I got a 07 chevy 1500 about 3 weeks ago.It has the driver information center on the dash and it tells the trans temp.Ive been watching it and the highest it gets is 170 after fully warmed up and going through all the gears at full throttle. This morning on my 20 mile commute it peaked at 136 and that was right when I was pulling in my driveway.Should I put a peice of board over the factory cooler until the warm months come back around.I know Ive read somewhere that 180 was ideal trans temp.Am I just worrying over nothing.
