We designed our 722.6/NAG1 pans to be better than the stock pan in many ways. Our pans are heavy duty, provide cooling fins, have a drain and locations for temperature sending units. Most importantly, our pans do not leak.
We heard many complaints about the stock pan leaking because of the retaining clip system. So unlike the stock pan, the PML pan does not use retaining clips. The gasket surface on the PML pan is thick and machined flat to prevent warping or leaking.
PML's design avoids the problems with the stock pan retaining clips. Bolts secure the pan to the transmission housing. PML pans include new bolts, washers and magnetic drain plug.
The flange on the transmission housing is a machined surface like the flange of the PML pan. So the flange of the PML pan and the flange of the transmission housing naturally make a leak-proof seal.
PML's improved flange can mate to the transmission housing with a thin bead of RTV. For those who like gaskets over RTV, PML designed and sells a cork and rubber gasket. It is compatible with all PML NAG1, 722.6 transmission pans and is $18.
PML cork and rubber gasket is $18. RTV can be used instead of gasket.
PML's gasket is not compatible with the stock pan. PML's pan is not compatible with the stock gasket.
