| Transmission Coolers |
|---|
The key to automatic transmission life is keeping the transmission fluid fresh, clean and cool. When fluid temperature exceeds the optimum operating range of 160 to 200 degrees, it begins to burn, decreasing the life of the fluid and in turn the life of the seals, bearings and all moving parts. Installation of a cooler will extend the life of the transmission and help prevent costly repairs. |

| Choosing the Right Transmission Cooler | |  | | Select the correct transmission cooler by determining where there is enough space to mount it. The diagram on the left numbers the best three positions to mount the transmission cooler in order. Transmission coolers are more efficient when they receive maximum air flow. At Position 1, the transmission cooler is 100% efficient. Position 2, between the air conditioning condenser and radiator, is 75% efficient while Position 3, between the radiator and fan, is only 60% efficient. If positions 2 or 3 are used, a larger transmission cooler will be needed to compensate for the loss of cooling power. If this is the case, choose a transmission cooler that is one or two sizes larger. Tech Tips: Transmission fluid can not be over cooled, but it is critical in extreme cold conditions to allow the vehicle to warm up before driving. |
