Ron I also replace the radiator core in 04/02 it
made a big difference.

If the alarmstat doesn't solve or help the problem, I'll be definitely
looking at checking the radiator. Pretty majoy job however.

I would be more inclined to replace the core than rod it. I don't
want to take a chance that the transmission cooling core could leak
into the engine coolant. Just as soon have it all new.
