5. The reversing gear shift lever on my A-4 completely slipped off the cross shaft (I think it is called cross shaft). Could you please tell me how I can reattach it, and why it slipped off in the first place? The cross shaft appears to have an open slot on each side about the size of a quarter. But I don't find any thing on the shifting lever that is designed to go into it. Not sure what is the purpose of the slots.

The slots on the cross shaft are to accommodate Woodruff keys (1/8" X 1/2"), which are intended to keep the shifting lever from rotating on the shaft. Your keys must have fallen out when your lever came off of the shaft.

If the hole in your lever itself is somewhat enlarged, you may be better off to purchase one of our new shifting levers. They are made with a compression hub that makes them quite a bit more secure than the original levers.

If you order a new lever, ask our sales representative (Ken) at 610-421-4436 to have our warehouse tape a new Woodruff key to its handle; otherwise, the keys are available at most auto parts stores. - Updated: August 3, 2010
