I (Myself) actually did my own leg work months ago and took the effort to contact ZF themselves. The tech I talked to instructed me of the Service They recommended for this transmission. I will say this (The Lifetime) fluid idea was Rams not ZF. As well as the coolant / ATF heat exchanger. As of late & few ideas that popped up with the conversation with the ZF tech. I added a Spin-On filter kit to my 8HP70. Along with a Very Strong Ceramic C8 grade Neodymium magnet inside the spin-on filter. As well as 4 on the outside of the filter. Cleaner fluid at every pass will prolong the life of the expensive fluid which will help extend service intervals. Which is a win/win especially when the plastic composite pan cost over $200. Hopefully the price will drop over time. Like I have said oh maybe 17 times or so I don't know I quit counting. I am doing basic preventive maintenance for those miles after my warranty is done/expired/out/over. Preparation for that time when my Ram reaches 100,001 miles or that quickly approaching 5 years has past! Since I have plans on keeping my Ram well beyond that. I will do maintenance now to prepare for Those Miles. Ram only cares about getting you through that 5 Year/100K period. For me that 5 years is Fast approaching. I don't even have 20k miles on my Ram yet! Don't you all fret over my maintenance on my 8HP70. We will be just fine. One thing to remember: Just because someone else thought of it and is doing it (with outstanding results) Even though YOU didn't think of it (OR) are not doing it--->Does not mean it's wrong! There is a very good chance when my 5 years comes and goes my Ram will barely have 40k miles on her. There for that puts a lot of future miles going foreword with Zero warranty. Yup I'm doing the right thing! My future plans as of today are: At the 25K mile mark replace the spin-on ATF filter / fill filter w/Red Line D6). At the 50,000 mile mark drain the pan and refill with Red Line D6 and change out the spin-on ATF filter. At the 100,000 mile mark drop the pan and replace. And refill with Red Line D6 / replace the spin-on ATF filter / fill filter with Red Line D6. Each new spin-on ATF filter will get a New Ceramic C8 magnet inside.
