volvo 940 GL 1991

Sometimes my gearstick of my volvo 940GL is completely locked-up. I am
looking for the reason.
It is an ordinary gearbox No electronics involved.
Does somebody recognize this problem and how to solve it

 

Ordinary gearbox as in manual transmission? The US models are all
automatic but if you are elsewhere it could be either. We need more
details, under what conditions is it locked up? What gear is it stuck in?

 

In this case (holland) it is a manual gearbox.
It lockes the gearstick driving in the 5 gear while releasing the
accelerator pedal, decluth and trying to gear down.
I have to declutch and bring the car to standstill.
Then I switch off en on again and then I can choose the first gear again
and move on

 

What happens if you start the engine, depress the clutch, then shift
into reverse? Does it grind? If so, then your clutch may not be fully
disengaging. If that isn't it, it sounds like you have an internal
gearbox problem. Is it only 5th gear that it gets stuck in?

I'm envious of those places that got manual-equipped 900's, over here in
the US if we want one, we have to make it ourselves, and the M90 gearbox
has to be imported from Europe.

 

I am very pleased with your attention.
Indeed it happens sometimes also in other gears
and it grinds shifting into reverse sometimes too.
I understand that I have to find out if declutch is oke.
From other parts of the internet I also found remarks about the oil level in
the gearbox. I will look into these things.

 

Yeah it really sounds like your clutch is not disengaging fully. This
could be the pressure plate, release bearing, clutch fork, or the
hydraulic system. It's hard on the gearbox to drive it when this is
happening.

 

If the clutch checks out OK and is correctly adjusted, the next thing
is to drain the fluid and replace it.

Try Redline MTL.

 

I've had good luck with MTL, however this problem sounds much more
severe than old fluid. Either it's something simple like the clutch, or
there's something actually broken inside the gearbox.
