Additional Notes

  • The Jeep Wrangler TJ in 2.5 and 4.0 configurations for 1997-2002 share identical manual transmission fluid capacities, listed at either 3.3 liters or 2.28 liters depending on the specific transmission unit fitted to the vehicle.
  • The two capacity figures for 1997-2002 models, 3.3 liters and 2.28 liters, reflect different manual transmission assemblies used across the same engine variants rather than a fill level distinction within a single unit.
  • For 1997-2002 models carrying the 3.3-liter transmission capacity, the normal-use service interval is set at 37,500 miles or 30 months, whichever comes first, while the severe-use interval is halved to 18,000 miles with no time component specified.
  • The same interval structure applies to 1997-2002 models with the 2.28-liter capacity, where normal use calls for a change at 37,500 miles or 30 months and severe use reduces that to 18,000 miles.
  • Severe-use intervals for 1997-2002 Wrangler TJ manual transmissions carry no month-based limit alongside the 18,000-mile figure, unlike the normal-use intervals which pair mileage with a 30-month ceiling.
  • The 2002-2006 Wrangler 2.4 and 4.0 configurations each list two manual transmission fluid capacities, 2.3 liters and 1.98 liters, indicating two distinct transmission units were used across those model years.
  • No service change intervals appear in the specifications for 2002-2006 Wrangler manual transmissions, regardless of engine size or capacity figure, in contrast to the interval data present for 1997-2002 configurations.
  • The 3.3-liter capacity listed for certain 1997-2002 transmissions is notably higher than any figure recorded for 2002-2006 units, where the maximum listed capacity is 2.3 liters, pointing to a physically larger transmission assembly in the earlier period.
