Hello fellow V70 drivers!

I've had problems with my car's transmission for over a year now and so far I have not found a proper solution. Today I came across this forum and it seems to be the most comprehensive source of information on various Volvo issues on the net, so perhaps somebody here has noticed a problem similar to mine and can suggest a fix.

The car is 2001 V70AWD (not XC) with Geartronic transmission. The car has now done about 132,000 km and the problem started to occur at 105,000 km. Basically the problem has two ways of expressing itself. First, the computer warning light comes on and says "Transmission service required". Second, the gearbox occasionally acts weird -- sometimes the upshifts are late and engine revs get unusually high during acceleration; sometimes while standing in traffic, the car seems to want to "jump" into 1st while my foot is on the brake and I have to press the brake pedal strongly to avoid the car starting to move against my will; sometimes the car hesitates to start accelerating when I lift my foot from the brake and press the accelerator (for a second the car just stands and then "jerks" into motion).

The odd thing about this problem is that all these symptoms come and go and they are not directly related -- the computer warning sign may come while the car is behaving normally, and unusual gearbox activity may occur while there is no warning sign on the computer.

I have been to my local Volvo dealer a couple of times with this and they have told me that the error code refers to a mechanical fault in the gearbox. Their suggested solution is replacing the gearbox and they have clearly stated that they cannot repair my existing box. Since replacing the gearbox would cost me about 7,500 USD, I am not very excited about this. The problem has not prevented driving (I have done over 25,000 km since it first occurred), so I have treated this as an annoyance and not as a very serious issue. Nevertheless, I would like to know if there could be a less costly solution to this transmission problem than replacing the gearbox.

Any ideas?

Sincerely,
Jaanus T.

QUOTE(Tech @ May 9 2005, 07:10 PM)Do you know if the dealer has the latest software in the transmission?
Sounds like it might be a valve body issue.
The Valve body can be replaced on these cars.
That might and might not fix the problem.
Do you know if they disabled the nuetral control function on your car?

I expect that nobody has touched the software controlling my gearbox, so I'll ask about an upgrade next time I go to the dealer.

Is the neutral control function also a software issue or does disabling it also involve some interference with hardware (disconnecting some electronic component, etc)?

I do not know much about the mechanics of an automatic gearbox but I understand that the valve body is the core component of the system and quite a complex one too. This suggests that the replacement of the valve body is also very expensive and I wonder if it will be significantly more cost-effective than replacing the whole box.

After all my searches in the various internet forums, I begin to have a feeling that I know more about the the possible causes of my gearbox problems as well as the potential fixes than the guys at the local dealership with all their diagnostics equipment and training. I hope that this is not the case
