On my girls 1990 K2500 with the 5.7 and 700R4 transmission, we are going to get a smaller 2 axle trailer for weekends, either a conversion or from a manufacturer. The radiator is like new and I did just run all steel transmission cooler lines. With the trailer weight of approximately 5k to 6k loaded, I plan to give the transmission every chance I can. It is not the original transmission. It was replaced by a GM dealer in state of Washington, in 2012 at approximately 110k miles. It is close to 123k miles now.
When I took over work on this truck about 20 months ago, I did a transmission filter and fluid change. I did not do a flush and it all looked pristine in there. I now want to install an external transmission cooler and am reaching out to members here to get ideas of a good made cooler, fit and function, and if there is anything special I need to know. It all looks very straight forward but there is a reason I am a member and I will use info from you all.
