First of all, this all started after driving through a flooded street about 6-8 inches deep (didn't have a choice). When I'm at a stand still and I proceed to put it in 1st gear, it doesn't want to go in. I don't force it in.....I put it in neutral, wiggle it, press the clutch and try it again and it'll go in with a grind. If I'm coming to a stop at a red light still rolling slowly, it'll go in without any problems. What do you guys think is happening?
