5HP24 Shift Kit 1996-2005, new and ready to install. Fits the 5HP24. Ships fast from the USA.
A V8 BMW 540i, X5 4.4, Audi A8, Jaguar XJ8 or Range Rover that bangs into gear on a kickdown, shifts harder every month, or has already cracked a drum is a classic case of runaway line pressure in the ZF 5HP24. This listing is called a shift kit, and it is sold under that name, but be clear on what arrives: the TransGo 5HP-24-PR pressure regulator repair kit, a new steel pressure regulator valve with sealing rings and a calibrated red spring. It does not recalibrate every shift circuit the way a full shift kit does. It fixes the one valve that most often causes these complaints.
The pressure regulator valve sits in the front lower valve body and sets main line pressure for the whole transmission. Every clutch, the converter and the lube circuit work from that pressure, and the electronic pressure regulators trim it from there. When the stock valve and its bore wear, the valve can no longer hold pressure down, so line pressure climbs. TransGo lists the results: runaway pressure that breaks drums, harsh shifts, and kick-down bang. The new valve carries scarf-cut rings that seal the worn bore, so you do not have to ream the casting or buy special tools.
If the car is already missing gears, the pressure regulator kit alone will not bring them back. TransGo says to install it as part of the overhaul in that case.
Rule out the electrical side first. TransGo's sheet lists the 5HP24 shift solenoids MV1 through MV3 at 30 to 35 ohms and the pressure regulators EDS1 through EDS5 at 6 to 8 ohms; our guide on testing a transmission solenoid with a multimeter covers the checks. Next, look at fluid level and condition with our drain and fill guide, since low fluid on these units causes its own harsh engagement. If the solenoids are in spec and the car shifts on time but hits too hard, the regulator valve is the likely cause. A slipping or neutral-at-a-stop complaint points elsewhere, often the upper valve body, which our 5HP24 valve body page explains.
The kit is for ZF 5HP24 and 5HP24A transmissions. The listing covers 1997-2003 BMW 540i, 1997-2001 740i and 740iL, 1996-1997 840Ci, 2000-2003 X5 4.4 and 4.6, 1997-2003 Audi A8, 2002-2003 S6, 2003-2004 RS6, 1998-2003 Jaguar XJ8, XJR and Vanden Plas, 1997-2002 XK8, and 2003-2005 Range Rover 4.4. TransGo warns that the kit only fits valve bodies with the pressure regulator vent in the location shown on page 1 of the instructions, so identify your valve body before you begin. Small parts under the separator plate are different on each model, which is another reason to send us your year and VIN if you are unsure.

No. It is TransGo's 5HP-24-PR pressure regulator repair kit: one pressure regulator valve, a regulator spring, sealing and sizing rings, and instructions. It corrects runaway line pressure rather than recalibrating each shift.
Yes, if the car still drives. TransGo shows how to drop the filter and remove only the front lower body of the valve body with the transmission in the car.
Usually not. That complaint is commonly an upper valve body leak in the F-clutch circuit. This kit targets harsh shifts, kickdown bang and drum breakage from high pressure.
It fits 5HP24 and 5HP24A units, but only valve bodies with the pressure regulator vent where TransGo shows it. Check your valve body against the instructions before you start.
ZF LifeguardFluid 5, the fluid ZF specifies for its 5HP transmissions. Fill and check level at the temperature ZF calls for.
