Fits: 4L80E
An aftermarket overrun drum with sun gear for the 4L80E, covering L01-UP production, made in the USA. It uses the late-type sprag, part number 34650A, rather than the earlier-type sprag used on 4L80E overrun drums built before that running change.
This is an overrun drum with sun gear for the 4L80E, covering L01-UP production. It uses the late-type sprag, part number 34650A, rather than the earlier sprag design, so the drum and sprag should be matched to that later sprag when rebuilding.
