FLUID RECOMMENDATIONS



Recommended lubricant for AX4/5/15 and BA10/5 manual transmissions is SAE 75W-90, API Grade GL-3 gear lubricant. Warner T4 & T5 manual transmissions use DEXRON®II automatic transmission fluid.

LEVEL CHECK



See Figures 1 and 2

The level of lubricant in the transmission should be maintained at the filler hole on all manual transmissions. This hole may be located on either side of the transmission case.

  1. Raise and safely support the vehicle using jackstands.
  2.  
  3. Remove the filler hole plug.
  4.  
  5. Being careful of sharp edges, insert your finger into the filler hole. The lube should be within 1 / 4 in. (6mm) of the bottom edge of the hole.
  6.  
  7. After checking the level, make sure to reinstall the filler hole plug. Tighten the filler hole plug to 27-33 ft. lbs (37-44 Nm).
  8.  
  9. Lower the vehicle.
