Who said there was an obsession with a T400? And if there was, wouldn't that state the obvious? I'm not here to debate. 904/727/T400/4L80 Use what makes YOU happy, what YOU pay for, and what gets YOUR job done.
On the other hand, I do have a obsession with my FORD 9".. if anyone would you care to join me? an 8 3/4 to a 9"? Dana 60 to a 9"? I'll take the weight savings from the 9" to make up for the use of a junk T400.
