B2200 / B2000 Vac Diagrams
 

I have added clickable links for some of the solenoid locations to show a blown up view with color coded lines.

Added the Idle up solenoid to the connection table. This solenoid is only equipt on trucks with an Automatic Transmission.

Transmission Modification page has been slightly changed. Added some pictures and reworded / added some information.

OK, so why does my truck with a M/T have both the Idle up solenoid and the Servo Diaphram?

RE: B2200 / B2000 Vac Diagrams
 

Beats me, that is what the factory manual says I've never seen one equipt on a M/T truck. It would make sense to have one though if you have power steering or A/C since these would put enough of a load on the engine to require adjusting the idle. If you have one of those thats probably the reason. Either way the diagrams have been added to the page.

OK, mine has both PS and A/C, but I agree I noticed it said for A/T in the Chilton manual that was left in the truck when I picked it up as well.

Weird thing is I just baught a truck that came with A/C and it has the idle up actuator but not the idle up solenoid..... weird.
