PML designed this 6L90 transmission pan for 2007 to 2021 GM heavy duty gas engine trucks, SUVs and vans such as Chevy Silverado 2500HD and GMC Sierra 2500HD.
Volume: 2 1/2 to 3 quarts over stock
Dimensions: Click here for dimensions in a new tab or window. The truck stock pan is about 3 1/2 inches deep so the PML pan is about 3 inches deeper than the stock pan. Note that the 6L80 transmission pan is similar in shape but the 6L80 is shorter at 17 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)
PML designed this pan for 2007 and newer heavy duty Chevrolet and GM trucks and SUVs. 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
- Step in the back to clear exhaust
This pan fits the GM 6L90, 6L90E transmission, typically found on these vehicles:
- Silverado 2500 and 3500 HD with 6.0L or 6.6L gas engine, 2007 to 2021 (2020 and later models may have 10 speed)
- Sierra 2500 and 3500 HD with 6.0L or 6.6L gas engine, 2007 to 2021 (2020 and later models may have 10 speed)
- Suburban 2500, 6.0L, 2008 to 2013
- Tahoe 6.0L, not hybrid, 6.0L, some models starting in 2008 (2018 and later models may have 10 speed)
- Yukon HD, 6.0L, not hybrid, 6.0L, some models starting in 2008 (2018 and later models may have 10 speed)
- Express Van 2500 and 3500, 4.8L, 6.0L, and 6.6L Diesel, 2010 to 2019 (2018 and later models may have 8 or 10 speed)

Note: Trucks and SUVs have a variety of configurations. Look at yours before you order to verify your transmission and clearance. Vans especially should check for clearance.
Stock capacity 6L90 pan: Cadillac CTS-V and Camaro ZL1, some vans and trucks with skid plates may need a stock capacity pan, which offers more ground clearance than this deep pan. Please see our web page for PML Part Number 11088 if you are interested.
Installation: 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.
2017 Silverado 2500HD Denali
Richie's Truck & Auto in Hicksville, New York installed this PML pan on Scott's 2500HD. Scott let us know that the pan is custom power coated Illusion Cherry and the pan has dropped his temperatures by almost 35 degrees.
2015 Silverado 2500HD
Ray reported that removing the old pan was very easy and installing the PML pan was a "breeze". It slipped by the exhaust, close but right on. He loves the look and fit and being able to change the transmission fluid when needed.

2011 Chevrolet Silverado 2500 6.0
Jim installed this PML transmission pan on his 2011 Chevy Silverado 2500 6.0 4WD with an aftermarket exhaust y-pipe. He reported that the install was fairly straightforward, with very close clearance for the stock pan removal and PML pan install because of the y-pipe. He removed the shield, to the right of the pan and mounts onto the transmission itself, to install the PML pan. Removing this shield gave him more clearance to come in from the side and slide the pan in.
Jim noted that ground clearance with the PML pan is not affected at all. It is above the front cross member and above the torsion bars (from the side).
Our thanks to Jim for his pictures and feedback. These images show, from left to right: 2011 Silverado, view from passenger's side of PML pan installed, view from rear of truck showing clearance with PML pan installed
2010 Sierra 2500HD 6.0
Leon installed this PML pan on his 2010 GMC Sierra 2500HD L96. He liked that the pan is "solid".
2010 Silverado 2500HD 6.0
Jason installed this PML transmission pan on his 2010 Chevy Silverado 2500HD 6.0. This picture shows the PML pan installed and the stock pan sitting on the ground.
Jason reported temperature drops from 160–190 to 148–178 when towing a 6,700 pound trailer. He also sees lower temperatures during his daily drive. Read Jason's review of our pan here, in this PDF file.

2010 GMC Box Truck
Paul installed a PML 6L90 pan on his 2010 GMC G33503 Box Truck. He documented his installation with pictures in this PDF file: PML 6L90 Transmission Pan Installation
Our thanks to Paul for his great write-up. Paul used a mini vice grip to access bolts above the exhaust. Another suggestion for difficult to access bolts would be to cut down an allen wrench to fit.

Filter and Gasket Information
PML transmission pans work with stock filters, easily available from your favorite auto parts store.
Customers have told us that the stock GM filter is "GM Part No. 24236517" and the AC Delco box has part number "24236933".
This is a picture of the inside of the PML pan.
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.
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.
Machining for Temperature Sensors
Three bosses are provided that can be machined for use with aftermarket sensors and gages. The bosses can accommodate 1/8 NPT to 1/2 NPT. 1/8 NPT is the standard size. The bosses can also be used as alternate drain plug locations.
If you would like PML to drill and tap a boss, the machining charge is per hole.
Drain Plug and Bolts
This pan includes a magnetic drain plug and mounting bolts.
The drain is on the driver or left side. See picture.
PML 6L90 Transmission Pan and GM Stock Pans Compared

The PML pan is about 3 inches deeper than the stock truck pan.
