PML designed this 6L90 transmission pan for 2007 to 2021 3/4 ton GM heavy duty gas engine trucks, SUVs and vans such as Chevy Silverado 2500HD and GMC Sierra 2500HD.
- 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
The truck stock pan is about 3 1/2 inches deep so the PML pan is about 3 inches deeper than the stock pan.
For a heavy duty pan closer to stock depth, see PML 6L90 Stock Capacity Transmission Pan.
The 6L80 transmission pan is similar in shape but the 6L80 is shorter at 17 1/2 inches.
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 2022 (2020 and later models may have Allison 10 speed)
- Sierra 2500 and 3500 HD with 6.0L or 6.6L gas engine, 2007 to 2022 (2020 and later models may have Allison 10 speed)
- Suburban 2500, 6.0L, 2008 to 2013
- Express Van 2500 and 3500, 4.8L, 6.0L, and 6.6L Diesel, 2010 to 2022 (2018 and later models may have 8 or 10 speed)
- Savana Van 2500 and 3500, 4.8L, 6.0L, and 6.6L Diesel, 2010 to 2022 (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. Some Tahoe and Yukon HD 6.0L, not hybrid, may also have this transmission but most have 6L80 or a 10 speed 10L80.
Stock capacity 6L90 pan with Level Check Hole: Cadillac CTS-V and Camaro ZL1, some vans and trucks with skid plates may need a pan closer to stock depth. See PML 6L90 stock capacity pan, which offers more ground clearance than this deep pan: PML Stock Capacity 6L90 Transmission Pan With Level Check.
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.

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 Silverado 2500HD 6.0L
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

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.

Frank installed this PML transmission pan on his 2012 Suburban 2500. He included a few notes on the installation process:
- The frame has cutouts for the rear bolts
- Put on gasket first
- Rail near solenoids
- Wiggle pan carefully at an angle over the solenoids
- Did not drop exhaust

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 designed this transmission pan to work with OEM/stock filters and gaskets.
The OEM gasket from the factory can be reused if clean and free of any holes or nicks which can cause leaks.
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.
Level Check Hole
Some cars and 2019 and newer trucks, have a stock pan with the level check on the pan. These vehicles may not have a dipstick. This PML pan is compatible with those applications. If your vehicle does not need a level check on the pan, then simply plug the hole (plug supplied) and forget about it.
Originally, PML did not make this pan with a level check hole as trucks and SUVs all had dipsticks until around 2019.
PML updated the pan to include the level check hole and plug.

Machining for Temperature Sensors
Three bosses are provided that can be machined for use with aftermarket sensors and gages. 1/8 NPT is the default, standard size. Contact PML for other sizes other than 1/8 NPT. The bosses can also be used as alternate drain plug locations.
If you would like PML to drill and tap a boss, select the option in the shopping cart or call to order. A plug for the hole is included.
The drain is on the driver or left side. A magnetic drain plug comes with the pan.
Included in Package
This pan ships with a magnetic drain plug, level check/fill hole plug, and mounting bolts.
PML 6L90 Transmission Pans and GM Stock Pans Compared
The 6L90 transmission has two stock pans that we know of. In this picture:
- OEM part number 24226851 is on the left. It does not have a level check tube and is commonly found on 2007 to 2019 trucks, SUVs, and vans. Some newer vehicles also have this pan.
- OEM part number 24248164 is on the right. It has a level check tube. OEM part number 24248164 supersedes several other parts numbers for the same pan. It is commonly found on cars and some 2019 and newer trucks, SUVs and vans.
