I have a suzuki xl-7 2005 manual and is hard to change gear does this mean the clutch is gone or is there a easy fix

This is pretty easy to trouble shoot.
first off , assume it's a simple easy fix. it can be.
not 8 to 10 hours labor jerking the tranny and 4wd parts.etc.
hard to change gears can mean many things.
1: cant select. this is common, the shifter tip has 2 plastic parts
that cause the shifter to do 2 things, its loose as heck and
cause , SELECTION failure. that is ,you can not move the shifting
forks inside the tranny. is the reason, this is shifter failure.
Suzuki sells the parts, ,shown in link below.

2: hard to shift , #2 is , but you can not force any gears
reverse is the most difficult. and if you try hard enough
the transmission grinds. this is clutch failure. (1 of 2, ways)
3: if the clutch is failing, called DRAG. (not slip, no noise or chatter)
you can jackup the rear of car, at the axle place 2 jack stands
under said axle housing ends and now you can shift.
proving a bad clutch as it now shifts but in a clunky way.

ok, now we are in the Dragging bad clutch fails.
the first easy fix, is easy.
is called,a "bad clutch actuator"
on early cars this part is a cable (replace the cable)
on later cars the actuator is a MC/slave hydraulic pedal sys..
The cable clutch you do...the.. do the 1 inch test. see link.
on Hyd. do the 3/4 inch test. see the link.

this proves the clutch is good or bad , every time.
if the clutch lever fails to move the correct distance.
no clutch can work, fix the actuator first.
