Transmission overheating is commonly caused by low or contaminated transmission fluid, cooling system problems, worn internal components, heavy towing, or excessive heat. A complete inspection can identify the underlying cause and help prevent further damage.

7. Your Check Engine Light Turns On

Many drivers assume the check engine light only relates to engine problems. However, the transmission is monitored by your vehicle’s onboard computer, and many transmission issues will trigger a dashboard warning.

If you’re searching for information about check engine light transmission problems, it is important not to ignore the warning. The light may indicate:

  • Shift solenoid problems
  • Transmission sensor failures
  • Internal slipping
  • Hydraulic pressure issues
  • Electronic control system faults

A professional diagnostic scan reads stored fault codes and helps technicians identify the source of the problem accurately.

Prompt diagnosis often helps prevent additional transmission damage.

How Professionals Diagnose Transmission Problems

Professional diagnosis involves much more than reading a dashboard warning light. At 616 Auto Repair, our technicians follow a complete inspection process to identify the exact cause of transmission concerns.

Our diagnostic process typically includes:
