Over-heating on long grade

[David Brady]

I'd add that you were probably running it for significant
periods of time out of torque converter lock-up. The transmission
runs on torque converter mode till you hit the upper rpm
range of second gear at which point the torque converter
locks and you have direct mechanical drive. In non-lock,
the torque converter provides fluid drive which causes
a bunch of heat. Try to go fast enough to put her in lock-up.
Lock-up feels like another gear shift. Count the shifts, strive
for three at a minimum. This will significantly cut down on
the transmission heat, and will also cut down on engine
heat. The tranny does a good job of baking the engine.

Yes. YOu have a cooling problem. Check to see that the radiator is not covered with junk on the outside. If that is clean, then have your radiator checked and flushed. If that doesn't get it, replace the thermostats. WARNING: It doesn't take much overheating to cost you an engine.
