Hi to everyone!

I am a V70 2002 2.4T automatic transmission Volvo owner, and almost 3 months ago I have had a problem with my car.

The problem is that when it starts to move (in D gear, in any circumstances and every time), after doing the first change, the car sometimes accelerates (slips) and makes an abrupt change to the next gear, or sometimes does not accelerate but always feel the abrupt change.

The problem has evolved from mild to sharp. The car does not give any error on the board (aside from the urgent air bags).

As additional data,
- I replaced the ATF in August 2011 and put a Mobil ATF. Before that the car was showing this problem, but very mild and very sporadically. Now it is every day and very abrupt.

And as an aditional note, want to say that I found code 025 in my car after doing the next:
- when my car is off
- I inserted the key into the starter
- turned key to first point
- pushed the trim button for a while
- turned key to next point
- the code 025 appeared.

I was reading about replacing solenoids on the gerbox, but i'm not sure if that is exactly my problem and if it will work?

I hope someone can help me.
Thank you!
