Pay particular attention to cleaning and polishing the end of the shift tube where the shift levers are located. The levers need to be absolutely free to independently rotate on the tube. My tube was corroded and rusted so the top lever was stuck solid.

When the tongue selects one of the levers to rotate it to shift into a gear, the other lever must be completely free so it stays in position held only by the detents in the trans. If one of them (usually the upper 2-3 lever since it gets any water or dirt collecting on the tube and no place for lube) is rusted or corroded to the tube it will want to move too and cause the operator lever to bind up so badly continued force trying to shift will break the potmetal at the operator end.

As far as function, the Ultra lever and tube is very similar except that the shift lever is a single piece and fastened to the rod. Pulling back on the operator lever drops it down so a pin on the lever can clear the park and reverse locking detents in the pie shaped sector piece.

Here is a 47 setup and I believe except for the shape of the shift levers the 51-4 standard trans have the identical tube, rod and tongue arrangement.
