The Torque Converter Auto (NOT DSG) T5 thumps into drive when cold

[Rebuild]

oil level checked out ok, BUT...
for 23K since last partial change, doesn't look real good to me.Old on left, new on right


So, i've opened it up and doing fluid again.Decided on Penrite ATF FS for refill, after emailing Penrite, as DXVI isn't available anymore
Pan has a little more junk than i would like, filter is mostly clean.
Adelaide weather isn't helping today, want to measure solenoid resistances if possible, while it's open.

[Umai Naa!!]

What does it smell like?

Burnt?

Good point Umai , when I had ours rebuilt the guy would not do the job unless I fitted a cooler at the same time . I agreed without hesitation as I still reckon the sealed for life was ignorant of the sort of conditions we have here in Australia .I don't know who designed or built the boxes but they obviously don't live in the real world . There is no way any fluid can retain its viscosity with out degrading through heat and wear and tear if its never changed !!

Any metal filingsin the old oil maybe get a magnet , although I would imagine most of the box has alloy components .

doesn't smell burnt, magnets have a little fuzz.More concerned with the junk in the pan, like little blackish specs, not solid or hard, maybe it's some of the fibre plates.Don't remember much like that from the previous changes.

[Umai Naa!!]

See how it goes with the fluid and filter chance, and maybe give it a reset as well.

If it's still thumping into gear, you'll need to rectify it. Don't keep driving it.

Japanese auto built by Aisin. Not worth the heartache to go through why factory service schedules never listed transmission fluid changes...but it would be interesting to see if the same box in Japanese passenger cars had the same service guide?

The auto vw specified to use in the transporter /mv looks to be a built to euro spec small car transmission that vw has stuffed into a heavy van to save money. The other cars it’s listed as used in are 3cyl bmws a mini , Skoda the Tiguan and Jetta , all about half the weight of a transporter .

Hmm makes sense then why the oil would get burnt trying to lug a heavy van with load around without a regular service .

I don't think that is strictly correct.There are different model designations within the TF60 codes.Some of the VW ones are 09G/09K(Transporter)/09M
They vary in torque ratings and as such have differently designed internals (eg TC sizing, gear config, bearing sizes,etc)

Anyway, have finished my oil change.Still clunks at first into Drive, maybe not as bad. If i then go straight back to Park, then Drive, doesn't clunk.Almost as if it needs to build up pressure on the first selection or something
Gearchanges are definitely smoother.

This is the pieces i found in the sump.On closer inspection they feel like small rubber particles or something.


This was the filter after 23K


My dodgy resistance checks, not even sure i did it right
N90,N91,N92,N93,N282,N283 two wire solenoids measured around 4.6 - 5.0 ohms
N88,N89 single wire solenoids both 11.4 ohms
from my googling, only the 93 and 283 two wire ones should be 1-5 ohms, the others should be 9-24 ohms.
The 88 and 89 should be 9-24 ohms, mine seem ok

Yes, i'm going to keep driving it for now

This was our filter on removal the black sections are supposed to be the filtering parts which are obviously completely blocked , the clean bits are actual resting on the metal base of the filter where no fluid passes through .

Not so much strength but more that they should have built the box so it could be serviced .

It can be serviced. The oil and filter change in this auto transmission is not any different to 99% of torque converter transmissions.

[Umai Naa!!]

Exactly.

Yes you are right Transporter but originally VW dealers would not even considering doing a service , I would love to know why they suddenly changed . They were not built to be serviced they had to make certain parts that could be fitted to carry out the service as it did not exist before then , some transmision places would have worked out they could do them but VW just refused .

I think that filter and gasket kits were available, the same as for the Aisin transmission in the Touareg2 - lifetime fill if you’re asked the dealer and genuine filter and gasket very expensive. Still you could buy an aftermarket service kit and change the oil in them.

Though, I’d like to point out that the last van that was fitted with 6sp. tiptronic was made more than 8 years ago.
