ZF 6HP26 6HP28 Automatic Transmission Bushing Repair Kit For BMW 750i, 750Li & Jaguar XKR

A Transmission Bushing Repair Kit for the ZF 6HP26 and 6HP28

This is an automatic transmission bushing repair kit built for the ZF 6HP26 and 6HP28 transmissions, cross-referenced to part numbers 6HP26 and 6HP28 (MPN BACB12-359007), confirmed to fit the 2006-2014 BMW 750i and 750Li and the 2003-2012 Jaguar XKR. If your vehicle is shifting harshly, slipping between gears, or shuddering at certain speeds, worn valve body bushings inside the transmission are a common and often overlooked cause.

Why These Transmissions Develop Bushing Wear

The ZF 6HP26 and 6HP28 are six-speed automatic transmissions used across a range of performance and luxury vehicles, and inside the valve body, a set of bushings controls the precise movement of the shift solenoids that direct transmission fluid to engage each gear. Over tens of thousands of miles, these bushings wear and develop play, which lets fluid leak past where it shouldn't, leading to the harsh shifts, slipping, and hesitation that owners often mistake for a failing transmission needing full replacement. Because the wear happens gradually inside a sealed component, most drivers don't realize the bushings are the culprit until a technician opens up the valve body during diagnosis.

Compatibility

Confirmed to fit the 2006-2014 BMW 750i and 750Li, and the 2003-2012 Jaguar XKR, all of which use the ZF 6HP26 or 6HP28 transmission. Because these ZF transmissions were also used in other BMW, Jaguar, Land Rover, Audi, and Volkswagen models, this kit may fit additional vehicles built around the same transmission, but confirming your specific vehicle and transmission code, or sending your VIN, is the safest way to guarantee fitment before ordering.

Signs Your Transmission Valve Body Bushings Are Worn

Worn bushings inside a 6HP26 or 6HP28 valve body typically show up as harsh or delayed shifts, a shudder or vibration felt through the drivetrain at steady highway speeds, occasional slipping between gears under load, or a transmission that seems to hunt between gears more than it used to. Because these symptoms closely mimic a failing torque converter or worn clutch packs, a proper diagnosis before assuming the transmission needs a full rebuild can save significant repair cost.

Why Owners Choose a Bushing Kit Over a Full Rebuild

A full transmission rebuild or replacement is a major expense, and in many cases, the underlying cause of harsh or slipping shifts is nothing more than worn valve body bushings rather than damage to the transmission's internal clutches or gear sets. Replacing just the bushing kit addresses the actual point of wear directly, which is why many owners and independent transmission shops treat this repair as the first step before considering a more expensive rebuild.

Installation Notes

Installing this kit means removing the transmission valve body, replacing the worn bushings with the new ones included in the kit, and reassembling the valve body before reinstalling it in the transmission. Because this job requires removing the transmission pan and working inside the valve body itself, it's typically performed by an experienced technician or transmission specialist rather than as a driveway repair.
