PML designed this extra capacity transmission pan for the GM TH350 (Turbo–Hydramatic 350) transmission.

Benefits:

• Extra capacity
• Drain hole and magnetic drain plug for easy fluid changes
• Finned for cooling
• Heavy duty sand cast aluminum construction
• Machined flat gasket sealing surface
• Can optionally be machined for a temperture sending unit

PML also makes a stock capacity version of this pan for vehicles that need more ground clearance. The stock capacity TH350 pan, PML part number 9589, has the external bosses that may interfere with the drive shaft on some vehicles.

Drain

The drain hole is on the passenger side of the PML transmission pan. A magnetic drain plug is included with the pan.

Check drive shaft on 4WD vehicles. The drain is on the passenger side. It may be difficult to access if the drive shaft is on the passenger side. The drain plug is a 3/8 NPT plug and 1 to 2 threads will still be visible outside the pan. This is about 0.050 to 0.100 inch. 

Filter

This PML pan works with the stock filter.

The filter bolts on to the valve body so no filter supports or extensions are needed.

Gasket

PML recommends a cork or cork composite gasket with this transmission pan. There are many available. For example, this cork/rubber composite gasket is Mahle Part Number 39348 and was purchased on Amazon.

Optional Temperature Sending Unit Machining

Optionally, you can drill and tap an 1/8 NPT hole for a temperature sending unit. This would be for an aftermarket temperature gage. 

There are two possible locations on this pan. There is a boss (thick area) on both the driver and the passenger sides of the pan for this.

Check your aftermarket gage to verify the thread specifications.
