Bizarre shifting pattern 1984 Mercedes 300D automatic
Hello, The adjust of your t/v cable, not kickdown cable, and the operation of the vacuum controller at the rear of injection pump, and the modulator, is critical for this car to get a good shift.
Put you cable back on, adjust it so that when you have wide open throttle, the cable does not have any slack. Check the black vacuum line by the oil filter housing that goes to the modulator to see if it has vacuum. It should have about 10-15" vacuum and as you increase engine speed it should drop. If you get close to this, the trans should shift ok. If you cannot get vacuum at the modulator line, you need to ck vacuum supply, valve at rear of injection pump, hose routing, etc.
If the B2 piston failed, it would be difficult to move car or slip badly. Also, take into mind that at the bottom of your accelerator pedal stroke is a kickdown switch.
If you accomplish what I instructed, you will probably get a decent shift.
