    Gearbox issues

    Hi all got a little bit to post so please bear with me.
    The Disco went in to Landrover to have the rear flap repaired as it wouldn’t open and once it was in there they spotted an oil leak from under the engine protection.
    Obviously they couldn’t do anything then and it was booked in for this week.
    Before it went in I did notice the gearbox feel slightly notchy?
    Upon inspection they spotted that the leak was coming from the transmission tray, which they have apparently replaced the tray and seal and made sure it doesn’t leak anymore.
    BUT!!
    We got it back today and my wife phoned me saying it doesn’t feel right so could I drive it, upon driving if the gearbox is very jerky at very low speed between 1st and 2nd gear also when I give it some welly the change down was very noticeable which is not normal.
    So I phoned Landrover (dealer) and have it booked back in for Monday which was fine until I thought I’d pick my daughter up from school and on the way I tried to See where I could get the jolting at different speeds in different gears. Then a strong smell of burnt oil started which was very noticeable.
    Even my 14 year old noticed which is amazing as she notices nothing.
    I have now contacted Landrover assist as I obviously don’t want to damage anything by driving too far, which there will be a technician with me in the morning.
    Wish me luck.

    Must be something around this time of year, last night a vibration developed very quickly on a fast A road. Vibration became extreme before I could safely pull over when an almighty bang and "Gearbox Fault". I fortunately managed to coast into a lay-by with four on board. AA truck had no idea how to disengage the gearbox and the hazards drained the battery, second AA patrol came to get the battery a boost and do disengage the gearbox. Rear wheels seized solid (diff), and bizarrely they insisted on delivering it to my home rather than to a secure compound. Broke down at about 8:50, I was dropped home around 11:00 but then had to sign for the car when they delivered it (another two different recovery trucks) at about 2:30 am. B:3ack on another recovery truck at 9:30.

    Collected this morning at 9:30 and dropped to local dealer, and as yet no replacement car but enterprise en route with a Volvo XC60. Sales management in the dealership where completely indifferent, not even telling me in person they could not supply a replacement. Not impressed at all, I suspect this is something very major.

    Neill, if it's a V6d, from your description I would guess crank snapped, was common on D4 but D5 seems to suffer less. Transmission & driveline is pretty reliable. If car stopped, need to release transmission park pawl - release lever is under engine cover then release electric park brake, easiest way is to turn ignition off whilst holding handbrake off button down, that should release the epb.

    Oh blimey that sounds a bit more dramatic than mine, but we’ve just picked up a Lexus NX which seems very nice yet small. A bit of a faff by lr assist and enterprise but at least we have wheels for the week.
    Can’t wait for the phone calls tomorrow to start Rolling Eyes

    Thanks Trevor, I will ask the question tomorrow. The guy on the recovery truck like me thought the EPB release was similar to the D4, but after reading the manual (it now says separate instructions are available for recovery personnel, just not the ones LR assist send out). He called another AA patrol (also the battery was dead by then) and he released the Gearbox the way you described but the rear wheels were still not free, seized solid.

    Well I got mine back this evening and it turns out that the gearbox was not updated to let it know that there is new oil in it!
    It is running a lot better now it’s been updated but what a palaver just because they forgot to do the update.

    So it sounds like the smell of burning oil was trans fluid that likely had dripped onto the trans / diff housing, which once it got hot started to burn off and cause the smell?

    Not sure how the trans knows or cares it has old vs. new oil in it, and then behave as if it threw a knee out simply because it *thought* it had old oil....? Confused

    Well I know that when my old D3 had a gearbox flush the gearbox had to be reset on that, so there is definitely some truth in the fact that the gearbox adjusts over time to the viscosity of the oil. I also had them draught up a letter explaining what was done and what happened so I’ve got on record the details to show if needed later on.
    She’s driving like a dream this evening so fingers crossed it’s all good.

    they do need to be reset. My XC60, had to have the gearbox counter reset and the gearbox driven in a recalibration process whenever the ATF was changed, and I am assuming that old 6 speed box was far less sophisticated than the D5's 8 speeder...
