"You cannot tow with GM trucks in overdrive"

That is too general of a statement to be correct.  I own a 1999 Suburban.
Page 4-47 of my owners manual states "You should tow in OVERDRIVE (D).  You
may want to shift the transmission to THIRD (3) or, if necessary, a lower
gear selection if the transmission shifts too often (e.g., under heavy loads
and/or hilly conditions)."

I followed these guidelines with my 1997 Yukon (350) towing a 4700 lb
trailer many 1000's of miles with no problems.  67,000 miles when replaced
with the 1999 Suburban (454).  The Suburban has towed my 8000+ lb Airstream
many 1000's of miles without any problems.

IMHO the "don't tow in overdrive" is either another of those urban legends
or outdated information that applies only to older hardware.
