5HP24 Valve Body 1998, new other (see details) and ready to install. Fits the 5HP24. Ships fast from the USA.
A 1998 BMW, Range Rover P38a or Jaguar running the ZF 5HP24 that feels like it slips into neutral at a stop once it's warmed up, chatters taking off from a stop, or has thrown a P0731 or Jaguar P1722 code almost always has a hydraulic fault in the upper valve body rather than a bad clutch pack. This is a ready-to-install 5HP24 valve body matched to the 1998 production run, so the fix is a known-good hydraulic section instead of a guess.
Transmission Digest's technical write-up on this unit traces the complaint to the F-clutch circuit in the upper valve body: sustained high line pressure can crack that section of the casting, and because the F clutch is what's applied in park, reverse, neutral and manual low, the leak drains F-clutch oil specifically. The park/neutral feed runs through the F-clutch valve while reverse is fed separately through the reverse valve, which is exactly why a car with this fault still backs up fine even while it feels like it's in neutral going forward.
Because this fault lives in the F-clutch circuit, it hits first gear and first gear only - a scan that comes back with a ratio-error code isolated to first, normal reverse operation, and no complaints in 2nd through 5th is the signature of this valve body rather than a worn clutch or a torque converter problem. If the vehicle is a Range Rover P38a and the actual complaint is a late shift or a felt-neutral condition at highway speed instead of at a stop, check for Land Rover TSB LTB00080 first - it describes a coolant-corrosion-inhibitor depletion that restricts the transmission cooler and pushes the TCM into an overheat shift strategy, a cooling fix rather than a valve body replacement.
This listing is built for the 5HP24 as installed in 1998 model-year BMW, Range Rover P38a and Jaguar applications. ZF revised this valve body's casting more than once across the 5HP24's run - Transmission Digest lists casting 1058 427 059 and the later 1058 427 068, each paired with its own pressure-regulator-valve part number - so confirm your casting marks against the listing photos, or send your year, make and VIN so we can match the exact revision. If you need to verify which ZF unit is actually in the car first, our ZF transmission identification guide explains how to read the stucklisten tag ZF uses across this family.
Change the pan, filter and fluid at the same time as the valve body so contamination from the old unit doesn't pass into the new one - ZF's LifeguardFluid 5 datasheet names this as the only approved fluid for 5HP-series transmissions, with no substitute listed. Torque the valve body bolts in the correct sequence rather than working corner to corner. A 1998-production unit is a good match for our 5HP24 solenoid kit, 1997-2001 if a solenoid fault is part of the complaint, and a 5HP24 planetary, 1998-2004 or 5HP24 clutch drum, 1998-2004 if you're already into the unit for other wear items at the same mileage.

On the ZF 5HP24, Transmission Digest documents high line pressure cracking the upper valve body's F-clutch circuit, which bleeds off F-clutch oil. Since the F clutch is what applies in park, reverse, neutral and manual low, the leak shows up as a neutral-feeling stop or takeoff chatter once the unit is hot.
Gear-ratio-error-in-first. The same cracked F-clutch circuit only feeds the A clutch's first-gear application, so the code is isolated to first gear while 2nd through 5th and reverse stay normal.
Check Land Rover TSB LTB00080 first. It describes depleted coolant corrosion inhibitor restricting the transmission cooler, which puts the TCM into an overheat-protection shift strategy that can feel similar but is a cooling-system issue, not a valve body fault.
It's built for 1998 model-year BMW, Range Rover P38a and Jaguar applications, but ZF ran more than one casting revision during this production window, so match your casting marks against the photos or send your VIN to confirm.
ZF LifeguardFluid 5 - ZF's own datasheet lists it as the required fluid for 5HP-series transmissions including the 5HP24, with no approved substitute.
A filter and pan gasket kit at minimum. If other wear symptoms are present, a year-matched solenoid kit, planetary or clutch drum for this production window is worth doing alongside the valve body rather than as a separate job later.
