Thought I was buying a high quality filter brand. No Fram stuff. Micro size of the filter is obviously critical to the Allison transmission flow requirements.
Difficult to understand how a major filter manufacture had not done any engineering on the flow rate required on a replacement filter they are selling.
Seems to me they are opening themselves up to a class action law suit.
