Vehicle configurations vary so always check your configuration and clearance before ordering. Some models may require modification of the heat shield.
Earlier model year vehicles will need a pan without a slant to avoid interference with transmission internals. See this extra capacity PML pan for GM 4L80E/4L85E transmissions on early model trucks.
For Hummer H1: please read these additional instruction tips: PML Part Number 9437 on a Hummer H1 Installation (a new window or tab will open with the PDF file).
Installation Notes:
- Because of the frame cross member, many vehicles will need to loosen the transmission mounts and jack up the transmission to remove the stock pan and install the PML pan.
- Some vehicles may need to modify or remove the heat shield.
- Depending on clearance available on the vehicle, accessing the mounting bolts maybe difficult. PML provides allen head bolts and PML pan walls are thicker and closer to the bolt holes than the stock pan.
