Torque specs for flexplate bolts on 02 GMC 2500HD?

Reinstalling the transmission and a new flexplate on an 02 HD with a 4L80E. Anyone know how tight the flexplate bolts have to be (flexplate to engine and flexplate to TC)? Thanks

1st pass 15ft lbs, 2nd pass 37 ft lbs, and final pass 74 ft lbs for the flywheel to crank, 44 ft lbs for the torque con bolts.

However if it's an aftermarket converter I don't recommend that much TQ. The ears of aftermarket converters seem to strip very easily. I just loc-tite them and "snug" them up. JMO.
