New to the group. Today I was pulling off from a stop sign roads were wet. While pulling off tires started to spin (break traction) and then it was if the transmission just stop pulling. Reverse, and drive just roll as if in neutral. And it’s making a loud knocking or noise that sounds like it’s coming from the back of the engine front of the transmission. FYI air suspension has been converted! Any leads on where I should start my trouble shooting?
