Product Details

Fits 2001 & newer Silverado & Sierra 2500 HD & 3500 with Duramax & 8.1. Volume: 3.25 qts over stock. This PML pan fits 2001 to present Chevrolet & GMC full size trucks with the Allison 1000 5 & 6 speed automatic transmission. This transmission is found in the Silverado & Sierra 2500HD & 3500 with the Duramax diesel and 8.1 liter gas engines. This pan may also fit 2006 and 2007 H1 Hummers. Please check carefully for fit and interference on this vehicle. The pan has a boss that can be machined for a temperature sensor. Filters and Filter Supports: The transmission pan features filter supports that are an integral part of the floor. The filter supports are designed to be easy to alter. Out of the box the filter supports are set up to work with the shallow stock filter (OEM part number 29537514 or Allison part number 29537965). The supports can also be shortened to work with the deeper filter that Allison offers (part number 29537966) for this transmission. For the larger filter you'll need to cut the filter supports at the line designed into them for that purpose. After cutting the supports you'll have to make sure you use the deeper filter from then on as the stock filter would fall out of the valve body May 2012 Update: A customer has reported that the deeper filter part number 29537966 is now obsolete and the recommended replacement filter part number 29542824 does not work. We are looking into this. Please call or email if you need more information or have information. Information about filters for reference only. Installer should verify transmission, filter, and fitment based on the individual vehicle. PML Transmission Pan Features: Increased oil capacity for cooler temperatures Sand-cast aluminum with raised fins 3/16-inch thick wall construction to add strength to the transmission case 3/8-inch thick gasket flange will not bend when bolts are tightened Machined gasket surface for a secure seal Boss cast into pan can be machined for a temperature sensor Magnetic drain plug for easier, less messy maintenance Mounting hardware provided *Gasket and filter not included (use stock parts).
