I am unable to shift my truck out of 2nd gear. I have tried doing it from under the truck an it is stuck. Any ideas why? How can I fix this?

 

Did you try rocking the truck while you unjamb the linkage? Make sure you are on level ground also.

I see in your other post that you say it has "fluid". I think you mean gear oil, because transmission fluid would be the wrong thing in that transmission.

 

Yes it did have gear oil....I have tried rocking it to no avail though. Im not sure what could be wrong
