it has trouble going into first and third. second and forth are fine sometimes reverse will be 4th and i have not been into fifth yet i throw it in 1st and let off the clutch, start to pull of and it pops out of gear, but when i hold it in gear it stays in 1st. The car did have a sloppy clutch pedal and i could not get into gear while running. i threw in brass bushings and welded it fixed, problem solved. i also remove my shifter assembly to shorten the lever a lil while back way before the car ran. could the shifter assembly base be off and cause this issue?
