On a gear start, except for Park position the detents are built into the valve body and manual control valve assy. As the valve slides in or out there are a pair of spring loaded rounded end plungers that push into corresponding circular grooves along the length of the manual valve. When the car is moving and there is hydraulic pressure the plungers are fed an additional varying pressure related to speed from the hydraulic system to supplement the springs so as to increase the strength of the detent and lessen the chance of being accidentally knocked out of gear.
If you have disconnected the rod from the outside lever on the drivers side and tried to move the lever you will feel the detents at their lightest. If all is working you will feel and hear a distinct click at each position except park. The end of the outer lever should not move more than a tiny amount so anything more than maybe a sixteenth inch or so when in detent and something is wrong either with the detent plungers or the tightness of something on the shaft. One poster found one of the plungers and spring laying on the pan because hydraulic pressure had blown the plug out the end of the plunger bore.
The only spline involved is at the end of the steering column. There is a stationary metal plate assy similar to this photo of a regular Ultra setup. When you pull the lever toward you there is another lever with a pin on the end which moves downward on the splines. The large arrow points to the moving piece. The pin fits into positions on the stationary metal plate. This is the safety assy which releases the operator lever so you cannot accidentally bump the lever and do damage. The assy is to make sure the lever is pulled toward the driver to move the pin away from the plate and get in or out of Park or Reverse.
Also check the bellcrank assy below the metal plate sector assy where the vertical rod changes to horizontal. In some models it is carried by rubber bushings and brackets. Rubber deteriorates and the bolts holding the bracket can loosen. Either introduces some play so movement from the operator lever might not be fully transferred to the rod and trans outside lever.
