I wish. I disconnected the linkage to check the control lever and it's the lever that is moving freely with little to no force required to move it. Or maybe I'm just a doof mean and it's supposed to do that. Once again transmissions are not my thing. It is a column shifter.
Sounds like it's inside the trans, but here's the thing.
There is a valve that moves in and out of the side of the valve body that controls fluid flows, and there is the part that moves that valve.
The part that moves the valve has the detents (the clicks when the linkage lever on the trans moves)
If that lever does not have any resistance to moving from position to position there is something missing.
The part that does that click click when you move the lever on the trans is called a rooster comb (because of what it looks like) and there is a ball and spring to keep it in position when in any given gear on the shift linkage.
On your trans there should be two levers (one above the other)
The top smaller one is whats called the throttle pressure linkage, and that part connects to your carb linkage and should move toward the back of the car as the throttle is opened.
The bigger lower lever under that is your shift lever.
I mention this just in case you might have them mixed up and connected the shifter linkage to the throttle pressure lever instead.
Lets see if this picture helps any, and maybe you can try to describe better what is happening.
