4HP16 Transmission parts

Transmission general data

Number of gears Transmission Type Drive Torque (Nm) ATF (full capacity) L ATF (change) L ATF type (recommended)
4 AT FWD 240 6,9 4 LT 71141

The 4-speed automatic transmission ZF4HP16 for was released in the early 2000-th, when its predecessor ZF 4HP20 was thoroughly tested under operational conditions. The 4HP16 unit is a reduction design copy of the4HP20 solution. ZF 4HP16 is intended for lower torque (up to 240 Nm) and mainly produced by Korean companies under the ZF licence for FWD cars such as Daewoo, Chevrolet (Lacetti), Grand Vitara etc with the engine from 1.6 up to 2 liters. This transmission is the competitor of the U240 unit.

Technical issues and repair guidelines

The 4HP16 unit can be rarely found in repair shops. It it can be explained by the fact that this transmission, like all 4-speed ZF transmissions, is notable for its durablity and lack of major weaknesses. This transmission operates with different fluid types, but it is necessary to monitor the fluid level and its quality.


Repair and replacements

ATF change is accompanied by replacement of a one-time filter with a felt membrane. They are recommended for replacement after the second oil change, and for old cars – every time when changing the oil, that preserves solenoids and very expensive valve body.


Unilateral frictions usually get burnt in the clutch pack C. The responsive steel disc burns together with these friction elements. To solve this issue, ZF engineers changed the positioning of these three problematic friction discs in the following modifications. The piston is also frequently replaced during the transmission rebuilding. Spare parts in the 4HP16 unit are usually replaced in old torque converters. If this measure is neglected, then it may cause leaks in seals and the pump damage.


There are some minor problems with electrical components, which do not endure hot summer in the city and aggressive driving style with fluid overheating. Problems with contaminated solenoids lead to insufficient oil pressure resulting in problems with seals, bushings and pump with the torque converter. D and Е packages also get frequently damaged. Problems of old/worn-out transmissions (usually after 200 thousand kilometers) are similar to problems in the 4HP20 transmission.
