one of these two (the things with springs) has popped off
Thanks for this post, it has helped!
My gears have just gone, but the two linkage arms with springs are still connected, they have not popped off, but the gear stick is still loose and not engaging any of the gears correctly.
I can move the top linkage arm left and right - with the gear stick moving and clicking into gear but the stick is still loose.
Any help greatly appreciated.
