Additional Notes
- The Jeep Wrangler JL (EU) 2.0, 2.2 CRD, and 3.6 variants all share an automatic transmission fluid capacity of 9 liters under normal use conditions, indicating a consistent transmission platform across those engine configurations.
- The 2.0 4xe PHEV carries a slightly lower automatic transmission fluid capacity of 8.5 liters under normal use conditions, which reflects the modified transmission architecture associated with the hybrid powertrain integration.
- A 9-liter automatic transmission fluid capacity is a relatively high service fill volume, which is characteristic of modern multi-speed automatic transmissions with larger fluid reservoirs designed to maintain thermal stability over extended operation.
- The 0.5-liter difference between the 2.0 4xe PHEV at 8.5 liters and the non-hybrid variants at 9 liters represents a meaningful divergence in service fill requirements, meaning the two cannot be treated as interchangeable when performing a fluid service.
- All four configurations list normal as the use condition tied to the stated capacities, meaning the 9-liter and 8.5-liter figures apply specifically to standard operating environments rather than severe-duty cycles.
- The 2.2 CRD and 3.6 share the same 9-liter capacity despite being a diesel and a petrol engine respectively, indicating the automatic transmission unit itself, rather than the engine type, determines the fluid volume requirement in the Wrangler JL (EU) lineup.
