86 560SEL

Thanks for your help Sleepwalker, I want to look at everything before I put it back together but the transmission part stumps me. However from reading some of your posts some things can be checked without expensive equipment.
Here is the problem: P to R about 4 second delay, starts in second (normal), 3rd slips (only if driving smoothly, if I stump the gas they all switch fine), and I am all the way to 4th (which doesn't slip) between 25 and 30mph, and lastly the car slows down while going down hill and I can feel the trans and the engine almost fighting each other ( I can see the tach go down 500rpm, car slows down then lets go rpm back up over and over). You had mention some bands and other things inside trans but before I go that far I want to check the simple things. I have a B switch on my trans.
From what I gather from previous posts I need to check the kickdown solenoid, vacuum line, trans fluid. Does anyone have a picture of a 86 560SEL with B switch transmission just so I know where these parts are located?

Thanks
