Volume: 2 quarts over stock

Dimensions: Click here for dimensions in a new tab or window. The 6L90 pan is similar in shape but is longer at 18 1/2 inches.

Number of Bolts: 18 (there are 20 holes, 2 holes locate the gasket and 18 holes for bolts to hold the pan to the transmission case)

Description and Applications

This extra capacity heavy duty transmission oil pan fits the GM 6 speed hydramatic 6L80, 6L80E transmissions. PML designed this pan for 2006 and newer Chevrolet and GM trucks and SUVs, such as Silverado, Sierra, and Avalanche.

This pan features:

Extra capacity
Fins and aluminum construction to dissipate heat from transmission fluid
Drain plug for easier maintenance
Thick walls to add strength to the transmission housing
Thick gasket flange, machined flat, for a leak-free seal

This pan fits the GM 6L80, 6L80E transmission, typically found on these vehicles:

Avalanche 1500, 2009 and newer
Escalade, 2007 and newer, V8 6.2L
Hummer H2, 2008 to 2009, V8 6.2L
Sierra 1500, 2009 and newer, V8 5.3L or V8 6.0L
Sierra Denali, 2007 and newer, V8 6.2L
Silverado 1500, 2009 and newer, V8 5.3L or V8 6.0L
Suburban 1500, 2009 and newer V8 5.3L or V8 6.0L (includes HD)
Tahoe, 2009 and newer, V8 5.3L or V8 6.0L
Yukon, 2009 and newer, V8 5.3L
Yukon Denali, 2007 and newer, V8 6.2L
Yukon XL 1500, 2009 and newer V8 5.3L or V8 6.0L

Trucks and SUVs have a variety of configurations. Look at yours before you order to verify your transmission and clearance. If you have skid plates 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 generally do not have the clearance for a larger, deep pan. It is PMLpart number 11087.

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

Click on image to view larger.

This image shows the inside of the PML pan.

PML transmission pans work with stock filters, easily available from your favorite auto parts store.

Because the pan is deeper than stock, the pan has filter supports 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.

The stock GM filter is "GM Part No. 24236517" and the AC Delco box has part number "24236933".

This image shows a 6L80E transmission, stock filter and stock reusable gasket.

This transmission pan works with stock gaskets.

PML designed this pan to accommodate the reusable 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 accommodate 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.

Drain Plug and Bolts

This pan includes a magnetic drain plug and mounting bolts.

The drain is on the driver's side.

Installations

PML Transmission Pan on 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.

RV Magazine Installs PML Transmission Pan and Temperatures Drop

RV Magazine January/February 2014 Tech & How-To section goes through the installation and testing of a deep PML 6L80 transmission pan on a 2012 Chevrolet Silverado. Here's a quote from the end of the article:

"Our testing route took us on a 26-mile loop, up and down 6-percent grades the whole way. On the final hill where we noted our temperatures it takes about 10 minutes to reach the summit at 55mph. Before the PML pan, our transmission temperature measured 159 degrees at the base of the hill and 210 degrees at the top. Once over the top and coasting down the backside, the temperature continued to rise, hitting 218 degrees before starting to cool down five or six minutes later. With the PML pan, our temperature was 160 degrees at the base and 192 degrees at the summit. That’s a pretty decent difference, but what was really fun was how quickly it cooled back down. Almost immediately after cresting the hill, the temp began to drop, more than 5 degrees in about a minute. Impressive."

PML Transmission Pan on 2011 Avalanche

Steve installed this pan on his 2011 Chevrolet Avalanche 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."

PML Transmission Pan on 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.

PML Transmission Pan on a 2014 Silverado 1500 V6

Ian Macdonald at Dark Side Oils installed this PML pan on his 2014 Silverado 1500 with the V6 engine. He had these comments about the installation and temperature readings:

" Just wanted you to know that I installed my new 11025 trans pan on my 2014 Silverado 2wd with 4.3 V6 and there are no interference issues whatsoever. There is plenty of clearance between the tranny and the exhaust crossover making this install a breeze. BTW as other reviews have stated this pan is awesome, well made, very solid and looks great!! "

" I was able to do a before and after driving comparison as well. As it happened I had to drive 180kms one way and had the cruise set at 115 kph (approx. 70 mph) with outside temp (as displayed on my DIC) of 9 deg C for the whole trip. Terrain was southern Ontario were things are fairly flat. Trans fluid temp was 88 deg C and steady for the last hour of the trip. I then changed the pan and refilled with 7.6 qts of AMSOIL Trans Fluid. My return trip the next day on the same route and distance at the same 115 kph set on the cruise control and ambient temp was now 12 deg C. The tranny ran at a steady 85 deg C for the last hour of this return trip. In both cases there were no stops. Considering the ambient temp was 3 deg warmer and the fluid was 3 deg cooler the net differential was 6 deg C (10.8 deg F). Not bad at all I’d say!!! "

About the Similar GM 6L50 Transmission

The transmisison pan for the GM 6L50 transmission found on models of Cadillac, Camaro and Caprice, has 17 bolts and is smaller than the 6L80 or 6L90 pans (17 x 11 x 3 inches).
