Shift indicator light comes on and the car will not shift higher than 2nd gear. on 1990 Volvo 740

First starting in the morning, the shift indicator light does not come on, but after driving awhile, if I turn off the engine and restart the engine, the light comes on and will not go out and the auto-transmission will not shift past 2nd gear. If the car sits at work, when I leave for home the light stays out unless I have to stop and turn off the engine for something, then the light stays on. I can only drive about 30/35 mls. What can cause this problem?

Couple possibilities. The overdrive relays often stick and cause the light to stay on, but this will still allow it to go into 3rd gear, just not 4th gear. Are you sure you're not getting 3rd gear?

You are exactly right, its 4th gear that it will not go in. Thanks for your help.
