Sm465 issue

[tommy217xxx]

Hey everyone, my truck has an sm465 4 speed in it. Sometimes when I try to put the truck in reverse it seems like something is stuck. Meaning I can't get it to go into neutral or any other gear. When I release the clutch the truck stalls. When I try to let out the clutch and give it gas the truck doesn't move at all. I've noticed when I'm coming in to back her in, if I go right into neutral then into reverse theres no problem but if I go from first or second into reverse that's when it feels like somethings stuck. It almost feels like it's not releasing the gear and going into neutral. When the issue happens I try to move the gear shift to the neutral position and give it a side to side shake and nothin. Eventually the truck will go into gear but it can take a while.

Sorry for the long explanation because I'm not really sure how to describe the problem.
