Technical issues and repair guidelines
The main maintenance requirement for this transmission during many years of reliable service is timely ATF change (Dexron III or Dexron VI) and fiilter replacement every 100 thousand kilometers. The torque converter unit of this transmission easily operates for 200 thousand kilometers without any repair. There is no much information related to the repair of hard parts of the ZF 4HP14 unit to draw some patterns, because this transmission operates properly for a long time and the car gets too old before the first transmission overhaul.
The most popular parts ordered for the overhaul of this transmission are the following:
- Repair kit of gaskets and seals (Overhaul Kit),
- brake band
- pump bushing (or turbine shaft bushing) and friction clutches
In most cases, repair specialists have to repair frictions in the Forward pack and steel discs. The kit of steel discs is ordered not so often for repair, because friction components wear out rather than get burnt.Seal, pump, and turbine shaft bushing are the first to get burnt because of vibrations and overheating of the worn-out torque converter.
In all other respects, this transmission is quite simple and almost problem-free. After the valve body cleaning, the torque converter reassembly, and proper repair this gear shifting unit becomes extremely robust.
