    PML 6L90 pan benefits Click on image to view larger.

    PML design this transmission pan for vehicles that need to maintain ground clearance, such as Cadillac CTS-Vs, Camaros, Savanna vans, Express vans, and trucks with skid plates.

    Although this is a stock capacity pan, this PML pan is still deeper than stock. The extra depth comes from the thick walls and cooling fins.

    PML manufactures and sells an extra capacity GM 6L90 pan, PML part number 11036.

    2019 Silverado 3500HD 4WD 6.0L Single Rear Wheel Crew Cab Long Bed

    John noted that after 2 years, his stock pan already had some rust although the truck has never been on salt treated roads. He had no fitment or clearance issues. He did not raise the truck or drop the exhaust. He used a 1/4 inch wobble extension to access the pan bolts in line wiht the exhaust cross over pipe.

    Richard installed the PML stock capacity 6L90 pan on his 2500 in his garage using jack stands. His truck has slightly larger tires (285/65-18) and he did drop the exhaust to make removing the stock pan easier. He was pleased to report that the installation was straight forward and there were not any clearance issues.

    Stock Pans

    6L90 OEM stock pans and PML pan  Click on image to view larger.

    The 6L90 transmission has two stock pans that we know of. In this picture, the truck pan is on the left and the Cadillac CTS-V pan is in the middle, and the PML pan is on the right. The Cadillac pan and the PML pan have level check/fill holes.

    Level Check/Fill Hole

    Some cars and 2019 and newer trucks and SUVs have an OEM stock pan with an integrated standpipe level check on the bottom of the pan. This is usually because the vehicle does not have a dipstick in the engine compartment.

    This PML pan includes a level check in the same location as the standpipe that functions the same way and is at the same level.

    The level check on the PML pan is at the same location as on the stock pan with the level check.

    OEM stock pan is GM part number 24297102 (replaces GM number 24248164).

    Drain

    PML adds a drain hole and includes a magnetic drain plug for each pan. Easy draining simplifies transmission oil fluid changes. Drain is on the driver side of the pan.

    Optional Temperature Sensor Machining

    Optionally, PML can drill and tap a 1/8 NPT hole for a temperature sending unit. Verify the thread specifications for the sending unit before ordering.

    There are two possible locations. One location on the passenger side and one location on the driver side front corner.

    Select this in the shopping cart. PML includes a plug for the hole.

    What About a Transmission Pan Smaller Than the Stock Pan?

    Several folks called us about a pan that is LESS deep than stock for more ground clearance. We will NOT make such a pan. This would change how the filter would fit and work and we do not know how the transmission would perform with less fluid.
