To find the correct fluid, you need to:
1. Find your Jeep's year: This is crucial.
2. Identify your transmission type: Look in your owner's manual or on a sticker located on the transmission itself (often near the dipstick). Common transmission types include various automatic transmissions (e.g., 3-speed, 4-speed, 5-speed, 6-speed, 8-speed, 9-speed) and manual transmissions (e.g., 5-speed, 6-speed). The manual will usually specify the transmission type.
3. Consult your owner's manual: The owner's manual will explicitly state the recommended transmission fluid type and specifications (e.g., ATF+4, ATF+6, Mopar ATF, specific synthetic fluid). This is the most reliable source.
Without the year and transmission type, any recommendation I give you could be incorrect and potentially damage your transmission. Always consult your owner's manual first.
