Yesterday I went into 1st gear when I shouldn't have. Now 1st gear just slides out. Every other gear works fine? Did I screw up the syncros or something deeper in the transmission? Is my transmission screwed? Is it worth it to fix it or get it fixed? 1st gear has been acting up for the longest, but it holds after the 2nd or 3rd try. Sometimes I move up a little with 2nd then go to 1st.

How much would the estimate be for a syncro job w/labor?
