Automatic Gearbox, JATCO - Fluid Level Check VERIFY PROPER PLUG IS REMOVED FOR LEVEL CHECK CAUTION: Because of the similarity to other plugs and fasteners on the transmission, the potential for loosening an incorrect fastener, instead of the level plug, exists. There is a risk for internal transmission damage if the improper fastener is removed. Removal of the reduction gear brake band bolt can cause total loss of drive or a substantial reduction in the performance of the transmission Removal of the parking pawl rod plate retaining bolt (located next to the XYZ switch) will result in problems / gear lever movement restrictions. Under NO CIRCUMSTANCES must these items be removed or loosened. Doing so will invalidate any warranty claim made. Damage caused by improper service procedures is NOT warrantable. Check and top-up fluid WARNING: Avoid excessive skin contact with mineral oil. Mineral oils remove the natural fats from the skin, leading to dryness, irritation and dermatitis. Position vehicle on ramp. Apply handbrake and position chocks under front and rear wheels. Remove underbelly panel, following this sub-repair --> Remove
