Range Rover Evoque: Gear shifting malfunctions and unusual noises coming from the transmission

20 Nov 2020

Autodata Company runs Autodocta guide, where solutions to common, but difficult to diagnose, automotive problems are presented. This time the problem discussed is a gear shifting malfunction and unusual noise coming from the Evoque Range Rover transmission.

Our client complains about gear shifting problems and noise coming from the transmission in his 2015 Range Rover Evoque. During the vehicle inspection we noticed a low level of oil in the gearbox. We suspect that a major leakage is the cause. However, we were unable to find the cause of the oil loss under workshop conditions. Can you help us with this problem?

Answer: We have already dealt with the described problem, which concerns Range Rover Evoque models with transmission code 9HP48 manufactured after 2014. The leakage is caused by a defective design of the gearbox oil channel seal. Remove and dispose the gasket and mounting bolts of the gearbox oil channel plates. Thoroughly clean all clamping surfaces. Install a new version of the gearbox oil channel plate gasket, available in the Land Rover parts section. Re-install the oil channel plate using new mounting bolts and tighten them to the specified tightening torque of 10 Nm. Pay attention to the tightening sequence of the bolts securing the gearbox oil channel plates (fig. 1.1). If necessary, top up the oil in the gearbox. After the repair is completed, a test drive should be performed to see if the fault has been removed.
