Additional Notes

  • The Jeep Grand Cherokee WJ with the 4.0-liter engine was paired with two different automatic transmissions, the 42RE and the 44RE, which carry noticeably different fluid capacities of 9.1-9.5 liters and 7.57 liters respectively.
  • The 9.1-9.5 liter capacity range listed for the 42RE reflects a typical total fill figure that accounts for fluid held in the torque converter and transmission pan combined, which is why a range rather than a single value appears in the specifications.
  • Under normal use conditions, the 4.0-liter Grand Cherokee WJ carries an automatic transmission fluid change interval of 102,000 miles or 102 months, whichever comes first.
  • Under severe use conditions, the same 4.0-liter Grand Cherokee WJ requires an automatic transmission fluid change at 30,000 miles, which is roughly one-third of the normal-use mileage interval.
  • The severe-use interval of 30,000 miles applies equally to both the standard 4.0 and the 4.0 AWD configurations across the 1999-2004 model years, with no difference in the change interval between the two drivetrain variants.
  • The 4.7 V8 Grand Cherokee WJ, covering the 1999-2001 model years, carries a substantially larger automatic transmission fluid capacity of 13.3 liters compared to either transmission option available in the 4.0-liter configuration.
  • The 13.3-liter capacity of the 4.7 V8 transmission is consistent with a larger unit designed to handle the torque output of an eight-cylinder engine, and the higher total volume reflects a more substantial hydraulic circuit within the transmission assembly.
  • Both the 4.7 V8 and the 4.7 V8 AWD configurations share the identical 13.3-liter capacity and 30,000-mile severe-use change interval, indicating no fluid volume difference between the rear-wheel-drive and all-wheel-drive versions of that engine pairing.
