8HP45 Valve Body 2014, used and ready to install. Fits the 8HP45. Ships fast from the USA.
If your 2014 BMW, Jaguar, Land Rover, Jeep Grand Cherokee, Ram 1500 or 845RE-badged Charger, Challenger or 300 is shifting harsh, slipping between gears, or has thrown a pressure or solenoid code and dropped into limp mode, the ZF 8HP45 valve body under the pan is the usual cause. This listing is a used OEM unit pulled specifically from a 2014-model-year vehicle, reference number 8601661, tested and ready to bolt in rather than a reman core you have to wait on. Ordering the right revision matters more than it sounds: the 8HP45 went through several internal updates over its production run, and a valve body built for a different year can leave you with the same shift complaints you started with even though the part looks identical on the shelf.
The 8HP45 is the lower-torque member of ZF's eight-speed family, sized for the four- and six-cylinder engines it backs rather than the V8 and diesel applications that use the heavier 8HP70 and 8HP90 castings. Its valve body carries the shift and pressure-control solenoids the transmission control module fires to move spool valves through precision bores, routing line pressure to the correct clutch pack for each of the eight forward gears. On a 2014 unit specifically, that routing has to match the TCU calibration installed that model year, which is why the exact production year on a used part is not a minor detail.
Before replacing the valve body, rule out a fluid level or a single failed solenoid, since both can mimic a worn valve body on a scan tool. Our ZF8HP common problems and fixes guide covers the diagnostic order BMW's own enhanced technical support process follows, and our pressure control solenoid symptoms guide walks through the specific pressure-trace test that separates a solenoid fault from worn valve body bores so you are not replacing the wrong part.
This unit was pulled from a 2014 vehicle equipped with the ZF 8HP45, OEM reference 8601661. The 8HP45 does not interchange with the 8HP70 or 8HP90 used in higher-output versions of the same vehicle lines, and even within the 8HP45 itself, confirm your transmission code and connector style against the listing photos before ordering - the safest match is your year plus VIN, since running changes inside a single model year are common on this platform. The ZF 8HP parts collection carries other years and the solenoid-equipped version if your 2014 needs a different revision than this one.
Drain the fluid, drop the pan, disconnect the internal harness and pull the old unit before this one goes in - leftover debris from a worn valve body is the most common cause of a quick comeback on this job. Torque the mounting bolts in the factory crossing pattern so the separator plate and check balls seat correctly, refill with ZF LifeGuard 8 ATF only, and replace the filter and pan gasket at the same time rather than reusing the old ones. Finish with the transmission control module's adaptive relearn through a mix of light and moderate throttle shifts, and pair the job with a fresh TCC solenoid if converter lock-up shudder was part of the original complaint.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Used OEM, pulled from a 2014 vehicle, reference number 8601661, tested and ready to install.
The 8HP45 went through running changes across its production, and a valve body built for a different year can carry a different internal calibration that will not fully resolve your shift complaint even though it bolts in.
2014 BMW 3 Series and 5 Series, Jaguar XF and XJ, Land Rover Range Rover Sport and Evoque, and under the 845RE badge the Jeep Grand Cherokee, Ram 1500, and 3.6L Pentastar Charger, Challenger and 300.
Harsh or flared shifts, slipping once warmed up, delayed engagement into drive, or limp mode with a stored pressure or solenoid code.
