Transmission Time..

[uncleal13]

Hi Matt, AL here truck 159.
Two trucks ago I had an air cooled transmission. It was fine on the prairies, but pulling the mountains it got way too hot. I saw well over 300 degrees many times climbing the Coq and Kickinghorse. It needed vehicle speed to get sufficient cooling, which you can't get going 25 kph up a mountain.
Although mine had the cooler mounted above the tranny, if it was up front it would be better, or a fan that could be turned on.
