might be bad news if you hook up/have a trans cooler, yes/no?GTO fans will also work you just have to trim 3/4" off the bottom lip with air cut-off wheel & move the lines to the trans cooler slightly. Mine work real well with a 160 degree thermostat. It stays 1 to 2 marks left of center on the gauge. Mine where off a 06 GTO & same as new. ($200.00) e-bay.
