In 1995, the German concern ZF introduced a new 5-speed automatic transmission with the index 5HP24, which was intended for rear/all-wheel drive BMW models with a powerful M62 V8 engine. This gearbox was also installed on some Jaguar and Range Rover models also with V8 engines. There was a reinforced version of this automatic transmission for all-wheel drive Audi and Volkswagen sedans, which was installed with both a 4.2-liter V8 engine and a 6.0-liter W12 engine.

By design, this is a conventional hydraulic automatic transmission based on a Simpson planetary gearbox. It stands out for its valve body with eight solenoids, which was very sophisticated for its time.

Gear ratios ZF 5HP24

Using the example of a BMW 540i 2000 with a 4.4 liter engine:

Main 2.810
1st 3.571
2nd 2.200
3rd 1.505
4th 1.000
5th 0.804
Reverse 4.096

The transmission was installed on:

  • Audi A6 C5 (4B) in 1999 – 2004;
  • Audi A8 D2 (4D) in 1996 – 2002;
  • BMW 5-Series E39 in 1996 – 2003;
  • BMW 7-Series E38 in 1996 – 2001;
  • BMW 8-Series E31 in 1996 – 1997;
  • BMW X5-Series E53 in 2000 – 2003;
  • BMW Z8-Series E52 in 2002 – 2003;
  • Jaguar XJ 6 (X308) in 1997 – 2003;
  • Jaguar XK 1 (X100) in 1996 – 2002;
  • Land Rover Range Rover 3 (L322) in 2002 – 2005;
  • Volkswagen Phaeton 1 (3D) in 2001 – 2011.

Disadvantages of the ZF 5HP24 gearbox

  • The valve body spool valves are equipped with short-lived return springs; over time, the tension in them weakens and the gearbox begins to push during shifts. Wear of the Teflon coating of valves and cracks of hydraulic accumulators are also common.
  • The most notorious weak point in this transmission is the input shaft drum, which does not tolerate overly aggressive driving and the circlip breaks out of it. Many service stations offer to replace the regular drum with a reinforced version.
  • At mileages of more than 200,000 km, the rear hub bearing often wears out, then play in the hub appears, which wears out its teeth in engagement with the drum, tears rubber seals, and so on. Therefore, it is important not to skip the beginning of the process.
  • Since this gearbox is installed only with powerful engines, frequent and sudden starts here quite significantly reduce the life of the torque converter lock-up clutch. Also in this gearbox, various bushings, an overrunning clutch and a heat exchanger are often changed.
