I have outlined both procedures below.

TRANSMISSION FLUID CHECK

1. Verify that the vehicle is parked on a level surface.
2. Remove the dipstick tube cap.

WARNING: Risk of accident from vehicle starting off by itself when engine running. Risk of injury from contusions and burns if you insert your hands into the engine when it is started or when it is running. Secure vehicle to prevent it from moving off by itself. Wear properly fastened and close-fitting work clothes. Do not touch hot or rotating parts.

3. Actuate the service brake. Start engine and let it run at idle speed in selector lever position "P".
4. Shift through the transmission modes several times with the vehicle stationary and the engine idling
5. Warm up the transmission, wait at least 2 minutes and check the oil level with the engine running. Push the Transmission Oil Dipstick into transmission fill tube until the dipstick tip contacts the oil pan and pull out again, read off oil level, repeat if necessary.

NOTE: The dipstick will protrude from the fill tube when installed.

6. Check transmission oil temperature using the appropriate scan tool.

NOTE: The true transmission oil temperature can only be read by a scan tool in REVERSE or any forward gear position.

7. With the transmission in "P", determine the height of the oil level on the dipstick and using the height, the transmission temperature, and the Transmission Fluid Graph, determine if the transmission oil level is correct.
8. Add or remove oil as necessary and recheck the oil level.
9. Once the oil level is correct, install the dipstick tube cap.

TRANSMISSION FILL

1. Verify that the vehicle is parked on a level surface.
2. Remove the dipstick tube cap.
3. Add following initial quantity of Mopar(R) ATF +4, Automatic Transmission Fluid, to the transmission:
a. If only fluid and filter were changed, add 5.0 L (10.6pts.) Of transmission fluid to transmission.
B. If the transmission was completely overhauled or the torque converter was replaced or drained, add 7.7 L (16.3 pts.) Of transmission fluid to transmission.
4. Check the transmission fluid (see above)
