I've been searching all over for "what is the normal operating range temperature for the Aisin tranny under a decent load (i.e. 18k trailer)?
This is a new truck to me and my other truck is a 2016 and it runs significantly cooler under the same load with same everything that I can tell. Aisin, HO diff, same trailer, 30 degrees cooler?
I've tried to wash the cooling fins out for possible compacted dirt, etc all drive train fluids changed, filters, nothing makes any sense to me.
Newby, thanks you pros in advance for your thoughts.
