'01 GMC 2500 HD hard shifts
Been getting hard shifts from my truck lately. Intermittent issue, but may be getting more frequent. If it was in one of my Pontiacs with a TH400, I would say it was the vacuum modulator, but doubt seriously that this truck has one. Replaced by electronics? Tow/haul kicking in randomly maybe?
Fluid level fine, w/ bubbles on the stick when you check it running. Got about 120k on it. What have I got going on?

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
