Service manual says:
1. Remove dipstick and insert clean funnel in transmission fill tube.
2. Add the following initial quantity of Mopar ATF +4 transmission fluid:
(a) If only fluid and filter were changed, add 3 PINTS (YES, PINTS NOT QUARTS) of ATF+4.
(b) If transmission was completely overhauled, or torque convertor was replaced or drained, add 12 pints.
3. Apply parking brakes.
4. Start and run engine at normal curb idle speed.
5. Apply service brakes, shift transmission through all gear ranges then back to NEUTRAL, set parking brake, leave engine running at curb idle speed.
6. Remove funnel, insert dipstick and check fluid level. If level is low, ADD FLUID TO BRING LEVEL TO MIN MARK ON DIPSTICK. Check to see if the oil level is equal on both sides of the dipstick. If one side is noticeably higher than the other, the dipstick has picked up some oil from the dipstick tube. Allow the oil to drain down the dipstick tube and recheck.
7. Drive vehicle until transmission fluid is at normal operating temperature.
8. With the engine running at curb idle speed, the gear selector in NEUTRAL, and the parking brake applied, check the transmission fluid level.
9. Add fluid to bring level up to MAX arrow mark.
