V70 2006 Auto box clunk

[Mattye]

Hi all,
My 2006 V70 AWD auto, 136000 miles, has just started to clunk when going from P to R and also on some of the gear changes from 2nd to 3rd. Its quite noticeable when in the car and clings and jerks forward a bit almost like the gears are just being thrown together rather being selected and meshing.
I have just changed the auto box fluid and been for a 30 mile ride but this doesn't seemed to have improved the gear change any.
Could this be a sign of the clutch on the way out?
Does the gearbox need time to account for the new fluid?

Any thoughts appreciated.

I have searched for similar issues but can't find anything conclusive.

what colour was the fluid you drained it should be red it may take a couple more changes before showing any improvement. have you reset the fluid counter/ or re set the adaptations. have you ever had any software updates at a dealers.

Hi Simmy,
Don't think the fluid had ever been changed as it was a really dark colour.
No the fluid counter hasn't been reset. I guess this is done via the Vida software?

[Simmy]

if you just changed abt 3 ltr that is a small part of the total amount. i think the g box and torque converter hold abt 8 ltr in total. so a few more changes should clean it up .yes vida is needed to reset the counter and do the adaptions . ask for a local member who has vida to help .

You don't say whether it's a petrol or diesel so we don't know whether it's a 5 speed or 6 speed TF80 transmission. If diesel, grey or black engine cover ?

Mine is a 2.4 D5 with 6 speed auto.

Does anyone know how to reset the transmission fluid counter in VIDA?

Just a quick update.
Once I had completed the fluid change and without resetting the counter in VIDA the gear changes were much smoother. I think the software re-learns the values comping from the torque converter over time.
I then managed to get my VIDA and DICE up and running and I have now reset the transmission fluid counter. I hasn't made a great deal of difference to the gear changes but at least I know the counter is reset.
I guess my comments are whilst it is part of the official procedure to reset the fluid counter the software will adapt to the fluid and smooth out the gear changes.

I think your at a stage where you have to balance potential repair costs vs the age of the car tbh, I've been an auto man for many decades and when I had the older Vx automatics I knew they had to go before 70k and 100k from the outset, the newer boxes do better miles but like anything they still wear out.

I hope you are right and it settles down but if it doesn't I'd be very wary about chasing it with the wallet.

And if you do chase it with your wallet, do it once, right.
Without knowing the particulars of your transmission I'd respectfully suggest a full rebuild of your own unit WHEN THE TIME COMES.

Fluid refreshments have been known to work wonders. If a little damage has ocurred, you may, as many have before us, be able to live with it. Anticipating a shift and letting your foot off the acellerator so worn parts are clamped together a bit more softly (if that's your woe).

Hypothetical from Across the Sea: If a complete rebuild cost $5,000 and lasts you 4 years, you're spent $104.17 per month.

Me trying to sound intellegent: Since well before Covid I've been telling people to keep their current vehicle as long as they can and to buy whatever "next tech car" is available then.

It seems nothing's quite that simple. Price gouging is rife and the data available from the range of tech (100% electric, economical hybrid, performance hybrid) is really just coming in.

Auto makers have been rushing to build some kind of higher tech vehicle and have taken whatever shortcuts they can. They also want to hit a target customer base which somehow jibes with their particulat assembly line capacities. That means marketing tickling, not what our needs are, are dictating decisions. That's bad for the general consumer.

One bit of good news is that Tesla is lowering their prices (in No, America, anyway). To me that means the flow of the more financially insulated among us into Tesla dealerships has begun to slow. Next will be the adaptation of this tech to cars which are more normal. Loosing some of the neck-breaking acelleration and turning it into range or carrying capacity would be nice.

Keep your car for the next 5 years.
