DETAILSHave a low miles transfer case out of a 2009 Silverado 2500HD. This was a gas 6.0L truck with the 6L80E, I believe it will fit a duramax 6.6L truck with the Allison, but not certain. Should fit all 2007.5 Silverado / Sierra 2500 HD gas trucks. This is a MP1226XHD without the shift motor. Will work on getting some pictures up later today.
