Late shift w/AC on
This is in an '85 Monte with the the L69/2004R combo.
When the AC is on the trans shifts late, about 3000 RPM or more. Without the AC on it's actually a little quick to shift. Does theTPS adjustment or function affect this? Any ideas or help is appreciated.
Thanks, Larry.

I don't see how the AC being on could affect the transmission operation (the 2004R is also a throttle valve controlled tranny). My only idea is that maybe its requiring a bit more throttle since the AC is on and its shifting later because of the increased throttle position?
