VEHICLE: 2015 Range Rover Evoque
ISSUE: Poor gear shifting and abnormal noise from the transmission
DIAGNOSIS & SOLUTION:
A customer of ours has a 2015 Range Rover Evoque and they are complaining of poor gear shifting and an abnormal noise from the transmission. During inspection of the vehicle we noticed the transmission oil level is low which seems to be due to a large oil leak. So far we have been unable to find the source of the oil leak in the workshop. Can you help?
Yes, we are aware of the faults you describe which affect Range Rover Evoque models with transmission code 9HP48, 2014 onwards. The oil leak is due to poor manufacture of the transmission oil gallery plate gasket. Remove and discard the transmission oil gallery plate gasket and retaining bolts. Thoroughly clean all mating surfaces. Fit a modified transmission oil gallery plate gasket, available from Land Rover parts department. Refit transmission oil gallery plate using new retaining bolts and tighten retaining bolts to the correct torque of 10 Nm. Observe the correct transmission oil gallery plate retaining bolt tightening sequence (fig. 1.1.). Top up the transmission oil as required. Carry out road test to confirm the faults have been eliminated.
