A fellow GMC'er has asked:
RV starts out great; 2300rpm to maintain 65mph. But after a while it
may take 4000rpm to maintain 65mph. Then it rained a bit. Could a
little rain cool down the trans enough to get to function better?
That's what seemingly happened. I was back to 2300rpm & 65mph.
Ideas????

Larry, it looks as if Roger is asking for someone else.
One reason I say tach is because 2300 is too low to maintain 65 mph.

I am with Dan on this one. With my 3.07 gears the engine turns 2400-2500 to go 65. He must have been in 2nd gear for a while. If the torque converter was slipping that much rain would never cool it off.

Roger,
Your no longer flying these helicopters in
Vietnam. Your not to auto rotate.
I would keep an eye on that tach and also turn up the aux. ear plugs.

Tach failure is the problem. You guys hit it on the nose first try.
That's why we have you out there. <g>
