ZF 5HP30

Transmission general data

The 5-speed automatic transmission ZF5HP30 is one of the first 5-speed transmissions with a maximum torque. This transmission was developed for special vehicles with RWD and powerful engines with the capacity from 4.5 liters.

In terms of design, this transmission is related to 5HP24 (intended for a bit lower torque) and has some common spare parts (such as seals and solenoids) with a legendary 5HP19. Compared to 2 abovementioned transmissions, ZF5HP30 has the reserve of structural integrity. This transmission was designed to become an "invincible" unit without obvious soft spots and a high safety degree in all components.

Technical issues and repair guidelines

The transmission requires a planned overhaul after running well beyond 300 thousand kilometers (under the condition of normal operation and timely fluid change). The transmission reassembly is performed together with filter replacement, torque converter repair and replacement of rubber and paper gaskets. The drum (Forw/Rev. Clutch A+C) is considered to be a soft spot of this transmission (aluminum teeth get cu

All solenoids are replaced with the purpose of ensuring reliability, because their resource usually comes to an end after 7-10 years of exploitation together with wear-out of the torque converter. The worn-out torque converter clutch is the main source of premature ageing of solenoids and as a consequence – problems with pressure in packages. In general, this transmission is quite reliable with a high safety reserve on transmission elements.
