I have not been able to positively identify the level in my trans since changing the fluid a few months back. It seems to run and shift okay, but I would feel a lot better if I knew the fluid level was correct.

I have searched the forum, and the most absolute method I have read about is the one where you remove the modulator valve and add fluid until it just begins to come out.

I've textured the dipstick also without much, if any, success in being able to tell for sure where the level is.

My question is this: The modulator valve method states to run the engine to get the fluid circulating in the converter and lines. I may be just stupid here, but no one has stated (that I have found) if you leave the engine running when you pull the modulator valve or have it shut down. Which is the correct method?

After further searching, I found the answer. Rob M. states to turn the engine off before removing the modulator valve. I should have kept looking...

I may have read it here but if you pull the dipstick to check the level, use a clean paper towel behind the business end when reading. If you hold them both still and together the fluid should stain the paper towel at the actual level.... making it a BIT easier to transpose to the calibration marked on the dipstick.

That dipstick method also works on oil dipsticks.
