Weird transmission behaviour 2008 Multivan 6 speed auto

[Silver Caravelle]

G'day all,

In the last week, I have noticed some odd behaviour with the auto.

When off thottle and back on throttle in drive (more noticable around the suburban streets in the lower gears), there is a distinct delay/hestitation and very slight clunk whilst picking up again in drive. Not turbo lag or engine flat spot or engine/transmission mount issues. No external loss of transmission fluid.

At 55,000Ks, is this a sign of an Auto about to cost me many thousands? Maybe a sticky solenoid in the auto?
Any initial thoughts appreciated before heading to the dealer to check for fault codes.

Thanks,

Scott

Get the ATF changed at good AT specialist in your area. He should also be able to check for any faults.

Thanks Transporter. I had planned to get this done at next service or one after.

Smooth changes whilst in motion and engaging drive or reverse stationary. But Noticeable delay/slightly hard shift when off accelerator/on accelerator crawling along in the lower gears.

Thanks,

Scott

Doesn't sound good... hope for your sake we won't be adding another failed a/t to the growing list. Mine failed with very similar km's and VW came to the party with a 50% goodwill claim even though it was out of warranty. A fluid change is unlikely to help if internal components are already worn. Make sure they check for clutch material in the fluid.

Might be a long shot, but try resetting the TCM.

Best of luck.

Hi Bluefin, I have done the TCM reset. No different. It is very specific. Goes in to reverse smoothly, goes into drive smoothly and changes through the gears smoothly, takes off from the lights smoothly, no slippage. Distinct delay/hesitation (be it for a second) when foot off accelerator and back on acceleration again when in motion.

I will need to book it in to first ascertain any fault codes. Like you I reckon a fluid/filter change wount make any difference and particuarly at low ks. Might also be something related to throttle off/on position that impacts a delay in the auto rengaging in the particular circumstance. Might be a dodgy solenoid in the transmission valve body...but all guesses at present.

I will let you know the outcome.

Thanks,

Scott

I'd get it checked out, maybe get it serviced by someone that knows what they are doing.
I am whispering because I don't want Howard to see this.....fuel to the fire about VW autos and DSG's

Sprung !!!! I saw ya .

Keen to know what the solution is, this has been happening to my auto for awhile now. Basically when slowing down for give way signs, and then taking off when not completely stopped. Bit of a delay shifting into gear and feels like revving a manual car in neutral.

I've noticed it more in the morning on the way to work when the weather is cold...

Hi Silver C as you would have noticed VW autos are not on my christmas card list ours has also given us some moments as described by Lemmiwinks and your self , the main difference is that ours gives a solid thump sometimes when changing up or down from 4th to 5th coupled with loss of drive like its in neutral turn off and on and its fine again but ours is 130000 kays so maybe I shouldn,t feel so bad .

[Silver Caravelle]

Thanks all. I have yet to get it check out for logged faults. But it would seem similar (but not exact) to what Lemmiwinks is experiencing. Also most like a DSG delay!!! My does it cool or warm. I have a 500k trip on the weekend. Will see if there is any change for the worse.

Cheers,

Scott

Are of you VW specialist mechanics able to explain in simpleton terms {me} what the correlation is between the t5 triptronic auto gear box and engine management , as 3 times today I was left with no drive in the space of 5 minutes . Stopped at red light took off reving engine very slow forward movment + no go turn off [middle of intersection great] restart and away we go less than a minute later does the same turning into shops ., and then again minute later at corner turn . Twenty minutes later down to shops and it does not miss a beat , why would electronics cause the auto to go into neutral ???????????????????????

[bluefin321]

Sunny, Might be worth asking your local dealer to check if there is a TSB for the problem you're experiencing or ask them to flash the ECU. You'll see in my A/T thread that there was a TSB that exactly matched my issue and a software update was applied. I've had the van back for three days now and happy to report the gear changes are silky smooth.

Transmission problem???

How many years out of warranty was yours if VW came to party to give 50% - asking as have 2006 auto multivan 2.5TDI transmission failed on mine with only 84000kms on clock. Customer Care said I have to tow to dealer and they will advise me.

Same model as yours.

2007 VW 2.5TDi Crewvan 6 speed Auto
Hi, I changed the trans. oil (to Penrite) as suggested on another forum and had a couple of months of trouble-free motoring, then the auto started playing up with poor (mushed) upward gear changes and bad baulking as it selected the lower gears coming to a halt. I changed the oil again and found small particles of metal on the filter, reset the transmission memory but the problem got no better.Having found the only Auto Transmission repair shop in Victoria to look at the problems I took it for a computer analysis which interestingly presented no active transmission fault codes. However I was advised last july that the transmission was destroying itself and I was presented with a full $6400 rebuild!!!
Given that the van is worth squat with a stuffed 'box, I booked it in.
Now, I have no allegiance to this organisation but was extremely happy with the service I received.
The Manager, Sid Quintal has a lot of experience with these boxes and although he doesn't do too many these days he has done quite a few in the past!!!
The van was dropped off on Monday and I picked it up Thursday lunch time.
The following work was done;
New Gaskets, Seals, Rings And Oil Seals
New Friction Plates
New Band
New Oil Filter
New Bushings
New Bearings
New Servo Piston Assembly
New Aftermarket Forward & Direct Clutch Drum
New Electrical Solenoid Block
Transgo Correction Kit
Remanufactured Quality Torque Converter
Dyno Tested To Ensure Smooth Operation
New OEM Gaskets, Seals, Rings And Oil Seals
New Friction Plates
New Oil Filter
New OEM Updated Wave Ring
New OEM Oil Pump Half Assembly
New OEM Solenoids
Remanufactured Quality Torque Converter
Dyno Tested To Ensure Smooth Operation
After all the preliminary tests are carried out and accepted, our transmissions are all built in an environmentally controlled area where we ensure the best rebuilding practises are followed and our quality control is strictly adhered to. When the rebuild process is completed, all our transmissions are dyno & leak tested prior to shipping or installation and fluid filled to allow for a cooler flow check to be performed in the vehicle.
2 Year/50,000km warranty (Non Commercial Vehicles) applies to our fully rebuilt transmission and torque-converter assemblies which have all been through testing for Valve-Body/Mechatronic operation, component leak down, clearance and specification check, before being assembled. Once assembled, they are then dyno tested prior to shipping or fitting.
For those of you interested this is where I went

I had a quick tour of the workshop facility which is impressive and spotless. Interesting to see the number of prestige cars there that have endemic auto box issues that A&B repair, they have the only Australian licence to repair ZF boxes.
I hope this helps.
