5r55e fluid level when cold...help please

This may seem like a silly question, but for those of you that have a proper fill of fluid in your automatic 5r55e can you tell me where the fluid level is on the dipstick when the engine is off and cold? I am having trouble getting a good read on the level when the engine is running and the fluid is warm...seems to be in different spots all over the bottom of the dipstick. When the truck is off and cold the level is about 1/4-3/8" above the full level of the hashmarks. I dumped the pan and replaced the filter yesterday and ended up adding about 4 qts, the best I could estimate what came out. I appreciate the help and until I drive it anymore I want to make sure it is not overfilled.

I think I may have found the answer to my own question...this is a TSB from 1998 but I would think the 5r55E Ranger/Explorer trans hasn't changed much since then.

Drew a little fluid out and got it right on the halfway mark between the bottom of the hashmarks (low level) and the first hole towards the bottom of the dipstick from there. The truck has been in the garage all day and last night, not driven, and its about 52 degrees in there so I should be right where I should be as far as the fluid level.

I used this guys idea for extracting some of the fluid. Worked well and I can use it in the future for exchanging a quart or two of fluid during an oil change. The bleeder tool was about $29 at Autozone, the new tubing and barbs was about $5 at Lowes, and I used a Mason jar and lid we already had. Good idea!
