In Reply to: TSB only for '98 and earlier Subs? posted by grizzly on February 14, 01 at 05:34:38:
: The TSB indicates it only applies to '98 and earlier Subs. I am trying to figure out whether my '99 K2500 (built, I think, in March '99) is affected by the TSB.
: My GM dealer is unhelpful. Does anyone know if I need the TSB done on my Sub?

Had it done on my 99. Noticeable improvement.
