this might be encouraging ..
remove the aft end of the shift linkage from the 'lever with a ball on
it' on the side of the trans. ( two nuts and bolts to undo that part )

check, with a deep 13mm socket, that the 13mm hex nut holding the lever
onto splines there, is good and tight.
I've found loose ones a buncha times.
If that's loose there, not only will it result in very vague gear selection,
left loose long enough ..it will damage the splines in the lever.

while there, lube it really good.
I use 'black slimy' grease...ie. moly suffide I think it is, on that ball.
I kinda prefer the rubber boot there to be semi-shot so I can spray nice
lube in there. ....regularly, not every 7 years when things aren't
working right. lol.
