To-Do list: Difficulty finding fifth gear; loss of reverse

Alert me when someone posts in this thread:

Hi everyone,

I'm trying to develop an ordered list of what to check as my 88 900 na, which I've just gotten on the road, is having the following issues. I am thinking that they are related.

1.) fifth gear is difficult to find. Often I have to blip the throttle w the clutch in for the gear to engage. When it does, it's markedly louder than the other gears. Note: there's never a grinding noise suggestive of a syncro fail, just an increase in overall drivetrain noise. Using fifth requires understanding that the shifter path to fifth is very narrow, somewhat to the left of full right stop, and must be precisely managed. Sometimes it goes easily, other times, not so.

Also of note, I have to raise the reverse lockout collar as I seek to engage fifth. The reverse lights come on at this time; Tailgaters disappear.

2.) Locating reverse has become an unreliable proposition. Twice now I've been unable to place the shifter in reverse. Rowing through the gears, blipping the throttle do not help at these times. Nor has there ever been any grinding or alarming noises when using reverse.
As with my fifth gear attempts, it feels as though the transmission is not in alignment, that the linkage would deliver the shift the gears would allow it. The shifter linkage itself is intact.

I've read numerous threads about these problems and I am thinking that I have a worn motor mount. I will re-measure the lockout pin today, for safe measure.

I'd appreciate two things most of all, I think:

1.) advice as to what the problem(s) may be
2.) an ordered diagnostic path.

Thanks in advance.
