Cooling Requirements Oil-To-Water
Transmission Cooling System With Remote Bypass
For certain applications, the recommended transmission cooler routing is to bypass the engine thermostat system. With
this type of cooler routing, transmission oil temperature is more directly related to engine temperature. Listed below are
conditions which may require the use of a thermostat bypass:
1.
Under certain conditions, such as extreme cold temperature operation or extended periods of low speed oper-
ation, the engine alone may not generate the amount of heat required to open the thermostat. Without a ther-
mal bypass system, no cooling is provided for the transmission under these conditions.
2.
The thermal bypass system will provide faster warming of the transmission oil during cold weather warm-up
by circulating the warmer engine block coolant through the transmission cooler.
