Thanks for the input. It ran fine after the first drain and fill and fine after the second one also, which was done on Saturday. But driving home from work today, about a 40 mile commute, I noticed the down shifting being king of jerky. It has been smooth up until now. That is what concerned me. Bas...

The continuing saga...for me. Rowing the shifter fixed my last problem and got the arrow to go away. Car has been driving and shifting fine as far as I can tell. I still have had the 4th gear incorrect ratio code. Am I damaging my transmission by continuing to drive with this code? So I did a drain ...

Thanks for the tip on the water pump. I'm hoping the non-Dealer Volvo guy around here will let me provide my own parts and just charge labor.

Wish me luck on the flush this weekend.

I'm trying to not stick my head in the sand over the PNP switch but I don't think I'm qualified to do the cleaning myself and can't pay to replace it right now. I am going to do some kind of flush or drain/change this weekend. The car is not having issues right now but I wanted to do the transmissio...

My 850 wagon has a cd changer in the glove box but it is missing the cassette. I don't really need the changer and would rather have the glove box space back. The thing is I can't figure out for the life of me how to get the changer out. I can't see any screws or anything holding in. I tried to push...

My Volvo has not had any of the same issues since this happened and I found out the code. Now I am getting P0734, gear 4 incorrect ratio. I think I am going to do a trans fluid flush this weekend. Since I don't have all the tools and parts to the the modified flush described on this site I am think ...

Thanks I found the PNP write up. I would probably do more harm than good trying all that. I'll find out what code I have now.

I did it 25 times That got the arrow to stop blinking but now the check engine light is on.

Thanks do I do this with the engine running or off?
Also, should I go to the dealer or Volvo specialist and get a flush ASAP???
Any other suggestions if that doesn't work?
I really cannot afford a major repair right now. I can do a flush but that is about it.

I recently acquired this 850 with about 153K. It has been driving really good until tonight. I pulled out from a stop sign and suddenly had very weird shifting going on. It started shifting at weird times and just not feeling right, making weird transmission noises. The check engine light came on an...
