85 300D Automatic Transmission Linkage adjustments

The Service CD has no Guidance on the Automatic Transmission! Only the Haynes manual does. Does anyone have any troubleshooting Tables?
!!There is a flat spot in the gas pedal when I first push on it. The car hesitates and doesn't move too fast and then suddenly it comes to life after the first 1/4 to 1/3 pedal stroke. The problem is less significant as the engine warms up.
I thought the problem was in the fuel system/fuel system linkage at first because of the Temperature Dependency and the temp sensor on the Fuel Pump. Yesterday when I was fooling around with the throttle linkage, I started to suspect the Transmission shift linkage.
Do you know that wire with a rubber jacket and 12mm plastic nut that runs to the throttle assembly on top of the Valve Cover from the transmission? If I turn on the nut to make the wire taut will that reduce the power lag?

Carrameow,

I'm not positive about the '85 model, but the '81 has an arrangement on top of the valve cover that uses vacuum switches to simulate the vacuum signal from a gas engine that is the shift signal for the automatic transmission. Since you just put the car back together, I expect that you have a broken vacuum connector or some such problem.

Best of luck,
