    Has anyone else had this issue ?

    Good morning,

    Could you provide more info please?

    Where is the leak originating from? Have you de-greased the area and attempted to check after a good drive?

    I would suggest start there, most likely its only the sump gasket, but that also does not make sense as these gearboxes are "lifetime" and would not be opened by the dealer unless leaking.
    I suspect that someone that is not the dealer attempted an oil change (gearbox) on the Jeep and either reused the old gasket or did not tighten the bolts correctly. (Ysters lieg nie )

    I would do this myself if I were you...

    Trips down the V of the engine and comes out at the top of the gearbox so can be hard to diagnose.
    The transmission cooler is integrated into the condenser, you will clearly see the oil stain on the face of the condenser with a flashlight.

Is there a ZF specialist in Randburg?
    Hows your oil levels in the box?

    Low transmission oil levels are known for delayed gear changes and other gremlins.

    Or it could also be software related.
