87 Sami 5spd.
All other gears workfine, only 3 and 4 do not. I pulled the shifter and can't manage 3 or 4 even with a screw driver. It's like something is frozen/locked up
Long story short, the rig sat for about a year but never had this trouble previously. Not sure what else to diagnose.
On a second note, what causes the truck to roll forward slightly after letting off clutch while in nuetral? TIA
