I'm pretty sure the temp gauge is correct. I have a switch to go between engine temp and trans temp. I have a 180 thermostat, and when the engine is warmed up, the gauge sits right on 180. BTW, that was a pretty huge cooler sitting right in front of the radiator.

Then the sending unit is suspect. The only reason I'm firm on that is I run the below cooler on a fullsize Silverado that makes 540rwhp (Dynojet number) and weighs 5200lbs. I runs 175* on a hot summer day driving around town.

Dimensions on the Tru-cool is 22.75" x 8.5" x 1.25"

The cooler you have isn't that big and its a tube and fin which doesn't dissipate heat nearly as well as a plate and fin. I just want to make sure that there isn't something being overlooked and giving you a false reading.
