Just pulled the cover off the my automatic transmission to fix a leaky seal. I bought a used Wrangler and there is no owners manual.

So, how much ATF+4 goes in this thing? Thanks!

This is the whole procedure, including quantities:

Fron the FSM:

1. Remove dipstick and insert clean funnel in transmission fill tube.

2. Add following initial quantity of MoparŽ ATF +4 to transmission:
a. If only fluid and filter were changed, add 3 pints (1-1/2 quarts) of ATF +4 to transmission.
b. If transmission was completely overhauled, torque converter was replaced or drained, and cooler was flushed, add 12 pints (6 quarts) of ATF +4 to transmission.

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, and 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 noticably 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 re-check.

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.
CAUTION: Do not overfill transmission, fluid foaming and shifting problems can result.


9. Add fluid to bring level up to MAX arrow mark.

When fluid level is correct, shut engine off, release park brake, remove funnel, and install dipstick in fill tube.

you can download an owner's manual online. since you have an auto you may want to install an auxiliary transmission cooler and temp gauge. these beasties run too hot. if you have an 08, there is currently a recall for the automatics. search for J30 recall for more info.

Great advice! You really will see a noticable difference in the temp after adding the cooler...the factory solution is no solution (recall) at all so go with the cooler!
