Have my car in the shop today. Last night after downshifting to make a right at an intersection. After I turned I tried to back into 2nd but the shifted wouldn't stay in gear. Now I can move the shifted around like its not connected to anything. We had the car up on the lift and all the cables are connected. Anybody have any ideas?

 

bent fork?

 

Broken shift linkage

 

Can't edit on phone, you said cables are all connected? I'd agree with bent fork as well
