is it a factory pistol grip? how much slop is in the levers side to side? might need a rebuild,see brewers performance in ohio.ck the fit in all the levers and the rods. a sloppy shifter,and rods make a mess out of a trans to shift. then again it very well be the clutch NOT disengaging,from the mis adjustment,pilot bearing,ect. let out the clutch when stopped,push it in ,and try reverse,does it grind? maybe the input isnt stopping through the shifts?...then again the trans might be hurt....=call dan brewer.
