Im wondering what might be wrong with the manual transmission on my 1991 Ford f150...I was just driving along and i stopped then when I went to go again I didn't have first so I started in 2nd. Once I got going i down shifted turn and i didn't have 2nd. I am thinking its the selector rod, but I dont know it might be something else.

 

No first and second? 1-2 shifter fork.

 

So how much would it cost for that part and how hard is it to fix
