Could be the linkage. If the wire link stretches over time, it will need periodic adjustment.
bad transmission..... expensive repair.
Gear up then
Yes , you need a gear box to make it work.
1999 ford explorer 4.0 manual transmission gear shifter wont fit on shaft
synchro plates went out
my 94 Toyota corolla will not go into any gears .
It is due to the momentum still in the blades.
The clutch is bad or out of adjustment.
Most likely a broken gear cluster
if you mean it wont go into gear and it grinds like a sob but other gears still work synchronizers. if you mean the shifter is loose an cant find the gear anymore - linkage. if it wont go into any gear sounds like a clutch problem
My first suspect would be the clutch. Have a competent mechanic take a look at it.
