Has anyone notice that the holes around the original equipment Allison spin on filter (part # 29539579) are in a position that you can see the holes when the filter is removed from the tranny - with the magnet still in place?
The Napa replacement part is # 7701. After pouring some ATF in the filter I placed the magnet on the new filter. The magnet clearly sits directly over the holes that are around the diameter of the replacement filter. I thought this was odd. Part # 7701 is printed on the side of the filter so I dont have a re-boxed situation.
I spun the new filter with the magent on, drove a few miles, no leaks, temp didn't raise out of the norm, seems OK.
