As a practical matter, since the truck has a C6 automatic, there is no
reason for the flywheel to come off. Given this tidbit of factual
information, odds favor it being on the right way. You should be able to
open an access cover on the bell housing to look at the flywheel and the
torque converter.

The wrong bolts could be a problem. I believe bolts are rated as Grade 3,
Grade 5, and Grade 8, where grade 3 is the type of bolt used in a
construction project, and grade 5 and grade 8 are automotive grades. You
stated Grade A, and that sounds alot like Grade 8 to me, and Grade 8 is the
proper bolt for this application. A Grade 5 is probably sufficient, but I
recall that Grade 8 has a higher tensile strength.

If the bolts you had were the type with a shoulder (un-threaded portion)
that was getting bottomed out and leaving the starter to wobble a bit, then
this could easily be causing a problem.

I would suggest you take a look at the flywheel from either the view of the
access panel or from the location that the starter normally lives in, but do
not pull the transmission down and take the bell housing off unless you know
for certain that the flywheel is backwards. It seems to me that if the
flywheel was backwards, the torque converter would not fit, so I doubt the
flywheel is your trouble.

Nick,
