I've got a 2006 silverado with a 4L80E.
Yesterday while on the freeway the transmission temperature rose to 250*.
I got off the freeway, checked the fluid, etc the fluid level was good and didn't seem to smell burnt. I let it cool down for about 20 minutes and turned the key on and it was still hot. I felt the cooler and it wasn't hot. After the transmission temperature got back below 200*, I started driving again (not on the freeway). It got back up to 250* after a few miles.
This morning, it took about 1/2 hour, maybe longer of city diving to get above 200*.
Could there be something causing the fluid to not circulate through the cooler?
While I was sitting waiting for it to cool down, I called my mechanic. His guess was clutches.
It shifts smoothly and doesn't slip.
I'm hoping some transmission guru has an answer.
I haven't checked for codes, or actually checked the pan temperature when it was hot.
