Half the time I start out from stop lights, my shifter (I let it sit in 1st at lights/stop signs) will pop out of gear and go into neutral upon hitting the gas and releasing the clutch. Trying to put it back in normally requires a lot of griding and pushing. Same thing happens, just less often in 3rd and 5th, except normally they will just grind shifting into gear. Are my synchro's going?
