Hi!

I'm the new guy in here, so pardon me if I'm writing
in the forum i should not, anyway I've got very
important question to all 850 users. (with auto-tranny)

My problem:
After I changed the ATF in my transmission it started
to act in a strange way. Sometimes it shift realy smooth
but sometimes It realy shakes!!! For example: the last
weak I drove about 200k and nothing realy happened,
only when I was going about 120k/hour it felt like
the tranny could'n decide whether to stay on the
4th gear or put to the neutral. (I was pushing the gas very
gently - maybe that's why)
Today, when I started the car the flashing arrow apeared and
it showed 1-3-2 code (ECU fault). I reseted the fault code,
and it seemed to be OK, but when I drove it started to shake
again. Do you have any suggestions? What do you thing
might happen? The oil level is OK, the color of the ATF is OK too.

The problem gets even worse, becouse there is no good Automatic
gearbox shop in the place i live. I could buy a new or
not-very-used transmission but do i realy have too?

Regards,
Chriss
