Locate the gear fluid fill plug. It is a 17mm bolt located on the driver's side of the transmission, just below the shift linkage.
Clean the fill plug and the surrounding area to prevent contaminants from entering the transmission.
Remove the fill plug using a 17mm wrench.
Insert a funnel into the fill hole.
Add gear fluid slowly until it begins to overflow from the fill hole.
Replace the fill plug and tighten it securely.
Start the engine and allow it to run for a few minutes to circulate the new gear fluid.
Check the gear fluid level again and add more fluid if necessary.
Note: The recommended gear fluid for a manual 1995 Jeep Cherokee is SAE 75W-90. Be sure to use the correct type and amount of fluid for your specific vehicle.
