Additional Notes

  • The automatic transmission fluid capacity across all listed Jeep Wrangler TJ configurations — the 2.5 (1997-2002), the 4.0 (1997-2002 and 2002-2006), and the 2.4 (2002-2006) — is uniformly 3.8 liters, indicating a service fill rather than a full overhaul capacity.
  • For the 2.5 and 4.0 engine variants covering 1997-2002, normal use conditions carry a change interval of 37,500 miles or 30 months, whichever comes first, combining both a distance and a time-based threshold.
  • Under severe use conditions, the 2.5 and 4.0 variants from 1997-2002 require an automatic transmission fluid change every 12,000 miles, which is roughly one-third of the normal use interval of 37,500 miles.
  • The 30-month time limit paired with the 37,500-mile distance interval for 1997-2002 normal use means a time-based service trigger applies independently of mileage accumulation, relevant for vehicles driven infrequently.
  • For the 2002-2006 model years, both the 2.4 and the 4.0 engine variants share a severe use change interval of 60,000 miles, a figure five times greater than the 12,000-mile severe interval specified for the 1997-2002 configurations.
  • The shift from a 12,000-mile severe interval in 1997-2002 to a 60,000-mile severe interval in 2002-2006 represents a substantial difference in service frequency between the two generation spans, despite the fluid capacity remaining identical at 3.8 liters.
  • No normal use interval is listed for the 2002-2006 2.4 or 4.0 configurations; only severe use data appears for those model year ranges in the specifications.
