I decided to change the Allison transmission filter on my Silverado and cut it open to see what was inside. Originally I was going to cut open a new one but ended up deciding that I didn't have the heart to destroy a new one of these. It's a good looking filter. I am guessing it was made by Champion Labs.
Here is the overview.
Here is the side view.
Here is a picture of the top.
Looking inside.
With the spring on top.
In the photos you will see some groves cut in the filtering media and a burn mark or two on the metal end caps. This was where my grinder went a little too deep. The can on this filter is very thick metal. I would guess about three times as thick as the can thickness of a high quality regular oil filter. Overall, this filter looks to be pretty high quality. (Not worth the $51 the Chevy dealer wants for it, but that's another story.)
