TJM transmission underbody guard keeps the vital components of your Nissan Navara protected with a TJM Transmission Guard. A simple collision with a tree stump or rock could cause significant damage to the steering, engine sump or transmission, leaving you stranded and out of pocket. Our underbody guards are shot blasted, e-coated and finished in a black powder coat for corrosion resistance and durability. For maximum protection combine a front underbody guard, sump guard and transmission guard.
