Question for the 5.7 w/6 speed auto and auto temp gauge.
After shutting the truck down, and coming back 3 hours later, the temp gauge still read in the middle. Anyone else's truck doing this? I would think it should have cooled off some.
thanks

Mine does the same thing. I relate it to not having other parts on it (like the engine does) that can absorb the heat. Kind of like metal insulation if you would....

engine and transmission may cool off on the outside but the fluid may still remain at operating temp for a long time

All the transmission's internal parts are still warm so they are keeping the fluid warm.

thanks everyone, glad to hear it is not just my truck.
i understand the tranny will hold heat, but you would think it would cool down some, and not stay at operating temp 3 hours later. guess not........

There is a big hunk of steel inside the trans that has to cool off, that takes a while since there isn't any fluid circulating.
