1992 Volvo 940 Question: transmision not shifting into o.d.

You need to be careful about replacing parts on this system. If any of the wiring is damaged it could be causing a short circuit, and it will damage any new part you install.
Can you explain what the symptoms are regarding the OD light? Is it lighting up or not?
