    Default ZF & Dr Tranny

    So it's been a fairly mundane weekend. So armed with the attached fluids, a clean oil squirt can and some time.
    I removed the top oil cooler feeder hose next to the radiator.
    With my previous disco 3 I squirted the additives into the radiator but this time around RR Sport - and since the red Viennas has shrunk ( I don't recall these being so tiny) I could put all in the oil squirter with ATF protectant

    I took about 53 squirts and I was 80% done.
    The rest of the additive mix was put into a big syringe and I could empty that 100ml into the feeder pipe.

    All clamped back and now for the road test.

    NB 6000km ago I did new sump and life guard oil.
    This additive and shudder fix are merely preventative measures.

    1x Lubegard Platinum ATF Protectant

    Well done.

    I was thinking the other day, our Merc w169 A180 auto has a bit of a shudder every now and then- wonder if Dr. Tranny would do the trick on the cvt gearbox??

    Ok, after about 65km,
    I'm VERY happy to report that the ZF Tranny has become even smoother, outside temp is about 33 deg C and the box behaving exceptionally well.
    Up shifts are a lot better, with time taken to upshift, downshifting has particularly become "unnoticed"

    Remember with the fresh oil and new sump / filter things were already smoother . . .
    This additive -- WHAT EVER IT DOES OR WHATEVER IT IS SUPPOSE TO DO -- has just made this ZF box better.

    Will keep this updated and will sit in CPT N2 traffic this afternoon and will definitely get a feel from the clutches and their 'new found' life . .

    If it's a chain drive (like the Audi) I would be very careful as the CVT oil has the property to harden under pressure to enable chain on metal drive and only if Dr T will support that will it work.

    Few quick questions:

    1. How did you manage to get everything in the transmission via the pipe. i tried it, but pipe filled up so quickly, could hardly get 1 tube of tranny fix in there...Was it done under pressure ?
    2. Did you have the transmission adaptive values reset after the oil flush. I've been told it must be done after an oils change, transmission repair or Torque converter change.

    Ja, I also struggled to get 1x tube in the pipe. Anyone adding Dr.Tranny should take out plenty of oil first! But yes, Dr. Tranny eats up those shudders and smooths out the gearbox.

    Ok chaps some context.

    my Rangie was parked overnight and stood for two full days.
    I squirted all in one operation both (little) tubes AND platinum additive into the top hose which on the V8 is apparently the return feeder pipe. didn't have to wait for fluid to settle into the pipe. Honestly didn't have ANY issue feeding all thru this way, even that last bit with the syringe, maybe had to do with the Rangie being parked for two days that the return pipe was empty . . . . .

    Re Adaptation; this was all done when ZF did the flush and new sump in early Dec last year

    cheers

    Dr Tranny is amazing stuff. I had my ATF flushed, filter replaced and 2 x Dr Tranny added to my D3 at around 140 000km. The shudder returned recently (now at 180 000km) and I booked it in at another indie for flushing but without Dr Tranny. I was time pressed as the flush was booked for Wednesday and I was due to drive to Namibia on the Saturday and the shudder and TC slip had become quite harsh, so I was concerned, would this work or would I need to go to Nam in the far less comfortable bakkie?

    The day after the flush, the shudder was about 90% better but there was still quite a bit of TC slipping so I took it back to the indie and asked him to add 2 tubes of Dr Tranny - by this time I was getting worried that we wouldn't be able to make the trip in the disco and that I was in for a hefty bill for work on the transmission.

    Within kms of adding the Dr Tranny all was back to normal. We've just returned from a ~2600km trip to Namibia (500km on dirt roads) without incident. I am definitely going to buy some more of this stuff and also possibly the ATF protectant.

    To fill from bottom is quite easy.
    Remove the guard
    Drive the vehicle on a ramp, , bricks or grass bank let it lean far over to one side, hell now I cant remember which side is the filler.
    Open up the level plug and squirt in, , works the quickest.

    Default ZF & Dr Tranny

    Hey all I've done now about 10 000km give or take a few hundred Kms and have just praise for the ZF.
    The thing is after the oil change, there was no distinction between a cold and warm transmission, with the additives it's become even smoother.
    She behaves the same, early morning, during the day and those late nights when the foot is slightly heavier
    I would recommend the Dr Tranny AND the oil change (DONE PROPERLY) to ANYbody with a ZF box that has mileage on it.
    #NOT_Actually_filled4life

    My previous D3 diesel got the same TLC and the results were the same and I sold around 195000km without issues!!

    Go and do it in conjunction with fresh oil
    Just a word of caution this was more preventative for me. The oil change and the Dr Tranny will not 'rectify' any mechanical issues already experienced.
    Cheers
    JC

    Where do I buy Dr Tranny please!

    I am having the gearbox oil changed soon in my D3 and it seems to be right thing to add.

    Thanks,

    Stupid question, but would this still be effective if i do the oil change and service at ZF and then have my indy add the DR Tranny with the next visit a week or 2 later?

    Or do they have to both go in 1 shot?
