Are you talking about the transmission nut where it tells you to punch it with a chisel to lock it? Is that the lock nut you're referring to? These types of nuts are similar to most axles nuts found on the ends of CV shafts. The thin bit of metal at the top of the nut that you chisel in keeps it from loosening. All you have to do is take a small flat head screw driver and lightly hammer that thin bit of metal back out. Or you can just take an impact gun and unscrew that nut without hammering out the locking bit, I've done that before too. Some people reuse these nuts but I just bought a new one to be safe.

StipWRD Thanks. I didn't know if I could take the nut off without removing the clip. I guess I can put the clip back in when I reinstall the nut. With it in my hand I can figure it out how to install it.

It's not really a clip, its a thin piece of metal on the top of the nut that gets hit with a screw driver and forced into a cavity in the threads. Here's an example of this type of nut on an axle shaft:

Same principle on the transmission nut. Good luck

STI NOW, I get it!!! You are the Man! Communication is SOOO important. The first thing I asked myself when I saw the directions is What size socket and what is that clip? I kind of see things in Three Dimensions.
