What is the gear I should be in to climb the Grapevine grade?
You really should learn to check the fluids yourself; oil, water and transmission at a minimum. Doing so might save you a TON of money down the road.
He was trying to tell you that cleaning out the radiator might help.
You should be in whatever gear gets your engine speed back to where it normally is for highway cruising, probably around 2000 to 2500 RPM or a bit more. It is possible, and likely even, that the transmission might downshift for you and no manual intervention will be necessary.
But then.....if that is already happening....the transmission is downshifting AND the speed is falling AND the RPMs are going up AND it is still getting hot (above 220) having the cooling system serviced probably is a good idea, for piece of mind if nothing else.
