Thanks all for your advice. Have since been in contact with a main dealer and was able to speak to a mechanic. Firstly he said to re check gearbox oil level, and to make sure my mechanic hadn't mixed up electronic cables from the box itself. This info I passed on but everything seems to be in order. Luckily my mechanic is a friend of mine and has a good record with fault finding. Will keep you posted, maybe my result will help someone else here. Thanks again to you all.

Have since found out why the car will not drive. My mechanic test drove the car on completion of the work after which a piece of the oil pump shattered. Was in contact with a gearbox specialist to discover it could have happened myself after getting the car back. His initial concern was that my mechanic had done damage, though I found this was not the case after speaking with both. I am currently waiting to have an oil pump fitted to the gearbox by the gearbox firm and am confident that this will end my troubles. Will post again when the car is up and running.

I have S80 AW 55-50sn and when the transmision is in normal temperature than the shifting from 3-4 or 4-3 is bad. Started sometimes but now it is realy often. Also I have Neutral to Drive delay, often with a bang engagement. Reverse engagement is OK.
I know the 3-4 is comanded by S3 solenoid. But I dont know what could be wrong.

I'm sorry about my english.

I'm looking to buy another volvo and I'm considering the automatic gearbox versions with geartronic as well. Is there any way to test the gearbox when I check the car?

Apart from checking the oil level and the colour is there anything else I could check?

Cheers,
Matt

that it drives in all gears, the auto change is smooth without "bangs" or "clunks", that the kickdown works , and that you can manually select all gears without it clunking/other
If there is a "S" "E" "W" buttons, check they work and that the light (if any) on the dash lights up

As Andy has said but you need to be able to test drive it for at least an hour or you will miss any problems with the box, when they are cold they generally work like a dream but once they are hot thats when you get the flaring and bumping (if they are faulty).

Heres a Question.
My 2001 V70, Drives fine through all the gears, up and down, Kickdown is fine too. The problem i have is when i stop in traffic, take my foot off the brake to pull away and instead of the car Gently pulling away, it will hesitate until the throttle is applied and then "lurches" forward. It happens 8 out of 10 times no matter how gentle i am with the throttle..... Hard to explain accurately but its almost like its forgetting it should be in drive and quickly chucks it into gear creating a Cluncky lurch forward when throttle is applied.
No aparent noise when this happens though.

Oh my Servo has a bit of a "hissing" leak will this be the cause ???

Any ideas ????

Do a search on this forum for "stop netural", it needs a dealer only software update to remove this feature.

Replacing the servo on right hand drive cars is expensive as the engine has to be dropped down a few inches.

MarksV70 · Jan 12th, 2011, 15:20

Cheers mate. Have had a couple of suggestions on how to avoid the issue until i get the software upgrade done.

Regards to the Servo, Theres a good Volvo Breakers in Preston who did my Engine change, So il task them with the servo job.

Thanks again

Was told by gearbox specialist that the AISN geartronic unit fitted to my 2002 XC70 was not at all reliable & the oil pump (I don't know about the gearbox) is actually shared with the GM Opel/Vauxhall Vectra 2003/4 model. Have got my car back with 2nd hand oil pump working fine.He says oil pump for 5 speed geartronic not available new. He charged stg£400 to fit 2nd hand pump. Hope this is of some information.
