5HP24 Solenoid Kit 1997-2003, remanufactured and ready to install. Fits the 5HP24. Ships fast from the USA.
A 1997-2003 BMW 540i with the automatic that slurs its upshifts, kicks hard into Drive, or suddenly holds one gear with the transmission light on is a common search, and worn solenoids are a frequent cause. This is a remanufactured eight-piece solenoid set for the ZF 5HP24 five-speed behind the 4.4L V8 in the E39 540i sedan and Touring, so the entire electrical side of the valve body can be refreshed in a single repair.
ZF launched the 5HP24 in 1996 for longitudinal V8 cars, and the E39 540i is one of its best-known homes. The transmission module reads throttle, road speed and engine load, then fires on/off solenoids to select which shift valves are open and pulses regulating solenoids to set the oil pressure feeding each clutch pack. That pressure control is what separates a crisp 540i shift from a sloppy one. A converter lockup circuit rounds out the group. Of the eight parts shown, four are small switching units with black connectors, one is a larger regulator wearing a green plug, and three are regulators with machined aluminum housings. As coils age and the pintle seats wear, pressure stops tracking what the module commands.
Pull codes with a scanner that talks to the BMW transmission module, not just the engine. Next, check each solenoid's resistance at the case connector using the method in our multimeter solenoid test guide; a coil reading open or far off its siblings is a clear answer. Pay attention to how the problem feels, too. Our article on shift flare versus slip explains why a flare that comes and goes points to control pressure while a steady slip points to worn clutches. Transmission Digest has also documented a cracked upper valve body on the 5HP24 that causes a neutral feeling at a stop with only a first-gear ratio fault; if that matches, a 1998 5HP24 valve body is the right fix rather than solenoids alone.
This listing is for the BMW 540i 4.4L from 1997 through 2003. ZF application lists place the E39 540i automatic on the 5HP24, but they also show some E39 540i cars with the larger 5HP30, so read the tag on the side of your transmission case before ordering. The same set cross-references to interchange number 13200B. Compare the plug colors and body shapes of your old solenoids with the photo, or send your year and VIN and we will confirm. Other 5HP24 solenoid kits for different vehicles and years are listed separately in our store.
With the 540i on a lift, drain the pan, remove the pan and filter, then unbolt the valve body while keeping the bolts sorted by length. Map each solenoid's location before removal so every switching and regulating unit goes back to its own bore. Install the new parts with fresh O-rings coated in clean fluid and inspect the internal harness and case connector seal, a known seep point on older BMWs. Refill with ZF LifeguardFluid 5 or the fluid called out on your service label and check level at operating temperature through the fill plug; our drain and fill walkthrough covers the hot-level check. Reset adaptations when you finish. If the unit has high mileage and dark fluid, pairing this kit with a 5HP24 overhaul kit saves pulling the transmission twice.

No. It is for the automatic only, the ZF 5HP24 five-speed. Some E39 540i automatics are also listed with the 5HP30, so check the ZF tag on your case before ordering.
The E38 740i also used the 5HP24, but this listing is titled for the 540i 4.4L. Send us your year and VIN and we will confirm before you order.
Eight remanufactured solenoids, as shown in the photo: compact switching solenoids plus the larger pressure-regulating solenoids.
Hot, thin fluid exposes worn solenoid seats and pressure regulator wear. Test the solenoid circuits first; if they pass, look at the valve body pressure regulator valve.
ZF LifeguardFluid 5, which ZF lists for its 5HP transmissions, or the fluid shown on your service label. Set the level hot at the fill plug and reset adaptations afterward.
