it's been down so long i don't remember if it was there before. i just installed my orion and hardtop(hardtop may be the reason i can hear the whining now) and there is a high pitch whining at high speeds. i can hear it in fourth and fifth gears and the pitch changes with speed, not with the shifting of gears. it sounds like it could be a bearing, but my trans was just rebuilt and the orion came with all new bearings. could this be breakin noise? also, i don't have a shifter boot, so it would not be as strong if i had one. any ideas?????
