There's air flow... it's just on an air cooler a circuit away...

I haven't tried to do so myself good sir, but here is the sequence from the service manual. Perhaps you can compare and confirm it's exactly the same as you read elsewhere?Bruce,
Wonder if you could help me trying to check trans fluid level in my 21 pb. The Helm service info on CD mentions a diagnostic mode to keep the engine running while checking the level. It says to connect my diagnostic tool, then select the different shifter positions with engine running. Then place in park. Then push start button to enter accessory mode. Then press brake and accellerator together for 5 seconds , then within 15 seconds, release accellorator and brake and
press brake and start button. Then press brake and accellerator together for 5 seconds. It says "ready to drive" should be flashing while in diagnostic mode and engine runs continually.
I did not plug in the diagnostic tool, but did everything else. The engine did start when I pressed accellarator and brake together and software rev limiter stopped it just short of 4k. There was no
flashing indication of being in diagnostic mode.
Have you tried this? Do you know what I'm doing wrong? Sincere thanks for anyone that can shed light on this for me. Trans was warmed up when I tried this. I think it's all ok, just wanted to check for correct level.
True but somewhere there is an air to liquid cooler and if that's blocked or restricted. Also the liquid side could be restricted... either on the transmission side or the Low temp circuit side...The 10r80 has a liquid/liquid heat exchanger.
No air flow involved.
