I did not know
We have a 2007 Chevy HD 2500 truck that we bought new. We pulled and lived in a fiver for three years.
I had the tranny serviced every 25,000 miles while towing, and since, every 50,000 not towing.
The truck has 226,000 miles on it. It started showing signs of leakage a few months back, and I assumed it was the front seal. I added fluid as needed.
I decided to take it in to a tranny shop. They tell me that even though it (allison) has a spin on filter, there is also one a located inside the pan.
So, those of you that want a complete tranny service, you might want to consider pulling the pan for the internal filter as well.
Hope this helps with those with the Duramax/Allison combo.
