V70 2.4T 2003 - Transmission

I have a 2003 V70 2.4T with 37,000 that I purchased in from a Volvo dealer 2 months ago. Soon after I noticed what can be described as stumble or hesitation between 3rd, 4th and 5th gear. On a moderate acceleration, easing up to a 45 mph speed limit, the transmission will stumble as if it is trying to decide between 4th or 5th. As the throttle is lifted and the car goes out of 3rd it tries to settle into 5th only to realize that the car does not have the momentum for the engine to move the car along comfortably so it tries 4th only to find that the preferred efficiency is in 5th and back it goes. (or some variation of this). It does this for no more than a second or two and then it passes. This only occurs under the situation as described at or near the 41 mph mark.

Of course the overriding concern is that a major problem in imminent. I would like to think that this would be the type of problem that a software upgrade would resolve. It really seems as though the computer can’t make up its mind.

I did have it back to the dealer be could not replicate the issue on a test drive. I does not happen consistently but it does happen often enough (4-6 times per week) to be described as a real issue

Has anyone encountered a similar problem and discovered fix? The service department at the Volvo dealership is keeping their mouth shut regarding any know issues and giving me the “you are imagining it” look. I would normally run to an independent shop but and fairly convinced it could be a known problem when they sold the car as they were the original dealer and have the full service history.

Any input is appreciated.

Cheers

You mention that you think it's a software upgrade cure, and I think that's your next step if it hasn't been done.

After going back to the dealer for a second time the story was the same. The tech did tell me that he notice the fluid was a little low and that he topped it off. Strangely it seemed as though the issue lessened. No idea why the fluid would have been low...no leaks anywhere and I havent tried to learn if the trans is orginal or has already been replaced. The better news is that I only feel the issue a few times a month now... Now I am wondering if the adaptive transmission has adapted. I don't fully understand how this is suppose to work over time and cat seem to get a good explanation... The end result is no clear resolution at this time but I am not leaving puddles of fluid or parts on the road...

Hi ,had trasmmition problems with a bit of sliping and a bit of gear wandering,My Dealer could have done a trans upgrade
through the computor,but elected to do ETS,ETM/ECM upgrades as well as a trans flush and refill seems to have resolved
the problem,if it didn't a trans upgrade would have been deeded... Fingures crossed..

We had some issues with the transmission on our 01 2.4T and ended up getting the transmission replaced. I think I read somewhere that is was common in a lot of Australian v70s
