PML designed this pan specifically for C5 Corvette owners who push their Corvettes to the limit and for owners who just want to take care of their Corvettes.

This pan allows for adding transmission fluid through the pan as required by 4L60 transmission in the C5 Corvette. The fill hole is on the driver's side. A plug is included with hardware.


This PML pan adds strength and aids in heat dissipation while maintaining ground clearance. It is a bolt-on replacement for the C5 Corvette stock pan.

This PML pan features extra capacity and will hold 3½ quarts more than the stock pan. Heavy duty sand cast aluminum construction adds strength to the transmission case. The fins on the bottom of the pan and the extra capacity keep the fluid cool. Cooler running temperatures through expanded oil capacity and raised fins will help reduce wear and tear on the transmission.

This pan is designed to fit 1997 to 2004 C5 Corvettes with the GM 4 speed automatic transmission. Please check your Corvette as configurations vary.

The drain hole and magnetic drain plug allow for easy transmission servicing to keep your Corvette running smoothly.

We have one of these pans on special: Special # 256

Filter Information

PML designed this pan to work with the stock filter for the C5 Corvette 4L60E transmission. The pan has cast-in filter supports so no filter extension is needed.

Please see our Filter Guide for PML Part Number 8650-3 for suggested part numbers and additional information.

The fill and drain holes are on the driver's side.

To avoid problems with filter extensions, PML cast filter supports into the bottom of the pan. See the section on filters.

Drilling and tapping for use with aftermarket sensors and gages is an option. This pan has three locations cast into the pan that can be machined, one on the driver's side and two on the passenger's side. These locations can accommodate from 1/8 NPT to 1/2 NPT. PML has a machine shop on site and can machine a pan to your location and thread specifications. There is a $45 machining charge.

Shift Cable Bracket

You may have to modify your shift cable mounting bracket to use this pan. If the trans pan mounting bolts hold the shift cable bracket on, please reference this article from Vette magazine for details.

Gasket Information

This Corvette transmission pan works with inexpensive stock gaskets, such as those made of cork or a rubber cork compound. The gasket flange is machined flat for a secure seal.
