I replaced my 2002 Liberty with a 2014 Cherokee TH as I needed a good vehicle to tow my 3500# boat and to date the Cherokee has not disappointed - in fact I think it does a better job than the Liberty.
I however, have some questions on transmission operating temperatures. I have towed my boat from one end of Ontario to the other along highway 401 and general operating temperatures are in the 74/77 C (165/170 F) range with occasional spike to 80 C (176 F) when running up long or steep grades. These ranges seem normal to me. I recently got caught in a major traffic jam to due road construction with constant stop & go and the transmission quickly spiked to 90 C (194 F) causing me a lot of concern. I exited the traffic jam at the first opportunity, but not before transmission temperature reached 100 C (212 F). Once I got moving again it gradually returned to a normal operating temperature range.
Did I over react to the temperature spike to 100 C (212 F)? If so at what maximum temperature should I be concerned? Is there any operating procedure that can be done to help reduce climbing temperatures?
Any and all thoughts/advice will be much appreciated as I do not want to do anything to damage the tranny on this great vehicle.
