93 240 Stuck in Over Drive

My 93 240 seems to be stuck in O/D.
When I press and de-press the O/D button the
light on the instrument panel lights and then
turns off when I de-press the botton. But the
car does not seem to be effected. When I go
about 50 mph the car seems to not switch into
final gear, but seems to be holding back like the
O/D is stuck on.
Any advise would be greatly appreciated.
Thanks,

If it does eventually shift into the top gear, the OD wiring and solenoid
are probably fine. I'd start by checking the kickdown cable to see if it's
binding.

 

The overdrive should be on all the time. Unless you might be pulling a
trailer in the mountains.
if it isnt coming on could be the switch, wireing, relay or solonide.
Check IPD Volvo after market dist
they now sell a blank to replace the solonide so it will stay on all
the time.

 

My mistake....The O/D is stuck OFF. And it won't turn on.
I will check the relay right now....

I looked further into the problem and the relay switch is
working correctly. What it really seems like is that the
car is not shifting into final gears, sort of like its stuck in
third? This is an automatic 240.

What is the kickdown cable? Where is it located?

I checked the relay and swapped it with a second 240, it is fine.
The car seems to get stuck in 3rd gear?
Thanks,
