STATUS: My transmission is cooled by the OEM Cooler in the radiator + a small auxiliary cooler (~8" x 12") in series in front of the Radiator at the top passenger side.
BACKGROUND: I have a new temperature gauge in the transmission pan that appears to be working correctly, yet, I note that the temperature may be running higher than it should - upwards of 180 degrees on 70 to 80 degree ambient days, extended driving, relatively flat terrain, and towing a Geo Tracker. (Engine Temp will be running around 208) Also Note, the transmission was re-built 2 years ago with a new torque converter and seems to be shifting and running well. My Air Conditioning Cooler with Fan assist is located in front of the Radiator down low on the drivers side.
OPTIONS:
1) Keep everything as is, and become concerned when? or
2) By-Pass the Transmission in he Radiator (plug it off) and install a larger Auxiliary Transmission Cooler in front of the Radiator. (Eliminate the heat transfer between the higher engine radiator temperature and the transmission temperature in the radiator to lower cooling on the transmission)
a) Size of Auxiliary Transmission cooler to use? Dimensions, Fins etc?
b) Hayden http://www.haydenauto.com/Featured%20Products-Transmission%20and%20Engine%20Oil%20Coolers/Content.aspx
or other? With or Without Supplemental Electric Fan?
c) Best Location? Front Lower Passenger side in front of the Radiator?, At an angle in front of the Battery Tray beside the Radiator, Other?
d) Upgrade Transmission Lines, Best Diameter? Steel or high pressure rubber?
I have read numerous posts on this subject with a variety of successful results; however, I have not gleaned which one has been determined to be the most prevalent method to keep the transmission cool. What would that be?
