Anyways I was planning on changing the transmission oil hoping it might help with the gear stiffness. I'd like if someone can confirm that the transmission that my car has is MTX-75?
I found a few transmission fluids and am not sure if they are good for the car so I'd like if you guys could confirm it.

If I'm in the wrong please do tell what I should look for and any ideas why the reverse problem accured?

I cant see how changing oil will make it easier to select gears?? maybe the cables need adjustment ...

Volvo use the finest synthetic oil so as long as it is clean it will be fine.

The problem it wont go into R sometimes when the engine is stopped is the straight cut gear wheels did not stop in the aligned position..
