Issue:
A customer may report an oil leak under the vehicle from the
transmission suspected to be the sump pan. Engineering would
like to investigate the root cause as to these concerns
To ensure correct diagnosis and repair please carry out the
following steps:
Action
1. Raise vehicle on ramp
2. Using a suitable degreaser, thoroughly degrease the
suspected component all the way around as well as,
approximately, 25-50mm (1-2 inches) above the suspected
leak
3. Using an air gun ensure all traces of oil are removed from the
bolts/thread attached to the sump pan.
4. Using a suitable leak detector spray, thoroughly coat the
suspected component as well as, approximately, 25-50mm (12 inches) above the suspected leak, LR112798 or C2C42090
5. Allow to sit for a couple minutes to ensure all oil has been
cleaned off
6. Take a clear, in focus photo of the spray on the suspected
area before proceeding.
7. Reassemble vehicle and complete a suitable road test and
make sure that the engine gets to normal operating
temperature
8. Return the vehicle to workshop and raise on ramp
9. Inspect the suspected component for fluid leaks, the detector
spray should leave a trace from the leak area
10. Identify leaking position:

following areas:
Check Technical Bulletins reference Automatic
Transmission leaks
Transmission output shaft seal
Transmission oil cooler pipes not secured correctly

torques for the sump pan bolts (as detailed in attachment) and
raise an EPQR attaching photos of leak and breakaway torque
attachment.
