No ! Buy new parts and replace.
Not completely sure but it sounds like a detent pin to keep the shifter/trans in gear.
You will be driving along without the pin/spring and the truck will pop out of gear.
Third is important; do it right and fix it by cleaning up the trans, replacing worn or broken parts.
You will be better off in the long run.
