Automatic Transmission (AJ16)
8.1.1 GENERAL DESCRIPTION
’ This section provides information relating to the automatic transmissionsfitted to the 3,2 liter engine (ZF 4 HP 22 trans- mission) and the 4,O liter normally aspirated engine (ZF 4 HP 24 E transmission). The general arrangement of the two
units is shown in Fig. 1 and Fig. 2. The two automatic transmission units differ in the type of control unit employed:
the purely hydraulic control used in the ZF 4 HP 22 unit shifts gears automatically at predetermined points, while the
electronic-hydrauliccontrol oftheZF 4 HP 24 E unit providesforoptimized shift point sand shift quality based on engine
and transmission data received by the Transmission Control Module (TCM).
