Transmission shifts into gear hard

[subman60]

I was having trouble with my 82 240d not shifting correctly so I replaced most every rubber vacuum line on the car. Now it shifts at what I believe is at the right time. How ever when giving it about 1/2 pedal or more it makes neck snapping shifts. If conditions are right it will give me a 2nd gear scratch and in the rain it will fish tail when it shifts. I have not tried changing the filter and fluid yet, could that be the cause? I'm trying to get this car straitened out for my 17 year old new driver. Also the vcv actuator rod is supposed to have a plastic clip that connects it to another rod, mine broke and I'm using ziptyes to hold them together. Any idea of a better way to hold them or where to get the clip?

Thanks,
Mark
