How can I tell if My Allison 1000 has a DEEP pan or a Shallow pan?
The quick answer is to 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 while a SHALLOW pan is about 4-inches deep at the front of the pan while sloping to about 2.5-inches deep at the rear. Click Here to see photos and further explanation of the differences and how to identify a DEEP versus SHALLOW Allison 1000 transmission pan.
