What is normal transmission temps?

Recommended Posts

I haven't driven my truck more than an hour at a clip but I'm hovering around 200°F seems high to me. My other trucks with a 4l80e do not run near that hot without towing.

2021 Chevy 2500HD 6.6 Gas here at 1k miles now - my Bank iDash is showing 184-188F trans temp (once warmed up) unladen, whether on interstate or in town in 45-65F ambient temps.

Thermostats. They start to open around 192 F (89 C) plus or minus a bit and full open about 10 degrees higher. Your 4L80 didn't have a thermostat.
