Dr Tranny for Auto Shudder fix

gents...im up exactly the same river here.


Had "lifetime seal" cracked and new pan etc put in with apparent "flush". Got a single system error a few weeks after that but had the shudder. Mechanic whacked in 2 x Dr Tranny and since then I've had same fault reads as ~Rich~ whenever I go for a hard gear change either way. Limited gears available and on the scanner incorrect gear ratio 5th gear etc.
Mechanic has washed his hands off me and didn't return calls etc and I relocated to NSW around same time (chit trip that was).
I've been driving around for 4 months now and as long as I babysit the gear changes (under 2.5k rpm) she goes ok and doesn't trip the fault code. As soon as I put some stress on the gear changes it definitely trips and I just pull over when possible under the "limited gears available" in 3rd and turn on/off and away we go.
Every man and his dog want to replace the tranny.. even over the phone they are making snap calls without even a thought. I read this post and it sounds like this could be my fix as well considering it isn't playing up outside of the fault code??
Rich.. I will even drive up to Sydney from newy to see your mechanic if no one can recommend anyone in or around Newcastle to fix this up for me?

Chilli,
Yes that sound exactly like my problem way back at the beginning of this thread.
I had my box drained as mentioned and recalibrated and it's lasted another 50,000 k.
So that would be my first action.

But alas the time has come for me to bite the bullet and get it replaced.
This time it will be serviced every 50,000k

Cheers Mate... I might drain and give Fuchs a go. Feels like im pushing you know what up a hill though. How problematic was that 50k you got out of her??

Not a problem for at least 40,000k then the shudder and occasional torque converter clutch solenoid stuck open or failed fault code.

P.S mate.. are you really going to drive 10+ hrs to go to Cohuna Auto??

No my local LR specialist will do the work.

Ah so old mate in Cohuna will do the reco and ship to your local mechanic? Is that right mate. sorry for being a pain but I will probably end up doing exactly the same thing. If your local mechanic is the goods im happy to drive to Sydney and get him to look after my truck. Ive been burnt way too many times and just want someone to look after my rig that I can trust!!

He always has a D3 box in stock ready to go, but the trap is the mechanic has to ship mine first to him to service & fit the mechatronics from my box.

G'day Doddsy

About 2yrs ago I bought Dr Tranny's from Motospecs Drivetech in Stafford Qld.

Cheers

My 3.0 D4's box is still spitting the dummy with P2704 when trying to engage 5th after dropping back under load from 6th in both auto and manual mode, even returning to 6th by itself when in manual at less than 2000 rpm. Adaptations were re-learnt after having got clearer instructions on the learning procedure but still no improvement. I have a few more inquiries to make but may fit a new set of solenoids as there's no indication of plate wear, all clutch adaption pressures and timing are identical and it up-shifts and down-shifts smoothly apart from failing to engage when dropping back to 5th.

A USA 2010 RR owner reported the same fault code in the same general circumstances 10 days ago but no diagnosis yet. New solenoids wont be the solution if the prematurely worn stator bush mentioned in the TSB is indeed the cause.
