I had the same problem in my 1990 300ZX non-turbo. The problem almost completely disappeared after I had the tranny/differential flushed. Shifting became much quieter, but I occasionally felt that grinding even when shifting perfectly. It usually happened during a high-rpm shift. The problem is now completely gone after replacement of two plastic bushings that sheath the bolt that links the shifter stick to the transmission control arm. They had worn off and fallen away. This caused there to be much extra "play" in the stick shift. Now the shifter is as tight as when it was new, and I no longer grind the gears. It was a $4 fix.
Reason is, your clutch is going out or tranny is about to be shot!
The synchro for those two gears is bad
there are 23 skating grinds
Your clutch cable needs to be replaced, it is probably broken from it's shield at the firewall.
The transmission is slipping/dying, take it to a certified mechanic..
3rd gear is bad,must put new gear in or replace transmission.
do I need to use my grinds first or I can use unuse grinds directly on my plants?
If it is automatic and it grinds, that means you must come to a complete stop before shifting into reverse, or your transmission is no good
When it grinds it teeth it means that it is happy
The homophone for "crushes or grinds with the teeth" is "gnashes."
The gizzard is the structure that grinds up the food.
A miller grinds wheat into flour.
