Tiptronic transmission thumping when selecting gears when cold

[Bayman]

Hi all,

I was hoping someone could advise the best way to go here with a Golf V 2006 model FSI with a 6 speed Tiptronic transmission that has suddenly begun thumping (surging) into gear when selecting gears when cold. Eg Park to R, or D.

The oil has never been changed but I now read VWA recommend a change at 60,000kms. Fortunately the car has been servided at a VW dealer all its life and just missed the update on the trans oil change but we have Allianz extended warranty valid on it. The dealer says they will most likely remove the transmission from the car and we will be without the car for 2 weeks!!!. The car drives ok when warm (after 3 mins) so I wonder if a valve is sticking, either way sounds bad. The Golf has done 79,0000kms.

Has anyone been down this path and we also have a Tiguan with the same transmission so I think I will be getting the oil replaced next service well before their lifetime sealed unit of 60,000kms.

Thanks in anticipation!!

Are you sure your Tiguan has the same tranny? The MKV 2.0 fsi has a conventional 6spd Automatic where as I thought all tiguans have a DSG box which is very different.

Also where did your allianz warranty come from? I personally wouldn't trust any warranty but a vw extended, a lot of those 3rd party extended warranties are as worthless as the paper they are written on when it comes to claim time.

The Allianz warranty IS the VW extended warranty.

Yes I have been down this path. Mine was a DSG tho, just had a rattle and they sent it to Sydney for a full rebuild. Cost Allianz $18k! Probably last forever now and now Im gonna sell it.

Oh and try about 6 weeks for a rebuild!

Yes it is an Allianz, confirm with them direct, they answer the 1300 phone as VW insurance.
Tiguan has Tiptronic in MY09 & MY10 I think MY11 was when they went to DSG.

Thanks

I have found what seems to be my issue here:

If shifting is erratic, slow, or harsh, if your car is fuel injected, you probably have shift solenoids. The valves in these solenoids may be sticking. A good place to start is to service the transmission, and add a good shift conditioner. If it doesn't solve the problem, you may need to replace the shift solenoids. The same holds true for older transmissions. The valves may be sticking in the valve body or governor. If so, it's service, and/or replace the valve body and governor. It's also worth mentioning that built into the transmission, to help cushion the shifts are accumulators. These are spring loaded dampeners. If they fail, the transmission will likely "slam" into gear. It will be a quick, neck-breaking shift, not harsh or delayed.

Now would anyone care to comment on what is the main reason for failure here, oil too old? filter clogged? bad design?

And obviously the cost and work required to fix it. Extended warranty hopefully will pay for it all.

Theres no point trying to trouble shoot the trans (if its a dsg) they are a sealed unit. If you have dodgy gear changes its either the mechatronics unit or the dsg and either way they just replace them at huge cost. Its a well known fact that the dsg has had issues, in some countries like the US it has had full recalls.

VW have been known to skirt around the issue except when its out of factory warranty and Allianz has to foot the bill, then they just fix it and charge allianz.

I am just trying to ascertain what may have gone wrong and what could have avoided the gearbox crashing. The Golf V has a Tiptronic Slushbox NOT a DSG. I know the DSGs can be troublesome. My point of issue was that VWA changed the servicing intervals of these gearboxes about 12 months ago to include a oil & filter change at 60,000kms. Our dealer never informed us nor did they suggest to do it when the car was last at the dealer for rear brakes o/haul. The Golf has nearly 80,000kms on it.

As there are millions if these Golf Tiptronic autos around, I just wonder how reliable they are and thank goodness we took out the extended warranty. I am forming the opinion that owning any VW car without a current warranty or extended warranty is just too much financial risk, especially considering the value of a vehicle over 6 years old and the advantage to buy a newer vehicle as aginst the rip off prices for any repairs. Sort of defeats owning a diesel and their longevity.

Thanks for the heads up on Allianz and there attitude to gear box repairs.

Car goes in Monday for assessing the problem, claim with Allianz.

The automatic transmission (Non-DSG) can be opened up and repaired. They're pretty much a conventional auto.

I have replaced the valve body in one in the past (Around $3,000, but way cheaper than a complete transmission). Bare in mind, this one had reletively clean, uncontaminated oil. If there's swarf/metal shavings in the oil, the transmission will need to be replaced.

I would say it will need a valve body in your case.

Thanks for that info, the dealer says they will remove the auto box and take it to their auto tx repair centre off site (Bayford Motor Group) not sure if it outsourced repair. Service manager at Sth Yarra VW suggested it might be a valve body. I hope to get some feedback on the condition of the auto tranny. Is it common for these to play up at 80,000kms? I am wondering whether to have my tx oil replaced at next service but 60,000km is only 18,000kms away so I figure a change at 30,000km in hindsight might have been the right thing to do, bar the cost of it.

So can the valve body be replaced without removing the whole tranny from the vehicle?

Thanks,
Bayman

The Tiguan gets it's non-DSG oil change at 60,000klms. It has been suggested that these are a little more robust than the previous incarnations.

The one I repaired had 130,000klms on it, from memory.

I don't understand why your dealership needs to remove the transmission, only to send it away for repairs. The job can be done quite easily in the car, in only a couple of hours.

I'd shop around.

Thanks for the advice. I'll question them more, this is what a service advisor told us on Friday.
So do you reckon the average Dealer VW technician is capable of diagnosing and fixing a valve body? If it takes 2 hours the parts cost must be horrendous for a $3000 job. Allianz will be footing the bill so they won't want excessive repairs. Is it fair to say most auto problems the dealers handle are straight auto swaps with new transmissions, any tinkering is left for auto specialists (ourtsourced). I'll talk to the service manager in the morning and pin him down on exactly what they might do.
