Introduction To A/T Diagnosis

WARNING: This page is about a different car, the 2014 Mitsubishi Outlander. However, it is still accessible from the selected car via links, so may be relevant.

When the A/T is failed, have an interview with the user to gather precise information on the failure status. After that, perform on-board test to check if the failure is reproduced, and then start repair work. If the repair work is started on the assumption that the A/T is the failure cause from the beginning, the cause would not be investigated, and moreover, the secondary failure may be caused, resulting in a waste of repair time.

Failures regarding the A/T are categorized as follows.

  1. Poor adjustment, poor installation between the engine and body, and malfunction due to non-genuine device installation
  2. Poor engine performance
  3. Malfunction of the electronic control device
  4. Malfunction of the A/T inside (hydraulic control system, etc.)
  5. Others (oil leakage, damage, etc.)
