The GM 6L50 transmission is found on 2015 and newer Canyon and Colorado and models of Cadillac, Camaro Caprice, and Corvette.
Always check your vehicle to verify transmission and clearance. Configurations vary. Cars may need a PML stock capacity 6L50 pan.
See Installations below for examples.
For 2017 and newer gas engine Canyon and Colorado, GM switched to an 8 speed transmission. See PML deep 8L90 transmission pan (in development), part number 11140.
Finished prototype phase April 2018. Made small design updates May 2018 to add a little more clearance for the exhaust on gas engine trucks and make the pan 5 inches deep.
Benefits of PML Design
Fill and Level Check
On the stock pan, we've heard that the fill is actually a hole in the main casing, on the passenger side, that is plugged with a rubber plug (no dip stick or fill tube).
We have heard that the level is checked by removing a bolt that looks like a drain at the rear of the pan while the transmission is operating at temperature. If no overflow occurs, the transmission needs fluid. Check your owners manual for the procedure for your vehicle.
The PML level check hole is at the same location relative to the transmission as on the stock pan.

Stock pan does not have a drain plug, so changing the transmission fluid and filter is a messy procedure.
PML pan has a drain hole on the driver side. A magnetic drain plug is included with the pan.

Filter Supports, Inside of PML Pan
This PML transmission pan works with the stock filter.
PML designed this pan with filter supports. These hold the filter at the same location as the stock pan so no filter extension is needed.
The fluid level and pick-up remain the same with a PML pan as with the stock pan.

PML 6L50 transmission pan works with stock gaskets.
Ground Clearance, Stock Capacity Pan
Cars, such as Camaros and Cadillacs, would probably need a pan closer to the stock depth. A modified truck may also need a pan closer to stock depth.
Always check carefully for clearance.
Depending on demand, PML is planning a stock capacity pan that would be about 3/4 inch taller than stock. See PML stock capacity 6L50 pan, part number 11149.
PML Transmission Pan Compared to Stock
These images show this PML transmission pan compared to the stock pan.
There are two stock pans for the GM 6L50 transmission. One has heights of 3.3 inches at the front of the pan and 2.5 at the rear and the bottom flat part is 10.25 inches. The other pan is 3.1 inches in height and the bottom flat part is about 9 inches.

2016 Canyon 2.8 Diesel 4x4
Jeff's Canyon has a Zone 5.5 suspension lift and has ample ground clearance. He reported that installation took about an hour. He noticed a 10 to 15 degree difference in transmission temperature after installing this PML pan.

Nick installed this transmission pan on his 2016 Colorado 2.8L Duramax Diesel 2WD truck. His truck has a 2 inch leveling kit. He reported that after installing the pan he drove to Idaho and his fluid temperatures were 20 degrees lower than on his last trip.
He checked clearances and reported that the PML pan does not hang down below front cross member.

2016 Colorado 3.6 Gas
Gas engine trucks have the exhaust cross over pipe under the transmission pan and the level check plug does not allow the stock pan to slide off. So Robert had to loosen and lower the pipe for more space so he could remove the stock pan and get the PML pan installed. After that, the installation went smoothly.
After installing the PML pan, Robert saw a fluid temperature reduction of 10 to 15 degrees when returning to highway speeds after stop and go traffic.

2010 Camaro 3.6
Monty installed this transmission pan on his 2010 Camaro Limited Edition LLT 3.6 V6.
Monty's Camaro has been modified with oversized tires and an aftermarket dual exhaust and muffler, so his Camaro is raised about 1 inch. This deep pan is not recommended for a stock Camaro.
The extra clearance on this Camaro provides enough space for this deep sump PML pan. Monty drained 7 quarts and added 9 1/2 quarts of fluid. He realized a 15-20 degree operating temperature drop after installation.
