Y’all sent a transmission filter that’s not on my truck?
Hey Kevin! Thanks for letting us know about this. If you can send an email over to sales@docsdiesel.com, we can look into this and get this fixed up for you!Thank you,Doc's DieselCustomer Support
Product came in timely manner, I have driving truck about 1500 miles, so far truck runs amazing, will use again.
I was using archoil but figured would try Doc's and so far it seems to be better so far I'm getting 150 miles more between regens. Will keep you posted
Added to 2003 5.9 Dodge it seems like motor is not making as much noise.Added to 2011 Duramax as of now don’t see or hear anything positive.In both cases I assume it’s helping.Next time I make a long run I’ll hand calculate mpg and see if any difference is there.
Great increase fuel mileage and power
