Hyundai Venue: Automatic Transaxle Control System / Transaxle Control Module (TCM). Description and operation

Hyundai Venue (QX) (2020-2024) Service Manual / Automatic Transaxle System / Automatic Transaxle Control System / Transaxle Control Module (TCM). Description and operation

Description

•	Monitors the vehicle's operating conditions to determine the optimal gear setting.

•	Performs a gear change if the current gear setting differs from the identified optimal gear setting.

•	Determines the need for damper clutch (D/C) activation and engages the clutch accordingly.

•	Calculates the optimal line pressure level by constantly monitoring the torque level and adjusts the pressure accordingly.

•	Diagnoses the automatic transaxle for faults and failures.
