What a pitiful excuse for a kickdown band

Wow that was a great deal. Cast bands are becoming very hard to find anymore

Chrysler has put millions of flex bands in the 904 and the 727 and continues to do so today with the A518 - A618 series of transmissions and the A500 -A500SE transmissions. Customers building HP 727 transmissions would use the high energy band from the A518 - A618.
As others have said, they've put hundreds of flex bands in rebuilds with few if any issues, and I've sold thousands over the years I worked in the industry. Yes, once and a while you'd get a bad one, but that happens with anything man-made.
The castings to the best of my knowledge are not being cast by anyone. My experience, both as a seller and a buyer, if you didn't have a REBUILDABLE cast core, I wouldn't sell them, nor could they be purchased from our suppliers.
