For 2017 gas engine Canyon and Colorado, GM switches to an 8 speed transmission. See article in The Shop Magazine.
Benefits of PML Design
Finned to increase surface area for heat dissipation
Drain and magnetic drain plug
Thick walls and gasket flange
Heavy duty construction
Fill, Level Check and Drain on Stock Pan
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.
PML designed this transmission 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.

Ground Clearance, Stock Capacity Pan
This PML 6L50 pan may not provide enough ground clearance. Cars, such as Camaro and Corvette, would probably need a pan closer to the stock depth. Trucks with skid plates or modified trucks may also need a pan closer to stock depth.
Always check carefully for clearance.
We are considering a stock capacity pan or a pan about 1 quart over stock so there is more ground clearance. Such a pan would still include cooling fins and a drain plug. It would be 1 1/4 to 3/4 inch taller than stock with the fins. Please use the above sign up form if you are interested.
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 is slanted, meaning that the flange surface and the bottom of the pan are not parallel.
Our thanks to all those who have emailed us pictures of their installations:
Dennis installed this PML transmission pan on his 2017 Colorado. He reported that "
Installation was so easy, removed and replaced not even 1 hr" and that
"my trany is running about 10 to 15 degrees cooler now".
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.
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.
