Additional Notes

  • The Jeep CJ-7 / CJ-8 (USA) for 1985-1987 carries a manual transmission fluid capacity of 3.3 liters, a figure shared with several other configurations in the same lineup.
  • Wrangler 2.5 (USA) models from 1987-1993 also specify 3.3 liters for the manual transmission, placing the capacity on equal footing with the earlier CJ-series specification.
  • A capacity reduction appears in the 1994-1997 Wrangler 2.5 (USA), where the manual transmission fluid fill drops to 3.2 liters, a modest but distinct change from the preceding 1987-1993 figure.
  • The Wrangler 4.0 (USA) for 1994-1997 shares the same 3.2-liter manual transmission capacity as the 2.5-liter variant of the same years, meaning the two engine configurations converge on an identical service fill despite differing displacement.
  • The Wrangler 4.2 (USA) covering 1987-1993 specifies 3.3 liters for the manual transmission, aligning with the 2.5-liter Wrangler of the same period rather than diverging based on engine size.
  • All five configurations list a normal use condition, meaning none of the capacity or service specifications are tied to a severe-duty or first-change-only scenario.
  • The 3.3-liter figure appears across three separate configurations spanning 1985-1993, covering both the CJ-series and early Wrangler generations regardless of engine displacement.
  • The shift from 3.3 liters to 3.2 liters between the 1987-1993 and 1994-1997 Wrangler 2.5 (USA) represents a 0.1-liter decrease, which in a manual transmission context can reflect a revised gearbox design or updated fill procedure for the later model years.
