On the 2014 Jeep Wrangler, there isn’t a traditional transmission dipstick for the automatic gearbox. The level is checked through a side-fill/check plug on the transmission housing, accessible from the engine bay on the passenger side. This is a sealed transmission design common to many Wranglers of that era.
Automatic transmission (2014 Wrangler JK)
For Wranglers equipped with the automatic transmission, follow these steps to locate and check the fluid level using the side-fill plug.
- With the vehicle on level ground, start the engine and bring the transmission to normal operating temperature by driving gently for a few minutes, then leave the engine running in Park with the parking brake set.
- Locate the side-fill/check plug on the passenger side of the transmission case. It is typically a small hex-headed plug about mid-height on the case.
- Carefully remove the plug using the appropriate wrench (commonly an 8 mm hex). Have a shallow drain pan ready for any fluid that may escape.
- If transmission fluid begins to seep out of the hole, the level is correct. If nothing comes out, add Dexron VI automatic transmission fluid slowly through the same opening until it seeps out, then reinstall the plug.
- Reinstall the plug and wipe away any spilled fluid. Check for leaks and ensure the plug is tightened to the proper torque spec.
Access can vary due to exhaust routing and underbody clearance, so some owners need to raise the vehicle or consult a shop if the plug is difficult to reach.
Manual transmission (if your 2014 Wrangler has a manual)
Some 2014 Wranglers offered a 6-speed manual transmission. These units also use a fill plug on the side of the transmission case rather than a dipstick. Check level with the vehicle on level ground and refer to the owner’s manual for the exact fluid type and fill procedure.
- With the vehicle on level ground and the engine off, locate the side fill plug on the manual transmission (usually on the passenger side, near the top of the casing).
- Remove the plug and add the recommended gear oil until it begins to seep from the hole, then reinstall the plug.
- Ensure there are no leaks around the plug after reinstalling.
Because manual transmissions can vary by build and model year, always confirm with the service manual or a qualified technician for your specific Wrangler configuration.
Summary
In short, a 2014 Jeep Wrangler does not use a traditional transmission dipstick for the automatic transmission. The level is checked via a side-fill/check plug on the transmission housing, accessible from the engine bay on the passenger side. If your Wrangler has a manual transmission, it also uses a side-fill plug rather than a dipstick, with the level checked in a similar fashion. When in doubt, consult the owner’s manual or a certified mechanic to ensure correct procedure and fluid specification.
