Description & Operation: Introduction

The M5DA is an electronically controlled 4-speed automatic transaxle. Transaxle contains hydraulically operated clutches, which are controlled by the Powertrain Control Module (PCM). PCM receives information from various inputs and uses this information to control solenoid assembly for proper transaxle operation.

The first step in diagnosing any driveability problem is verifying the customer's complaint with a test drive under the conditions the problem reportedly occurred. Before entering self-diagnostics, perform a careful and complete visual inspection. Most transaxle control problems result from mechanical breakdowns or poor electrical connections.
