Wondering about my 3rd gear syncs. At times it seems to grind going into 3rd only. Typically only when speed shifting or sometimes downshifting. At times I can just throw the car out of 2nd an it will automatically go into 3rd. I was thinking it could be bc I just readjusted my driver seat or my son drove and moved my seat and not pushing clutch all the way? It is not a consistent problem and only started a week or so ago after moving the seat a little?
