I definitely think it is "better" to service the transmission. Not arguing but just making some comments. The question is exactly what does "better" mean in this situation. Does it mean the transmission will last twice as long if you service it, or only last an extra 10k? I don't know the answer but again guarantee those numbers were considered prior to Ram writing that in the owner's manual. The basic concept is called ROI (return on investment). In my business there are tons of things that you could do to make the process "better", but if being "better" means spending $1,000,000 on new equipment that will save you $10,000 per year it doesn't make financial sense to do so. Not saying that Ram, or any other manufacturer, always makes the best choice but those things are considered. Part of the whole "lifetime" fluid idea is driven by the people who buy the trucks and like that you shouldn't have to service it (let's get real, what percentage of people actually change the trans fluid, coolant, brake fluid, etc... as recommended in the owner's manual!). For ROI, Ram is making a decision if offering "lifetime fluid" will attract more buyers to the truck, along with making sure they have "reasonable" lifespan in the trans by doing so. Also, on average how long do a lot of people own a new truck before trading it in?
Regarding towing in 6th (direct) vs. 7th (OD). Again, is it truly "better" one way or another? If it is better, how much better is it? Nobody on this forum, or any other place on the internet, has any actual data to prove one way or another so it comes down to personal opinion. My opinion is it doesn't matter or make any significant difference in the lifespan of the trans. Other people will adamantly disagree and say the trans will blow up and kill a bus full of nuns if you tow in OD. Neither side has any data to prove one way or another. However I will say I personally was involved in automotive testing around this topic that was performed based on owner's manual recommendations, which rarely ever said anything but recommending using tow/haul mode which typically allowed shifting into OD.
Yep, fair enough, the "how much better" is indeed hard for us to quantify without access to their data. It makes me feel warm and fuzzy inside to take care of my stuff though, so that's worth something right?
