Description
Description and Operation
Transmission Assembly
This electronically controlled five speed unit is unique to supercharged vehicles.
Introduction

Parts List
Transmission Fluid
It is not necessary to change the transmis sion fluid in normal service; routine level checking is not required. The sealed
dipstick tube is fitted for service requir ements only, with a dipstick being availa ble as a special tool and NOT fitted as
standard.
Components and Functions
Transmission Casing
The following components are housed within the casing;
ItemPart NumberDescription
1—Torque converter housing
2—Breather
3—Transmission casing
4—Drive flange (output shaft)
5—Fluid pan
6—Selector lever

Engine torque reduction request MIL status (whether present DTC should operate MIL) Transmission input speed Transmission output speed Converter slip Kickdown status Gear position (actual) Gear position (selected) Gear selection fault Converter lock-up status Current selected shift map Transmission oil temperature Transmission malfunction Pecus flag (state of current TCM program) Target for next gear position Gear shift torque transfer progress at shift MIL status (response to activate the MIL relevant to a DTC) OBDII fault code clear acknowledgement Transmission DTCs (P codes) Token for network status TCM Diagnostic data out to external device (PDU)
Emergency Running (elect ronic limp-home mode)
The TCM constantly monitors the transmissi on for faults. In the event of a problem the TCM will adopt the limp-home mode, in which the gear currently held remains engaged, until P is selected. The modulati ng and shift pressures will increase to
maximum and converter lock-up will be inhibited.
Following the selection of P , the only ratios available will be 2 (irrespective of forward ratio manual selection) and R .
With the vehicle at rest, the procedure to manually select is as follows:
1. 1. Select P .
