If one day you see that oil has been leaking from the gearbox on your XKR 4.0 it is likely that this is from the in-line electrical connector on the front right hand corner of the transmission. This will be due to ‘O’ ring failure. When doing this job I would also treat the gearbox to a filter and oil change if not done already. The image below shows the new replacement connector JLM21109 with O rings which were the cause of the leak on the old part.

Reasons for removing the cooling fans and the radiator:

1. Radiator replacement
2. Condensor replacement
3. Cooling fans replacement
4. Access to the front of the engine e.g changing the timing chains and tensioners
5. Good access to the lower cross member which is a bad area for corrosion

This method avoids the need to remove the pipework for the AC condensor. If the condensor is to be removed this would require the de-gassing and then the re-gassing of the AC system.

When we supply our good value service kits for this gearbox (filter, gasket and correct spec oil) I am often asked where the fluid fill location point is. It is not easy to locate when you are in a cramped confined area working underneath the car. As the diagram below shows this is as the right hand side rear of the gearbox
