Transmission judder what's the best option
My 2009 D3 Aato with 130k miles on has started juddering at 50-60mph, usually uphill with throttle applied.
I have read that ultimately the torque converter is on it's way out and I will need a new one eventually.
The service history I got with this car shows it had a megaflush done 3 years (25k miles) ago so I suspect the previous owner had the same issue and was able to sort it with the flush.
I've decided if I can extend the life any further before I have that big cost I'm certainly going to try.
Can I get some opinions on what the best option is:
a) Throw in a £15 tube of Dr tranny.
b) Have another megaflush done (or DIY do an oil and filter change with the pressurised method seen on these forums)
c) both?
What's the concensus, can I get some more life from this transmission?
Thanks,
Andrew

Hi
Hope u don’t mind me mentioning it but have u also checked the propshafts centre bearing , prop UJ’s, tyres are balanced, tyre pressures, wheels bearings , wishbone bushes are also ok
Regarding the torque convertor does the revs rise like a slipping clutch or just the juddering plse
Have u had the codes read to see if anything is stored
The more knowledgeable members should also be along to help u further
Hope u get it resolved without too much expense

Hi,
Yes I've checked over the driveline, the rear prop is a new GKN unit.
The revs don't rise like a slipping clutch no just get the juddering.
No codes.
I've ordered 10l of oil and I'm going to try the flushing technique shown in the guide on these forums and see if it helps before putting any Dr Tranny in.

To throw in my opinion..
“Life” extenders do cost money too AND while they sometimes do “mask” the real problem.. wear is there and can and will damage parts who are possible still good at this very moment …
Dr. Tranny is for me the level of roadside repair… gets you “home” but needs real attention ASAP.
If you wait, the autobox itself, valve blocks etc. Are in need of attention too in the end, there fore much much more expensive
I had the same judder at basically the same mileage, replaced the TC, new oil, and mounted a replacable filter.. smooth as new… and after 30.000 km’s now, still smooth as new… Best regards

Motolab makes a very valid point if you are covering significant miles & plan to keep the vehicle for a good number of years, You will end up deferring the problem & in the long run it will cost you more.
I had the same issue with my D3 not long after I purchased it. DrTranny instantly resolved the judder & whilst I was only doing 3/4000 miles a year it solved the problem whilst i own it. Ultimately though the torque converter was worn out & will eventually need replacing.
