Hi everyone,

I have noticed on my 2009 that the tranny temp gauge seems inconsistant. Sometimes the gauge shows that the tranny heats up quickly and sometimes it doesn't seem to heat up very fast at all. It almost seems that the gauge is not reading some days. I have only had the truck for one week and am still monitoring it. It has been a fairly consistant temp outside so I have ruled out the outside temp change. Some of the time the tranny seems to heat up very fast and other times is seems to take its time. Is this possibly a sensor issue or a gauge issue. I am currently monitoring it and would like some input before the dealer sees it for warranty.

Thank You,

 

it's also possible that the thermal cooler bypass valve is sticking open sometimes, not allowing it to heat up. i would take it in and make sure it's not making metal or friction material.

 

the 09s now have a tranny temp gauge?

 

Yup! Sure do!..........

 

Thank you for the response! I thought that it might have such a device. I will check into this further.

Thank You,
