The car starts and runes fine in the mornings which have been cool. My drive
to work is short so the gearbox doesn't usually heat up a lot. Lately during
longer trips the transmission starts to exhibit problems.
1.downshifting harshly during an aggressive stop
2. accelerating away from this sort of downshift is like the gearbox is
spinning but not engaged, car moves into gear abruptly and drives as normal
3. The worst seen to date is that the car was in gear on a residential
street, warm car, warm day...I could rev the engine, and not really move
faster. The car did also shift 1-2..?? Parked car for 45 mintues and drove.

Does this sound like a diagnosis can be made quickly? Is this a $100 problem
or a $1500 kind of problem?

Thanks

Doesn't this seem like a tired old clutch? But no you say it's automatic
transmission, right?
This model is probably controlled by computer(s) You need to visit a
specialist, but on the otherhand another Volvo enthusist might well
respond here Let's hope so.
Gheez the 240's didn't have this kind of problem?
 
May be the PNP switch. As a quick possible fix, with the car off,
take the gear shift and ratchet it back and forth from Park to L a dozen
or so times very rapidly. This can have the effect of cleaning contacts
that get very little use and allow the circuitry to function. Hope it
helps. If so, at least you know its not a tranny rebuild.
 
Yea I've read about the PNP, I'll try that before I take off for the mech.
on monday.
