Question about 1991 Volvo 740
Check the oil level of the transmission
that transmission does have an overdrive relay
that relay may be faulty
get the transmission serviced and if found in bad condition
cheapest fix is
source a good used automatic transmission and have that fitted in
cost of a full rebuild on these transmission is more than the volvo is worth
its a lot of km./miles
sounds like the third /overdrive part of the transmission
is slipping or worn

Run the engine til hot, check the transmission fluid... If it is dark/dirty red and smells bad, it needs to be changed. If it hasnt been changed in your knowledge in the last 40,000 miles, change it anyway. If that doesnt fix it and the fluid was very smelly even after u changed it and ran it for an hour on the road, the trans may have to be rebuilt. There are some treatments you can add and many do work well, so go to autozone or Napa and check em out. I would recommend high mileage additives anyway if the mileage is high as you'll get more life out of the transmissio...hope that helps...if so rate me..

It may be a faulty relay - usually behind the radio - it makes a clicking sound when you hit the button on the shift lever. Or it may be the overdrive solinoid which is mounted on the top of the tranny. Check all of your connestions first. One other thing - the wire from the shift lever overdrive button to the overdrive solenoid on the tranny may run over the top of the drive shaft - check for wear

Yes....check your fluid level. It sounds low. Does it do it in a turn when you step on the gas as you are turning, slip?

SOURCE: my 91 volvo 740 won't start
Could be that there is a clog at the tank-there is a screen there- can be accessed through access panel behind rear seat- also try taking off fuel line at engine and starting engine--if there is fuel present then I would rule out the tank screen problem. Good luck--let me know if that helps. C
