    Dr Tranny for Auto Shudder fix

    Hi all,
    Thought I would share this with you all, my mechanic has had a customer who has had shudder in his auto transmission for 2 yrs!

    He regularly tows and it has been getting progressivley worse for him.
    I mentioned to my mechanic the use of Dr Tranny to fix the problem.
    He ordered some in: Dr. Tranny Instant Shudder Fixx
    2 tubes recommended
    As well as some of this: LUBEGARD Automatic Transmission Fluid Protectant
    1 bottle recommended
    The owner was facing a large bill so they decided no harm trying this fix.
    Well it's been 2 weeks for him, the result:
    Instant Fix!
    Shudder completely gone.
    He has even towed again without any signs of shudder, he is over the moon to say the least!

    This brings me to my D3!
    I have regularly changed my fluids but was feeling that I was possibly developing a slight shudder. ( I am very proactive in looking after my D3 mechanically)
    I got my mechanic to put in the Dr Tranny x2 and Lifeguard protectant which on the Disco3.uk forum had recommended the use of 2 of these as well. Well all was good until I had to head away for work to Batemans Bay. On the freeway on cruise control doing 110kph going up hills it did not drop down to 5th, it would labour and then the dreaded "F" Transmission fault limited gears available - 3rd only.
    I stopped and restarted probably 5 times to reset the fault. I eventually plugged in my Faultmate and found a couple of codes:
    P0730 & P0735 which comes up as "Incorrect gear ratios" for both of them.
    I cleared them and drove on, trying semi auto mode to see if I could manually override the issue. Nope, it just confirmed the gear selection problem.
    Back home in Sydney and speaking to my mechanic and doing some homework we decided to drain and change the fluid again as well as adaptive gearbox reset and clutch calibration to see if that would fix it.

    And - Yes it did, all clear after testing up and back on the F3 to Gosford.

    Ok what caused it - we think that the addition of the 2 bottles of Lifeguard Protectant 600ml was probably too much as they had no issues with the other D3 adding just 300ml.
    I'm now relieved that I do not need a new transmission!

    Dr Tranny is still fantastic stuff if you have shudder.

    Good to know in case I do develop shudder down the track, but for now it's probably best to follow the old farmers proverb: "If it ain't broken....."

    I asked Bruce Davis whether to put Dr Tranny in my gearbox when converting the sumprecently and he advised against it. As I have no shudder I took his advice however if it's a question of new gearbox or trying it I definitely give it a go.

    I would have to agree Steve, only add if you have a definite shudder diagnosed.

    After I had experienced a shudder under load while towing , my Gearbox was double flushed at 96 000km as well as 108 000 km with the expensive Shell 1375.4 OEM oil, the shudder never went away.
    I was told by the agent and ZF i require a new torque converter, and there are nothing they can do further.

    Well at 108 000km I walked away from my agent,googled the problem and did according to what I have found out as a last resort.
    I then drained the oil, flushed it 3 x times with Fuch ATF 4400 added 2 x tubes of Dr Tranny , and voila!. Smooth as new.

    I have now done as of today 40 000 km with Dr Tranny and the Fuchs oil.

    I tow an off road trailer here in Africa , and uses the vehicle to launch a boat on the beach regularly.

    For the last 40 000km have not experienced any shudder and the Fuchs oil has kept my gearbox smooth as it was new.

    Dr Tranny worked for me as well as Fuchs ATF , if it lasted for 40 000km with no issues it will last another 100 000km at least , this mileage is over 60% of towing and touring.

    I resolved my annoying shudder at a fraction of the cost quoted by agents.


    Ps, apparently the shudder is caused by a glaze forming on the clutches inside the torque converter from extreme working conditions, Dr Tranny has got ethers that removes this glaze.

    Dr Tranny also works in the Transfer case , if you have a knock turning right going uphill , it's from the transfer box add 1 x tube of Dr Tranny and it's gone.

    Plenty of D3's in Africa has been fixed by adding 2 x tubes in gearboxes and 1 x tube in transfer box.
