Section 2 (Diagnosis - 4-Speed): Description: Introduction

WARNING: This page is about a different car, the 1996 Suzuki Esteem. However, it is still accessible from the selected car via links, so may be relevant.

Automatic transaxle is electronically controlled. Transaxle shifting and torque converter lock-up are controlled by Transmission Control Module (TCM).

The TCM receives information from various input devices and uses this information to control shift solenoids No. 1 and 2 on transaxle valve body for transaxle shifting, and Torque Converter Clutch (TCC) solenoid for torque converter lock-up.

An O/D cut switch is mounted on gear selector lever. When O/D cut switch is depressed to ON position, transaxle will shift into overdrive (OD) when gear selector lever is in "D" position, and O/D OFF indicator on instrument cluster will turn off. When O/D cut switch is released to OFF position, transaxle will shift into 3rd gear, and O/D OFF indicator will illuminate.
