    Discovery 3 Transmission Fault and recommended Perth repairers

    Hi guys,
    Just returned from an epic road trip from Perth to Tamala Station, Steep Point, Dehnam and Monkey Mia.
    Tonnes of driving blacktop and unsealed heavily corrugated roads.
    No major issues apart from a totally destroyed tyre.
    This is my first major trip whilst having owned the car for around 25,000k of fault free driving.
    The car had a full service record at purchase.
    The only thing I have done maintenance wise was a full service (did not touch the gearbox) and installed a new primary battery.
    The gearbox always had a very slight shudder around the 90k/hr zone.
    The gearbox always had a bit of play where if you were going around a round-about and you unsympathically sunk the accelerator heavily with the right foot would clunk and engage. You could/can avoid the clunk by feeding in the accelerator pedal.
    The weather was pretty good apart from the last day with a fair bit of heavy water across the road.

    When driving back into the first intersection in Geraldton, stopped at the lights and went to accelerate away and there was no drive. More accelerator pedal and the D3 started to pull away with lots of slip.
    Got to the next intersection, put the transmission into N and then Park.
    With the car running, the gear selector would not come out of Park with or without my foot on the brake pedal.
    I quickly turned the car off and on and I could select drive and drove away without any slip.
    Got to the local park - kids stretched their legs for a bit.
    Got back in the car and then the car started to play up.
    Lots of chiming from the dash, warning lights popping up and dissappearing. Battery check light coming on and off. F fault and error message on the dash. Gear shifting a bit clunking.

    Filled up the car. Drive restored and no warning lights on the dash or fault messages.

    Limped back to Perth on a couple of occasions stopping to turn the car off and on again to restore drive and reset the Fault message (limited gears available). Since getting back to Perth the spurious fault reappears. What I am getting now is static noise through the speakers (never had this before in 25,000k of ownership) kind of like popping. The car makes a weird noise and then the Fault message (limited gears available) appears. When I get to an intersection, the drive is kind of like a heavily worn clutch in a manual car. You have to press the accelerator quite a bit to get the car moving (lots of tooting from impatient people behind), find a place to stop, turn the car off and on and then the fault seems to reset.

    I don't have an OBD port reader thing to check the error message. I don't take my car to a regular mechanic as I do the maintenance myself.

    As a starting point, I was planning to take the car back to the dealership where I bought the car as they have access to a Bosch diagnostics system and get them to check the error codes. From there make a decision of how to proceed. Changing the oil, pan and filter may not be enough. I was also thinking to remove the underbody protection and check all the plugs and give then a squirt with WD40 etc to ensure a good connection.

    Prior to the trip I was planning to change the gearbox oil and plastic pan to a metal one complete with separate filter. At the same time I would replace the connector seal (black and orange released with the white clip). I don't know the transmission oil age or condition.

    I am based in South Perth and work around Kwinana / Rockingham area, does anybody have any recommendations of gearbox repairers or mechanics that they would recommend to take the vehicle to? Everyone will have their own experience and comments. I can't justify a full rebuild but would need to have a reliable vehicle. I was thinking torque converter, oil, filter, connector seal.

    What could the problem be that the fault can be reset by turning the vehicle off and on? Could something have wiggled loose with the hundreds of kilometres of driving on corrugated roads combined with water ingress?

    Cheers

    How many kms on the car ? A oil and filter change would be my first start point . If it still has a plastic sump then i am guessing its never been changed , but i have heard of people re-fitting a plastic sump so i could be wrong.

    Also check your selector cable isnt clogged up or come loose or something silly like that.

    I dont know perth well enough so cant recommend anyone.

    Transmissions R Us at Balcatta. Maybe not close to you as you would like but I have used them a couple of times and friends I know with D4s have used them also. Ask to speak to a guy named Cameron about your woes, he is very familiar with Landrover (ZF) stuff.

    But I suspect like it or not you might be up for a full rebuild.

    Thanks Ferret. I read a separate post regarding ZF oils etc and Transmissions R Us came up then as well. Cheers

    The battery light coming on and off tends to draw me to checking the charging system first. At 265k yes the trans is on borrowed time, however none of the Transmission failures I have come across have ever had a battery light in the equation. Do yourself a huge favour and get a decent scan tool if doing your own work!!!

    Exactly what I was thinking. The electrical issues mentioned in the first place might imply alternator issues Discovery 3 Transmission Fault and recommended Perth repairers
