Help confirm the demise of my 4l60e
Stock tranny with about 86,000 miles. No problems whatsoever until yesterday. Pulled out of a parking lot and went to 3/4 throttle from a roll. Transmission shifted from 1st to 2nd and sounded as if someone hit the car with a sledge hammer (big bang!). Car went into limp mode. I have no reverse and you can hear a constant grinding noise when placed in neutral. No trouble lights on the dash. I have HPTuners but no DTC's are showing for the tranny which I think is a little odd. I have not had a chance to drop the pan but am I safe to assume that I will find pieces of the shell perhaps at the bottom? Again, I am assuming this suggests a complete rebuild. Any thoughts appreciated.

Yes, your transmission suffered a hard part failure. Probably the sunshell.
Typically you will not see debris from it in the pan. It's possible, but not usual.
Good luck.
