We have two Stage 6 4x4 Allison transmissions sitting here ready to ship or install.
Both are dyno tested, include the converter, and still come with warranty.
$5,000 each
Available:
2001–2002 Stage 6 4x4 Allison
Part # 128136200
2004.5–2005 Stage 6 4x4 Allison
Part # 128136202
Core required. Freight and core not included.
A good rebuildable core must come back.
These are priced to move. Great deal for someone needing a built Allison for their Duramax.
