4l60e failure??!!
Just wanna say thanks to everyone and there will be more photos coming to maybe show what the culprit actually was.
letting go all of a sudden doesnt sound like clutches. wouldnt be a solonoid, you will manually have reverse and first. probably the input drum cracked and then the splines stripped in the drum. Did it originally shift hard enough to chirp the tires on the 1-2 shift at full throttle?
