Well, I´ve solved a lot of problems with the group help.

Now I have other that I forgot:

My car is a 850 GLT 93, with automatic transmision.

When the engine and transmision is cold (two or three minutes after
started in the morning) doesn´t shift to second, third, etc., gear.
Sometimes one or two minutes after that the "service light" goes out is
when it starts to work normally.

Once it gots warm, shifts with no problem at all. But if I press winter
or sport mode, while being cold, the shifting stays crazy for about
three minutes more,

Some idea?

Best regards
Oscar

This model had AT problems. Mine died by not shifting out if 1st and
then loosing all power. The first generation ATs in the '93 850s would
usually go between 80,000 miles and 120,000 miles. Mine made it to
120,000 miles. The fix was a rebuilt transmission. Other people had
different experiences. I would recommend having the dealer check for
any codes. You may be lucky and just have a small problem, but I
wouldn't plan on it going away.

Hi,
be carefull to not drive the car while in winter-mode!!
I would try to replace your AT oil with dextron III or whatever is recommended
by Volvo, maybe it will help?
You might have too little oil, as then the hydraulic pressure wont be high
enough, untill the oil expands due to heat?

Just my thoughts, I'm not a mechanic!

Hi Olav:

Both two recomendations have full sense. I´ll try tomorrow changing
the ATF.

I tested if the transmision is loosing power or if it is slippering,
but no, THANKS. I could burn front tires having it in 1st and park
brake full.

So, it seems that it is a low temperature problem but not a wearing
mater.

Best regards
