The appropriate way to check it....Get your jeep up to running temp, put her in park, then run through each gear all the way down to 1 (or 2, cannot remember the lowest gear?), then back up to park. Leave the jeep running, get out and ck your fluid. Should be right on the HOT mark.

Sorry. Incorrect. The engine must be running. Otherwise, you will get an inaccurate reading. A properly serviced automatic transmission will read way over full if you read the dipstick with the engine off.

In the tranny service write up on the Project-JK site, it states:

22. Pull out your transmission dipstick and check it’s fluid level which should be about 1/8″ below the lowest mark on the dip stick. If necessary, add more fluid as needed and recheck the fluid level after your transmission has reached normal operating temperature, approximately 180°F.


what does it mean 1/8" below the lowest mark??? Where exacally do I want the level, there are 4 holes , 1 at add, 1 at cold, and 2 at hot.

When it says it should be 1/8" below the lowest mark, it is because at that point in the write-up, your fluid is cold. Plus, you want it at least on the stick before you run it too much.
It then tells you to recheck after the tranny warms up to normal operating temp. Then it should be near the "HOT" mark.
