alright, so tonight i stop at a stop light, take off hit maybe 3,500rpms in 1st and then went to shift into 2nd and NOTHING!, so i shifted to third and continued on, went to shift into 4th and Nothing. So shifted to 5th and continued once more and used 1st, 3rd, and 5th, to make it back here. Reverse is also gone. So all my bottom gears are not available. The shifter will nto attempt to shift into them. Any ideas as to what it could be? any help would be great
