    I have a 2016 Chevrolet Silverado V8 5.3 pickup with the 8L90 transmission, What operating temperature should I be running? Just looking for feedback on standard operating temperature for daily driving with no load. Any feedback regarding transmission operating temperature is greatly appreciated. Would like to hear from some who run the 8L90 as well.

    Background: I got a transmission shop trying to tell me that 120* and under is normal operating temperature for a transmission with the bypass valve. Not buying it, so just gathering some information to back me up to provide when I pay them another visit. Fell free to provide your feedback on that claim as well.
