Comprehensive Component Monitor - Automatic Transmission

General

The MIL is illuminated for all emissions related electrical component malfunctions. For malfunctions
attributable to a mechanical component (such as a clutch, gear, band, valve, etc.), some transmissions are
capable of not commanding the mechanically faile d component and providing the remaining maximum
functionality (functionality is reassessed on each power up). In such case a non-MIL Diagnostic Trouble
Code (DTC) will be stored and, if so equipped, a Transmission Control Indicator Light (TCIL) will flash.
For example on the CD4E transmission, if a gear ratio is not properly obtained and verified due to a
mechanical malfunction, the unobtainable gear is no longer commanded for that power up, the DTC is
stored and the TCIL flashes.

6HP26 Automatic Transmission


This transmission is operated by a stand-alone transmission control module (TCM). The MIL related
Diagnostic Trouble Codes will be transmitted via CAN to the Engine Control Module (ECM), and the
MIL illuminated, for all emissions related electrical and mechanical component malfunctions. For
malfunctions attributable to a mechanical component, this transmission may be capable of not
commanding the mechanically failed component a nd providing the remaining maximum functionality
(functionality may be reassessed on each power up). The TCM may be interrogated for transmission
information attributable to setting either code. The TCM Diagnostic Trouble Codes are addressed via a
separate document enclosed.







Auto Shift Manual (ASM) Transmission

The ASM system is based around a standard manual transmission with a clutch and mechanical selection
of a set range of gear ratios (in this case 6 speeds). In this application both clutch and gear selection
operations are controlled via a Transmission Contro l Module (TCM) which commands hydraulic actuators
based on commands from a number of inputs.

The driver actions of depressing and releasing the clutch pedal to control clutch actuation and the shifting
of gears using a gear lever have, in essence, been re placed by a TCM, hydraulic actuators and electronic
switches.

With ASM the demand to shift gears can either be direct from the driver (as in a conventional manual
transmission), or controlled automatically by the system based on parameters such as road speed, current
gear selected and throttle demand.

The MIL is illuminated for all emissions related electrical component malfunctions. For malfunctions
attributable to a mechanical component (such as a cl utch, gear, actuator, etc.), functionality is reassessed
on each power up. In such case a non-MIL or MIL Diagnos tic Trouble Code (DTC) will be stored and, if
so equipped, a Transmission Control Indicator Light will activate and/or a message will be displayed. For
example on the ASM transmission, if a gear selection is not properly obtained and verified due to a
mechanical malfunction, then the amber Transmission Control Indicator Light will activate and the
message center will display 'GEARBOX FAULT'. In addition, the powertrain MIL will activate and a
DTC will be stored. The TCM Diagnostic Trouble Cod es are addressed via a separate document enclosed.
