I don’t understand the dipstick markings for the transmission fluid. The cold/add markings are at the end of the stick, implying a lower fluid level; while the hot markings are farther up the dipstick, implying a higher fluid level. But when the engine is cold, the fluid measures higher, and when it is hot, the level is lower — presumably because the fluid is still in the gears, etc. Are the cold/hot markings reversed?
Automatic transmission fluid levels are typically measured as follows...
1) ... on level ground, (of course!).
2) ... only when the fluid is hot.
3) ... only when the engine is running.
4) ... after all of the above, moving the transmission selector lever through all of the positions before settling on the park position.
The above procedure is how I do it, and is more thorough than what is described in the owner's manual on pages 333 and 334. If you do not have an owner's manual, there is one online at the Liberty CRD Facebook Page in the "files" section.
It appears from your description that one or more of the following may be occurring...
1) ... you are not seating the dipstick fully each time after wiping it off.
2) ... you are measuring the level on the dipstick when the engine is not running and the transmission is cold, while measuring the level on the dipstick when the engine is running and the transmission is hot. This will likely give you the readings you are describing. Fluids indeed have a greater volume when they are hot verses when they are cold, hence a higher level of fluid in the pan, (all other factors being the same), and the reason why you have the hot readings higher up on the dipstick than the cold readings. However, this is more than countered by the fact that there is less automatic transmission fluid in the pan where the readings take place when the torque converter is moving and the transmission pump is circulating ATF throughout the transmission.
