Chery Tiggo. Manual - part 238
Operation
Automatic transaxle control is divided into the electronic and hydraulic transaxle control functions. While the elec-
tronic transaxle control is responsible for gear selection and for matching the pressures to the torque to be trans-
mitted, the transaxle’s power supply control occurs via hydraulic elements in the electro-hydraulic control module. The
fluid supply to the hydraulic elements, such as the torque converter, the shift elements and the hydraulic transaxle
control, is provided by way of a fluid pump connected to the torque converter.
The Transaxle Control Module (TCM) allows for the precise adaptation of pressures to the corresponding operating
conditions and to the engine output during the gearshift phase, resulting in a noticeable improvement in shift quality.
The engine speed limit can be reached in the individual gears at full throttle and kickdown. The shift range can be
changed in the forward gears while driving, but the TCM employs a downshift safeguard to prevent engine over
speed. The system offers the additional advantage of flexible adaptation to different vehicle and engine variants.
