5 spd trans in older medium duty

[amunderdog]

What part holds the shifter in the hole?
My 5 spd is dropping out of 4th.
not popping out or jumping out.
If you drop power it will just fall out of the hole and then 9 times out of 12 drop back in. So you have to keep an eye on it if you are cruising to be sure it stays in the hole.

usually the gear lever on older boxes is held in by the cap on gearlever ball. The trans cover has two pins jutting into the shifter hole and the cap retains a spring and has two slots in it that comprise what I would call an inverted bulb socket arrangement.
A bulb socket has theese two slots and the bulb has the pins on its base. the cap has the slots and the gearbox top has the pins.
You push down and twist to remove and install it the same way.

Check your trans mount(s) ... classic symptoms of busted or torn rubber in a mount.

Good luck, just a thought-
