Welcome! Glad you joined.
You found an error in the factory documentation. Your truck obviously doesn't have EFI as that's a Carter YFA 1bbl.
The red rod is the kickdown linkage to the transmission. But if it isn't connected let's hope you have the C6 as a disconnected linkage to an AOD spells trouble.
So, does your shift quadrant say Drive/2/1? Or does it have an O with a D inside it? The former is a C6 and the latter is an AOD.
I'm betting it is a C6 or you'd have all sorts of problems. And a disconnected kickdown linkage on a C6 simply means that when you floor the throttle the tranny doesn't automatically kick down a gear. I've run them that way and realized that if I wanted to downshift to pass I needed to pull the lever down into 2nd.
Last, where's home? I ask because we have a map (Bullnose Forum/Member's Map in the menu) and we could put you on it if we had a city/state combo or a zip code.
