars the valve body and mechatronic unit come out as an assembly once the pan is off and the internal harness sleeve is released.

Go to a valve body when the car sets pressure or ratio codes, hangs between gears, slams the 2-3 or 4-5, will not lock the converter, or drops into limp home with no mechanical noise from the unit. Before you install one, flush the cooler and lines, replace the pan and filter, and change the mechatronic sleeve seal while access is open. Refill with the correct ZF Lifeguard spec fluid and set level by the temperature and overflow procedure, then clear adaptives so the TCU relearns against the new body instead of the old one.
