Print

The manual transmission oil should be replaced at 37,500 miles (60,000 km) intervals.

FLUID RECOMMENDATIONS



The use of 10W-30 weight engine oil meeting API service specification SH is recommended for use in all manual transmissions.

ATF+3II or equivalent automatic transmission fluid can be used as a substitute for the transmission's engine oil if high shift effort is experienced during warm-up in cold weather.

  1. Park the vehicle on a level surface, turn the engine OFF , firmly apply the parking brake and block the drive wheels.

Ground clearance may make access to the transmission filler plug impossible without raising and supporting the vehicle. If the vehicle must be raised, it must be supported at four corners and level. If only the front or rear is supported, an improper fluid level will be indicated.

  1. Remove the filler plug from the side of the transmission. The fluid level should be even with the bottom of the filler hole.
  2.  
  3. If additional fluid is necessary, add it through the filler hole using a siphon pump or squeeze bottle.
  4.  
  5. Carefully install the filler plug and tighten to 27 ft. lbs. (37 Nm).
