Part Number 11150
PML started design work for a new deep transmission pan for the GM 6L50. A computer generated image is shown.
Our design increases capacity by about 2 quarts. The pan would be about 5 1/2 inches deep, total. (Actual part will NOT be blue.)
Availability and Pricing: We plan to have prototype parts available late this Fall.
We will not have any pricing until we have made some parts.
The GM 6L50 transmission is found on models of Cadillac, Camaro and Caprice, and 2015 and newer Canyon and Colorado. The 6L50 pan has 17 bolts and is smaller than the 6L80 or 6L90 pans. The stock pan measures about 17 x 11 x 3 inches.
For 2017 Canyon and Colorado, GM is switching to an 8 speed transmission for some models. See article in The Shop Magazine. Customer have reported to us that the 2017 diesel engine models will still use the 6L50.
Benefits of PML Design
- Extra capacity
- 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).
Level is checked with 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.
Stock pan does not have a drain plug, so changing the transmission fluid and filter is a messy procedure.
