Don,
When I installed my first Cad500, totally rebuilt, I used the hd converter
I'd installed on the 455 some years before. After 4000 miles, it cracked
around one of the mounting lugs -- nothing to do with the Cad. I then had
a 47 years in business local rebuilder do me a torque converter -- a
"school bus" version with all the bells & whistles, according to them.
After 2000 miles, I found the crankshaft had 0.120" end play (up from
about 0.004"). There WAS adequate end play for the the TC when I installed
it. After having the crank rebuilt, I reinstalled it with 0.004" end play.
365 miles later it had 0.060" end play! What th'...???
In frustration, I rebuilt and installed a different 500 and a NOS Manny
Tranny specially built for me. For a torque converter I contacted Midwest
Converters, as others have suggested. IIRC, they proposed a 1200 rpm stall
speed. I haven't checked it, but it doesn't seem that high to me. I've
got close to 20,000 miles on it now with no problems.
As for the locally built TC, I talked to the owner of the company a couple
of months ago. We're agreed that I'll take to him for teardown. I'm
reasonably confident that he'll give me an honest appraisal of whether it
somehow caused my.
