How To Replace Your Manual Transmission Fluid – Jeep Wrangler JK (2007-2018)

How Often Should I Replace My Transfer Case Fluid?
Jeep recommends changing the manual transmission fluid every 30,000 miles in your Jeep Wrangler JK. If you’re not doing any towing, plowing or driving in hot weather conditions for long periods of time, you can get away with a longer change interval. To be on the safe side, I always change the transmission oil every 30,000 miles.
What Is Needed
Replacing the manual transmission fluid in your JK is an easy task and only takes some basic hand tools. The tools and materials you will need are:
NSG370 Manual Transmission Lubricant (2 qts.)
Drain Pan
14mm Hex Socket
17mm Hex Socket (Modified)
Ratchet
Torque Wrench
Crescent Wrench
