What is the trans serial number, and the VIN?
In regard to the clutch grabbing high, it is hard to say, since they all grab relatively high. If it grabs high, and as soon as it grabs your foot is off the pedal, it is worn out. Recently had one like this, no slip, but it was worn down to the rivets.
If the snap-ring is bad you will get fore-aft movement of the shifter in 1st/2nd when goosing the throttle. Also the snap-ring can be broken and jammed in place and there is no symptom. Inspection is in order as Ed suggested.
The bottom line is this. If the snap-ring is not broken and loose, and you have no strange noises (gears rubbing inside the trans) you can inspect it and probably it is OK. I would not perform this repair unless either it is broken, or you are installing a clutch, since that requires the trans to come out and you will save $$ and not do the labor twice. Conversely if you do the repair, it is the time for a clutch.
Also FYI, recently I inquired about the parts needed for this repair, and they are all available. I have done quite a few
