I thought that transmission fluid drained back into the pan from the cooling lines and torque converter after the engine stops and everything cools down, which would make the level in the pan, measured on the dipstick with the engine at rest, higher. So if you start the engine and measure as described, that would immediately lower the reading mark as fluid is pumped out of the pan and into the converter and lines. Does the fluid level then get higher as the transmission warms up, and if so, why? (I'm not disputing what you say, I just don't fully understand).
And I've always been frustrated trying to read a transmission dipstick while the engine is running, fluid splashing all over in there from, presumably,engine vibration and fluid movement from the transmission pump. Why don't 'they' provide a marker that clearly identifies the correct level when the engine/transmission are cold and 'at rest'?
