Thread: Dr Tranny for Auto Shudder fix

This Dr Tranny "shudder fix" reminds me of the old "NO SMOKE" I use to put in my 1972 Ford Escort, stop the smoking but reduced the power.(not that it had much to start with)
Not judging, but I wonder if it can cause any lack of performance? Thoughts?

Note that my D4's box does not shudder and never has. 5th gear now often fails to engage on down-shift after which it either returns to 6th if under light load or free-wheels then goes to limp mode. 5th also now disengages under only moderate load and jumps to 6th so I've taken to manually dropping straight to 4th on hills. I hope it will last until it gets removed in 8 days time.

after reading this forum I had the same symptoms on my D4.. shuddering at around 1600rpm when I put some load on it or was going up hills. I took it to Landrover in Melbourne and of course they said I needed a new transmission (around the 10K quote!!!) BTW my D4 has done 150K (2010 model) and all the time I had it serviced at Landrover they never advised the oil should be changed etc.. Until I read this forum I realised that this is not the case about the "Lifetime no change/sealed Tranny)

I have a great mechanic in Geelong who has done work for me and has been really good at not ripping you off and fair on the costs etc..so I phoned him with this issue and explained about the Dr Tranny and he said he would give it all a go rather than fork out the $10K.. He replaced the pan with the new metal.. flushed it twice and added 2 tubes.. I drove it home today and it drives just like to new.. I know it is early days but as of today I am very pleased with the outcome..

Will keep you posted as to how it goes..

I have a 2008 Disco 3 206K kms.. slight shudder.. I'm in Bendigo Vic
What is a "Faultmate"? Can I get one? Does it come with a manual of code meanings?
Where can I get Dr Tranny and is Lubeguard really necessary..

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.

Faultmate is a diagnostic computer made by Blackbox Solutions. They also make the Nanocom diagnostic system.

Tbh, I think that BBS have almost buried themselves with poor customer service. I think that the almost universal choice is the IID tool in BT or non-BT configurations. Wonderful design and superb customer service.

Interesting take. I, for one, have had nothing but great service from BBS. I admit that BT would be great, though.

I had a BBS Nanocom, which I have sold to a member here, and found the service was very good too. Since bought a GAP IID Tool for the ease of use via bluetooth to drop the car to it's bump stops to help my wife in and out of the car. A couple of clicks and it's done - magic. Service and response here too was very good. There's no doubt that the Nanocom is an excellent tool and so is the IID Tool but the blue tooth compatibility makes the IID so much easier to use IMOH. From memory I bought the Nanocom because the price was a lot lower and it had an excellent reputation. When buying the Gap IID Tool I found that the price difference is a lot closer now making it a much more viable option than before.
