1987 Volvo 760 4 cyl Two Wheel Drive Automatic 129700 miles
on my 1987 volvo 760 turbo. My overdrive wont engage I changed selonoid, I changed the relay, I changed the overdrive button. I tested for current to the selonoid and cant get one, but there is current into the relay, but there is none coming out. What would cause this and what can I do to solve this problem. Thanks luke.
