Dorman Automatic Transmission Oil Cooler Thermostat

The Dorman Automatic Transmission Oil Cooler Thermostat (also called a transmission cooler thermostat or transmission fluid thermostat) helps keep automatic transmission fluid in its proper operating temperature range. It is a replacement for a worn or failed OE thermostat.

Key Features:

• Regulates the flow of transmission fluid to the oil cooler based on fluid temperature
• Helps the transmission warm up faster in cold conditions, which supports smoother shifting and reduces wear
• Helps prevent overheating by sending fluid through the cooler once it reaches operating temperature
• Designed to replace the original equipment part for a dependable fit and function
• Backed by Dorman's quality standards and engineering for aftermarket replacement parts

A transmission oil cooler thermostat that works properly helps protect internal transmission components, supports consistent shift quality and extends transmission life.
