Avalanche 1500 PML Transmission Pan Install

In the Chevy Avalanche Fan Club Forum, a 9/14/10 post described the installation of this PML transmission pan on a 1500 Avalanche. Other aftermarket pans required modifications to the exhaust, but the PML pan installation took this guy/gal under 4 hours. We have summarized his steps below and here's a link to the whole write-up.

• Got a Wix 58904 filter and it came with a gasket (early model filter)
• Removed skid plate
• Removed the engine mount bolts and jacked up the back of the transmission
• Put in the PML pan - a long handled ball-tip 6mm hex key recommended
• Refilled with 6 quarts of fluid (drained 4 out plus 2 more for the deeper pan)
