    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.

    Benefits:

    • 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)
    • Savana 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.

    Our thanks to those who have emailed us pictures of their installations.

    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 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

    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 6L90 transmission pan, filter supports  Inside of the PML 6L90 deep transmission pan, click on image to view larger

    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".

    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.

    PML designed this pan to work with 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 default, standard size. 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.

    Drain Plug and Bolts

    The 6L90 transmission has two stock pans that we know of. In these pictures, the truck pan is on the left and the Cadillac CTS-V pan is on the right. The Cadillac pan has a fill hole. This PML pan cannot be modified for pan filling.

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