Trucks and SUVs have a variety of configurations. Look at yours before you order to verify your transmission and clearance. If you have skidplates or require a lower profile pan, check our stock capacity pan for the 6L80, 6L80E.

Camaro, Corvette, G8 and some Cadillacs also have the 6L80, 6L80E transmission. Please see PML's low profile pan as cars genenerally do not have the clearance for a larger, deep pan.

In many cases, you will need to drop the exhaust to install this pan. You would need to drop the exhaust to service the transmission with the stock pan as three bolts are not otherwise accessible. See installation images below that show the routing of the exhaust.

This pan can be modified for pan filling. Please call or email if you want this deep pan and need to fill through the pan.

Filter and Gasket Information

PML transmission pans work with stock filters, easily available from your favorite auto parts store. Because the pan is deeper than stock, filter supports are cast in. A deeper filter or extension is not needed since the transmission fluid is at the same level with a PML pan as with the stock pan. An image showing the inside of the pan and the filter supports is shown at left.

This transmission pan works with stock gaskets. PML designed this pan to accommodate the reuseable factory gasket. Please make sure the gasket is clean and free of any holes or nicks to avoid leaks.

Temperature Sensor Information

Three bosses are provided that can be machined for use with aftermarket sensors and gages. If you would like PML to machine a boss on this pan for a temperature sensor, the machining charge is $40 and this option must be ordered over the phone. The boss can accomodate 1/8 to 1/2 NPT. Let us know which location you prefer and what size to machine. The bosses can also be used as alternate drain plug locations.

Installations

2010 GMC 1500 Denali at Leon's Transmissions

Leon's Transmissions in Garden Grove, 714-534-3300, installed a black powder coated deep 6L80 pan on a 2010 GMC 1500 Denali. To get the pan installed, they loosened and dropped the exhaust. Leon's also installed a PML differential cover on the truck.

2011 Avalanche

Steve installed this pan on his 2011 Chevrolet Avalance LTZ 4WD 5.3 liter with a 6L80E transmission. The first image shows the stock pan and the exhaust crossover pipe. The center and right images show the PML pan installed. Steve loosened both exhaust flanges at the manifolds to allow the exhaust crossover pipe to drop down about a half an inch. This provided room for removing the stock pan and installing the PML pan. He captured 5.3 quarts of fluid and refilled with 8 quarts. Steve said "The fit and finish of your pans are incredible. I followed the instructions provided and reused the silicone gasket from the stock pan."

2007 Cadillac Escalade

Dave installed our 6L80 transmission pan on his 2007 Cadillac Escalade EXT AWD, 6.2 liter engine. He got the pan in the cast finish then painted it engine semi gloss black and sanded off the high points. For the installation, the exhaust had to be off the manifolds on both sides to get clearance for the pan. For the stock pan, only the right side needed to be off. He used the stock reusable gasket. He saw a temperature drop of 10F, no towing, no other modifications.
