About this product

This is a used, factory 8HP70 valve body assembly with the oil pump, removed from a 2014 BMW 750Li with 77,107 miles and inspected as working. It is listed for the V8 BMWs that use the 8HP70: the 2013-2019 550i, 650i and 750i. If your car whines with engine speed in Park, takes a long time to engage Drive or Reverse, or slips in every gear once warm, the pressure supply is the suspect, and replacing the pump together with the hydraulic control it feeds is a common way to put a known-good pressure system back in the case.

What the pump and valve body do in an 8HP70

ZF moved the 8HP pump off the input axis. Instead of riding on the converter hub, a vane pump sits to the side and is driven by a chain from a shaft that turns with the converter impeller, as laid out in ZF's own pump drive patent. Everything downstream depends on that output: the pressure regulator turns pump flow into line pressure, which feeds the converter, the converter clutch and the five shift elements, while the valve body and its solenoids meter that pressure to each clutch and brake. A pump that has lost volume makes every gear weak at once, while a worn valve body bore tends to upset specific shifts.

Symptoms

How to confirm before buying

True pump failure on the 8HP is uncommon, so prove it first. Low fluid is the number one false alarm, especially after a previous fluid change done without the correct temperature-controlled level check. Verify the level, look for a torn O-ring or a suction-side air leak, and compare slip across all shift elements in live data. Our ZF8HP pump failure symptoms guide goes through each test and the faults that get misdiagnosed as a pump, and the ZF 8HP transmission guide covers how the system fits together.

Fitment

The donor was a 2014 750Li, and the listing covers the 2013-2019 BMW 550i, 650i and 750i with the 8HP70. The tag carries part numbers 1087128603, 1087427174, 0260550074 and 0501327294, with interchange number 400-62394. Match those numbers to the ones on your own unit before ordering. BMW used several 8HP variants in these chassis, and a six-cylinder or diesel car may not share this calibration or hardware. If you are not sure, send us the year and VIN. For other ZF 8-speed parts, browse the ZF 8HP collection; if you only need a bare pump, the 8HP70 pump for 2014-2019 and the ZF8HP pump are separate listings.

Install notes

If the unit has already slipped hard, the clutches may be damaged too; the 8HP70 master rebuild kit covers the seals and soft parts for a full overhaul.

8HP70 Pump: common questions

Is this a bare oil pump?

No. It is a used OEM 8HP70 valve body assembly with the oil pump, removed together from a 2014 BMW 750Li with 77,107 miles. If you only need the pump, see our separate pump listings.

Which cars does it fit?

It is listed for 2013-2019 BMW 550i, 650i and 750i with the 8HP70. Match part numbers 1087128603, 1087427174, 0260550074 and 0501327294 to your unit, or send us your year and VIN.

Will it need programming?

Plan on it. A used control assembly from a different car generally has to be programmed to your vehicle, and the transmission adaptations must be reset and relearned with a capable scan tool.

What fluid does it take?

ZF LifeguardFluid 8. Set the level with the engine running and the fluid between 30 and 50 C, filling until it just runs out of the fill hole.

How do I know the pump is really the problem?

Check the fluid level correctly first, then listen for a whine that follows engine rpm in Park and compare slip across all shift elements. Low fluid and suction leaks are far more common than a failed pump.
