Default 2018 transmission fluid temp check

I am getting conflicting reports

for 2018 should temp be 104°F - 113°F or 115°F-126°F

I know I could also do the wire jumper and the D-N diagnostics.. but I want to double check temp with scan tool as well....

115-126 F is the correct range.
I pull my check plug as soon as it hits 115 to keep the fluid level at the high end of the allowable range.

Cycle through your gears as it warms up.
