The friction behavior has been optimally adapted for these transmissions, and is consistent over the entire service life. These features are a prerequisite for perfect shifting characteristics and vibration-free operation.
Application
ZF LifeguardFluid 9 was specially developed for use in ZF 8HP and 9HP automatic
transmissions:
8HP65APH, 8HP65AXPH, 8P65FLPH, 8P70H, 8P70XH, 8P75PH, 8P75XPH, 9HP48QXR, 9HP48QXO, 9HP48QX, 9HP48Q, 9HP48QL, 9HP50, 9HP50Q, 9HP50QX
Please note that only ZF LifeguardFluid 9 may be used for these transmissions (where
applicable, also available from the relevant original equipment manufacturer as a genuine spare
part). Using other transmission fluids can lead to various adverse effects, ranging from
significant deterioration in shifting characteristics to transmission failure.
Changing the transmission fluid is generally only necessary when repairs are carried out; ZF automatic transmissions are usually filled with lifetime oil. However, due to the many
factors influencing the service life of transmissions in individual operation, ZF recommends an
oil change after 150,000 km (approx 93,000 miles) for its transmissions.
In operating conditions with high temperatures and loads, or with unknown vehicle use in the
past, it can make sense to change the transmission oil at shorter intervals.
Important
- When changing the fluid, only the approved transmission fluid may be used for the fluid change
- Must be shaken vigorously for at least 15 seconds before dispensing the fluid from the bottle.
