Transmission Failures
Dur to Overheating
and Neglect


Routine servicing is the single most important aspect of extending the life of your transmission and preventing transmission failures. Overheating causes 90% of all transmission failures according to the industry feedback and most of them can be blamed on worn-out transmission fluid that should have been replaced. Automatic transmissions generate a lot of heat through friction, and it doesn't take long for the (ATF) to heat up once the vehicle is in motion. The normal temperature range of which most transmission fluids are designed to operate is about 195 degrees fahrenheit. Elevated transmission temperatures cut the life of the transmission fluid. To be safe service your transmission once a year or every 20,000 miles and always refer to the vehicle's owners manual for service and warranty instructions.

Most new cars have a system that monitors the performance of your car. If something is not working properly, the "Check Engine" light usually comes on. The good news is that this "pre-warning" system can help you avoid costly damage, which may be occurring with your vehicle, by detecting small problems before they become big problems. However, the only way to be certain is to have your car inspected by an expert mechanic when the "Check Engine" light comes on.

The approximate life expectancy at various temperatures is as follows:

Transmission Failures Are Usually Caused By:

Transmission Repair

Transmission Failure
Due to Overheating
and Neglect

  • Neglect and lack of routine maintenance
  • Low Transmission Fluid Levels
  • Intermittent voltage drop
  • Faulty Sensors and Solenoid
  • Normal Wear = Mechanical components do wear out and eventually cause the transmission to fail.
  • Abuse, overheating, overloading, racing, and other activities beyond the design critera of the transmission.

Transmission Failures Due To Elevated Temperatures


195 Degrees fahrenheit Normal operating temperture
220 Degrees fahrenheit Danger
240 Degrees fahrenheit Danger
260 Degrees fahrenheit Failure at 15,000 miles
295 Degrees fahrenheit Failure at 4,000 miles
315 Degrees fahrenheit Failure at 2,000 miles
