Before You Order

• Deep pans only. For a shallow pan, see the 2001-2010 Shallow Pan Filter Kit or the 2011-2019 Shallow Pan Filter Kit.
• How to tell the pans apart: a DEEP pan is about 4.5 inches deep from front to rear. A SHALLOW pan is about 4 inches deep at the front and slopes to about 2.5 inches deep at the rear. Click here for photos and more detail.
• Filter lock: this kit is for use with our current MA Filter Lock (10690) and will not work with our previous MA Filter Lock (10474). The filter lock is not included.
• Not included: transmission fluid, the pan gasket and the drain plug are sold separately (see Related Parts).
• Filter color: Allison has temporarily used black paint instead of red on the spin on filter. Both colors are the same part.

Installation Tips

• Save the spin on filter magnet. A magnet sits between the spin on filter and the transmission. It often sticks to the old filter and gets thrown away by mistake. Clean it and reinstall it with the new filter. If yours is missing, see the Allison Spin On Filter Magnet.
• Install the deep internal filter with the filter lock to hold it in place.
• Check the fluid level with the dipstick using the procedure in your owner's manual, and use the fluid specification listed there for your truck.

Frequently Asked Questions

How can I tell if my Allison 1000 has a DEEP pan or a SHALLOW pan?
Look at the profile of your transmission pan. A DEEP pan is about 4.5 inches deep from the front to the rear of the pan. A SHALLOW pan is about 4 inches deep at the front and slopes to about 2.5 inches deep at the rear. Click here to see photos and a further explanation.

Will this work with my older MA Filter Lock?
No. This kit works with our current MA Filter Lock (10690), not the previous version (10474).

How often should I change the filters?
Merchant Automotive recommends replacing the internal filter every 75,000 to 100,000 miles and the external spin on filter every 12,000 miles. Check your owner's manual for GM's interval for your truck.
