I've now got major shift problems after doing the ZF service kit and I feel sick in the guts.

The only thing that springs to mind is maybe I didn't seat the Mechatronic double square part properly but it seemed in when I installed. It only needed light pressure.

I don't know if I needed to push it in hard? Can you reinstall the Mechatronic unit with the bridge not in properly (or if it fell out during installation?)

Everything bolted up perfectly without any tight spots?

The other possible thought in my head is not enough fluid?

I feel so terrible that I may have borked up my car
