Re: [Amc-list] T-96 woes...

[Frank Swygert <farna@xxxxxxx>]

I had a similar problem when I first mated a T-96 to my 4.6L. The crank was from a 74 258 with auto trans. But mine wouldn't disengage! Turns out the pilot hole on the later engine isn't quite as deep as the one on the 63 196 the trans came from. I trimmed about 1/8" off the end of the input shaft with a cut-off wheel, tapered it with a grinder, and it worked great. 

I'm wondering if maybe the pilot hole in your crank is deep enough that the clutch will disengage, but shallow enough to put a bit of pressure on the end of the input shaft? I'd think there would be some signs of heat and/or rubbing on the end  if that's the case though. Just a thought...

Nahh, it's a HARD failure. The clutch shaft has a taper on the inside 
end, to hold the friction ring, making a cone. That cone was peened over 
from rotating jammed against the mainshaft! The friction ring (the brass 
thing with 5-sided teeth that does the early synchro engagement) had to 
be pried off.

I don't really understand the failure. The snapring was a bit loose, but 
come on, it wasn't THAT! loose! I'm not (that kind of) idiot!

Short of dropping the trans on it's nose, I don't understand how the 
snapring came off in the first place, or if THAT was a symptom of some 
weird assembly error or component problem. I assume I screwed up 
somewhere -- this trans operated, and fit just fine, before I started.
