2007 3.0 si.
Heard a pop when taking off and engine just revs in any gear. Selector moves lever on tranny about 3/4" - 1". Does that that amount sound correct?

No codes for tranny stored in computer. No lights on dash.

I am guessing the plastic valve selector is broken in tranny. https://blog.bavauto.com/16677/bmw-a...2-e83-ga6l45r/

Anyone have any other suggestions? No issues before this.was running great. Does selector movement sounds within normal?
