    2010 D4 3.0L Transmission Issue 111,000kms

    Hi all,

    For the last year or so I've found that my transmission seems to hover at around 1900RPM in each gear before continuing to accelerate.
    I had the oil changed in the ZF box recently by Fluidrive at about 105k km's, later than I would have liked for its first box oil change, who did the steel pan conversion and assured me they used the proper Lifeguard oil. I doubt they flushed it- I think most oil changes get about 5 of the 14 L out at a time?
    I reset with my IID tool, and the problem improved by say 50% for a while but never really went away, and seems now to be back to square one. Coming up through the gears, especially in Drive (its slightly better in sports mode), it 'hovers' at times before continuing to rev.
    I checked the transmission oil the other day using the allen plug up on the side of the box - it came out quite clear - not sure if I'm relieved or not - at least if it was skungy or had bits of metal in it I'd have context to the problem and be able to talk to fluid-drive about it.
    I called a Land Rover Indi who's about 1 1/4 hrs away who said it could be a torque converter- not sure I know much about this?
    I fancy I read something on another forum about a similar problem but can't find it at the minute - I think he improved it by flashing the CPU.. or perhaps use of an additive that can help.
    Would any kind AULRO gents be able to throw any advice?
    I am located in Bendigo and would welcome any suggestions, advice, links, or recommendations as to who should look at it.
    Cheers and thanks,
    Jon.

    If the Indi you are referring to is in Romsey, then I would heed their advice. But for a definitive assessment, I would take the car to A&B Automatic Transmissions in Dandenong who are authorised ZF repairers. That's where Landrover send their transmissions.

    Cheers, yes, I trust the guys at Romsey.
    Called AB - thanks for the lead - and they were helpful though I admit I’m nervous. He said he needs to test it, but it sounds like a torque converter and he’s saying a new transmission is possibly needed. $5-6k. Fair to say I’m a bit stressed about it now!

    At 110,000km with "experts" saying it is a torque converter - why would it need a new gearbox?

    Says the torque converter degradation can cause slurry and damage the other gears, causing problems in the future..

    5 to 6 k is about right for a 6hp26 overhaul. At 111k i would 100% hope that the lifeguard 6 was used during the previous services.
    If there are no trans fault warnings on the dash and no limp mode warnings yet then you really need to get the pan off and check the magnets and filter for particles. There is a bushing wear issue with those model years that is accelerated by using a non OEM oil..

    It is folly to use anything BUT LF6...

    The Range Rover L322 4.4.TTDV8 ....probably won't bother with the remap..😈
