This is what’s wrong with my 1998 Honda CR-V manual transmission.
When it’s off, the gear stick works normally. However, when I start the car, the gear stick gets stuck and won’t move to change gears. It happened before a couple times and if I warmed the car up for about 10 minutes it worked normally again, and normally the next time I drove it. However, this morning, the gear shift would not work even after warming it up, except when the car was turned off.
