This PML pan fits GM 4L60E, 4L65E, 4L70E, and 4L75E transmissions.
PML designed this pan as a heavy duty, extra capacity replacement for the GM deep pan that came with vehicles model year 1999 and newer. The step at the back of the pan matches the step at the rear of the stock pan to clear the exhaust pipe or frame cross member.
The stock GM shallow pan and the stock GM deep pan are shown in the picture below. Please use this image to help identify the pan currently on your vehicle.
Note there are two versions of the stock GM shallow pan. If your vehicle has a shallow pan, other than the few exceptions noted below, please see PML deep pan, part number 8650-1, or PML low profile pan, part number 9297.
With GM/Chevrolet vehicles, there are many configurations and options, so you should always check your vehicle to verify which transmission you have and look for clearance with exhaust and frame cross members for a larger pan before ordering.
Typically, this PML pan fits these vehicles:
Note to H3, Colorado 4WD, Canyon 4WD: Some 4WD Chevrolet Colorado and GMC Canyon as well as the Hummer H3 and H3T models have the 4L60E transmission. The front drive shaft on these vehicles is too close to the side of the transmission pan to allow the larger PML transmission pan to be installed.
Do not use this pan on a 700R4 or 4L60 transmission (vehicles about 1993 and older) due to filter incompatibility.
Stock GM Shallow Pan, Exhaust Under Pan, and Want a Deep Pan?
The following trucks and SUVs came with the stock GM shallow pan and may have an exhaust pipe close enough to the pan to prevent the installation of PML deep pan, part number 8650-1. This PML pan, part number 9427, can be used for these applications if you switch to the filter for the GM deep pan. See the section on filters for more information.
PML designed this pan to work with the 4L60E filters that fit the stock GM deep pan. Please see our Filter Guide for PML Part Number 9427.
Filter Supports, Temperature Sending Unit Locations and Drain Hole
This transmission pan has cast-in filter supports as shown in image. A filter extension is not needed.
The drain hole is on the driver's side, which is the top of the image.
Optionally, this pan can be machined for a temperature sending unit. The pan has bosses on the passenger's side and the driver's side that can be machined for aftermarket gages and sensors. PML has a machine shop on-site and can drill and tap to your specifications between 1/8 NPT and 1/2 NPT for a $45 machining charge.
Shift Cable Mounting 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.
