The GM 4L60E transmission has both deep and shallow oil pans, with the change from shallow to deep instituted in 1997. This was done to allow the transmission to hold more fluid and dissipate more heat. The deep pan is designed to work with the 4L60E filters that fit the stock GM deep pan, and has filter supports on the inside. The drain hole is on the driver's side. When ordering an oil filter, it is important to inspect the oil pan first, as some vehicles with the 4L60E transmission are not compatible with the larger PML transmission pan.

The 1997 GM 4L60E has a split style, with both deep and shallow oil pans
The GM 4L60E transmission is found in some 4WD Chevrolet Colorado and GMC Canyon models, as well as the Hummer H3 and H3T. The GM deep pan is designed as a heavy-duty, extra-capacity replacement for the GM shallow pan. The PML deep pan, part number 8650-1, can replace either style of the GM shallow pan. It is important to note that the front drive shaft on these vehicles may be too close to the side of the transmission pan to allow the installation of the larger PML transmission pan.
When ordering an oil filter, it is critical to determine whether your 4L60E has a deep or shallow oil pan. This is especially important for those rebuilding or replacing the oil filter in 1997 models, due to the split style. It is recommended to inspect your oil pan before ordering the oil filter to ensure you get the correct one.
The PML transmission pan is designed to work with the 4L60E filters that fit the stock GM deep pan. The PML pan has filter supports on the inside, and a filter extension is not needed. The drain hole is on the driver/left side. This pan can also be machined for a temperature sending unit, with a charge applied per hole. A plug for the hole is included.
Some vehicles may have the bell housing close to the transmission pan, requiring material to be removed from the leading edge of the PML pan for it to fit correctly. It is also important to check for clearance with the exhaust, drive shaft, and frame cross members before ordering.

The deep pan allows the transmission to hold more fluid and dissipate more heat
The GM 4L60E transmission can come with either a deep or shallow pan. The deep pan allows the transmission to hold more fluid and dissipate more heat. This is due to the increased depth of the pan, which allows for a greater volume of fluid to be stored.
The change from a shallow to a deep pan was instituted for all OEM 4L60E transmissions in early 1997. This means that some 1997 models will have a shallow pan, while others will have a deep pan. It is important to inspect the oil pan before ordering the oil filter, as the wrong filter may not fit correctly.
The deep pan is designed to work with the 4L60E filters that fit the stock GM deep pan. It has filter supports on the inside, and a filter extension is not needed. The drain hole is located on the driver's side.
Some vehicles with the 4L60E transmission, such as certain Chevrolet Colorado and GMC Canyon models, may not be compatible with the larger PML deep transmission pan due to clearance issues with the front drive shaft. It is important to check the compatibility of the pan with your vehicle before installation.
The PML deep transmission pan is designed as a heavy-duty, extra-capacity replacement for the GM and Chevy trucks and SUVs from 1999 onwards. It features thicker walls and a flange, which may require modifications to the cable mounting bracket for proper installation.

The deep and shallow pans have differently-sized filters
The GM 4L60E transmission is used in some 4WD Chevrolet Colorado and GMC Canyon models, as well as the Hummer H3 and H3T. The OEM 4L60E transmission was changed in early 1997 to include a deeper oil pan, allowing it to hold more fluid and dissipate more heat.
It is important to use the correct filter for the pan depth. A filter that is too short can fall out, and a filter that is too long will not fit. The gasket, however, can be the same for both deep and shallow pans.
In terms of functionality, shallow pans are perfect for achieving crispy textures and faster cooking times due to their even heat distribution. They are also ideal for single-layer recipes and consistent browning. On the other hand, deep pans excel at retaining moisture and accommodating layered dishes. They are available in various shapes, including round, square, and rectangular, catering to different baking needs.

The PML GM transmission pan is compatible with the 4L60E
The PML pan is a popular choice for those looking to upgrade their transmission pan. It has been installed on various vehicles, including the 2002-2009 Avalanche, 2003-2007 Hummer H2, 2000-2013 Silverado, 2000-2013 Sierra, and 2000-2005 Suburban 1500.
It is important to note that the PML pan will not fit all vehicles with the 4L60E transmission. Some 4WD Chevrolet Colorado and GMC Canyon models, as well as the Hummer H3 and H3T, have a front drive shaft that is too close to the side of the transmission pan, preventing the installation of the larger PML pan.
When installing the PML pan, it is recommended to use a cork or cork composite gasket. Additionally, if your vehicle has a bracket that attaches to the stock pan, you may need to modify the cable mounting bracket to accommodate the thicker walls and flange of the PML pan.
The PML pan offers several advantages over the stock pan, including increased fluid capacity, which allows for better heat dissipation, and filter supports on the inside, eliminating the need for a filter extension.

The PML pan is a heavy-duty, extra-capacity replacement for the GM shallow pan
The PML pan is made of sand-cast aluminum with raised fins and thick wall construction, adding strength to the transmission case. It features a machined gasket surface for a secure seat. This pan is designed for GM and Chevy trucks and SUVs from 1999 onwards. It is important to note that the PML pan cannot be used on a 700R4 or 4L60 transmission (vehicles about 1993 and older) due to filter incompatibility.
The PML pan has a part number of 8650-1 and can replace either style of the GM shallow pan. It is recommended to use a cork or cork composite gasket with this pan, and any brand of cork/cork composite gasket will suffice. When installing the PML pan, it is crucial to verify pan fitment and filter installation. The correct filter must be used to avoid transmission damage.
The PML pan offers a significant advantage in terms of capacity, providing extra space for transmission fluid, which aids in heat dissipation. This is achieved through the increased depth of the pan, allowing it to hold more fluid. The PML pan is an excellent choice for those seeking a heavy-duty and high-capacity transmission pan for their compatible GM and Chevy vehicles.

Frequently asked questions
The change in depth allowed the transmission to hold more fluid and dissipate more heat. The difference can be made up by changing the filter.
Check your truck, SUV, or van to see which stock pan you have. Look for clearance with the exhaust, driveshaft, and frame cross members.
PML transmission pans are heavy-duty, extra-capacity replacements for the GM and Chevy trucks and SUVs, 1999 and newer.
PML recommends a cork or cork composite gasket for use with GM 700R4, 4L60, 4L60E, 4L65E, 4L70E, and 4L75E transmission pans.
You must unbolt the transmission/transfer case from the cross member and then jack up the back of the transfer case against the floor of the truck. Then, disconnect the cable shift from the bracket and gently bend or pry the bracket.
