Normal duty/ severe service 2022 ram 3500 ho aisin

[Turbo Terry]

So I’m mostly confused about this . I haul a 3000 lbs slide in truck camper for about 3-4 months a year in the summer in alaska and northern climates . Sometimes I pull a 2000 lbs trailer. Maybe 3 times in the summer. This mostly pertains to aisin automatic transmission. The truck is kept in a heated garage in the winter and is drove around a bit as a daily driver. So what am I normal or severe duty?

 

[Topzide]

I think that your on the border with payload weight but don't think you're severe duty with temps. How about the dust load you see? When you think about what most of these trucks tow on a daily basis, your truck isn't breaking a sweat!

 

[Turbo Terry]

Not so much dust . Mostly summer construction season. But we do have some very rough roads I think I’m on the low end of severe duty.Yes new air filters are my friend in the summer

Short trips is severe duty

Chase down the fine print

 

[Turbo Terry]

What pray tell then is a short trip . 8 miles to work out of a heated garage plugged in on a timer 2 hours before go home time is a short trip I suppose but retired running errands out of a heated garage say 25 miles around town running and moving is that a short trip no idling on the 6.7 like the 5.9. Is that a short trip?

 

[Diesel85]

With that 25 miles of running around town, does the engine get fully warmed up?

If not, that would be considered severe duty, especially with condensation in the oil.

I once had a retired neighbor that drove their 1998 F150 with the 4.6l V8 only 4 miles a day. He ended up having some health issues that set him back and he wanted me to change his oil during the winter. So I found a reasonably warm day (probably in 30's outside), and first problem I found, was I couldn't get the dipstick out of the tube! After much effort, I found that the inside of the dipstick tube rusted the dipstick/o-rings in place due to excessive moisture. I then popped off the oil cap, and found what looked to be slushy ice/oil in his oil fill, all the way down into the engine.

I pulled it into my shop, turned the heat on, got it up to about 80F in the shop and let the truck cook for about half the day before working on it. I had some extra oil in the shop I didn't plan on using on any of my vehicles, and I did the first fill (without removing the existing oil filter) and started the truck and got it nice and hot. Then I changed the oil and filter with what he provided.

Above is an example of extreme case of severe duty use.

I appreciate that story. Severe for sure. When I go out now I try very hard to drive it enough to get it hot. The warm front and fast idle is also a good thing to help with this. Thanks for all the reply’s. I think I’m at the very low end of severe duty

Short trips = under 45-miles.

Short trips = under 45-miles.

And not getting the engine up to operating temp! Get the truck out on the highway and get up to temp and try to maintain a good cruising speed to allow the truck to do it thing. I always go the longer way back home to allow a good heat cycle!

These trucks don't have a normal service or severe service maintenance schedule. The Aisin gets a 30K/24 month fluid change and a 60K/48month filter change regardless of use.

The only fluids that mention service for change intervals are the differentials and transfer case fluid.

 

[Turbo Terry]

A good point

 

[Turbo Terry]

Or 24 months which ever comes first which makes severe duty normal duty very confusing. So at 24 months 20 k the fluid needs changed to keep the warranty good. It not a very good system .it’s almost like they want you to screw up so they can void your warranty.

There is no normal or severe duty, so nothing to confuse there.

Months or miles, whichever occurs first. They aren’t trying to screw you up, they are saying you can’t run fluid or filters for 10 years if you only do 1,500 miles a year.

 

[Turbo Terry]

Yes I understand that. Don’t have to like it though. In 1983 I bought a 83 ford f250 for 12 k. New. One year warranty or 12k. No electronics basic truck. Now we have all the fancy stuff . But I do like the power and smoothness of my new truck
It’s awesome. Sorry rant over move on

1). Cut down engine cold start number per week. Combined trips.

2). Then going to farthest point on map list via biggest road at steady-state 45-MPH or better.

3). Work back towards home with fuel-efficient routing (high average MPH; lowest engine run time; no left turns, etc).

Practices for longevity pretty much identical to fuel economy.

Engine Oil Temp is the mark. Lags behind coolant in time/miles, and prefers a load to get high enough temp to burn off condensation in crankcase.

Solo/Empty is not design description (poor utilization).

Rams Maintenace schedule is generic, not really impressed with it. Police and taxi is severe, how many Ram HD diesels are in that schedule? Yet, no difference between normal and severe for the engine oil or transmission. I adjust the schedule for my use. Just getting in heavy traffic or major stop lights will bring my transmission temps up to 190 degrees.

The 68RFE actually does have a normal/severe schedule, but 120K miles/60k normal/severe. They are both too long.

My small Ford Escape suv considers a simple roof top carrier as severe. So, your cab over camper should qualify. If you are like me and keep your trucks forever, I would error on the conservative side.

I recommend changing out your power steering reservoir. You don't want a pump or box failure. A catastrophic failure of one or the other will haunt you forever.

well, Im not going to worry right now.. I did not see the "or 24 mo" on the AISIN and my truck sat in the shop most of this year... it got its oil change at 29600 / 30 mo... I'll do the filter @ 48 tho I guess.

How is it generic? It's pretty clear when and what to change, and covers everything except brake fluid.

While there aren't many in the police/taxi service I have seen them as police vehicles.

190° is nothing for ATF+4, its even nothing for ASRC which isn't even synthetic.

The 68RFE actually does have a normal/severe schedule, but 120K miles/60k normal/severe. They are both too long.

Why do you think they are too long? Modern filter, fluids, and engineering are very different than 2-3 vehicle generations ago. Nothing wrong with what Ram has published for the 68RFE. You tow frequently, so 60K/48 month trans fluid and filter services. A highway princess can easily go 120K/96 months on ATF+4.

The engine doesn't really care how you get to 12 months, 15K miles, or 500 hours... no need for a different schedule. It also should tell you to change it sooner if you are operating it in a manner that requires more frequent service. This engine is very easy on oil.

You can't really compare severe use on a crossover SUV to a HD pickup, one was designed for a soccer mom and one was designed to work.

For example both my Ram and my 4Runner have Aisin transmissions that utilize Aisin ATF-0T4 (Toyota calls it T-TIV and Ram calls is ASRC), but their service schedules are very different. We know Ram says 30K/24 month fluid and 60K/48 month filter changes, while Toyota says fluid and filter for life. The OEM's have already adjusted the service intervals for the intended use of the vehicle, and they aren't applicable to each other. The severe service on a Ford Escape means nothing to a Ram HD, nothing.

I recommend changing out your power steering reservoir. You don't want a pump or box failure. A catastrophic failure of one or the other will haunt you forever.

This is really the only place I think the OEM service schedule falls short, but at least it's in there as it hasn't been in the past.

I could explain my reasoning till the cows come home but it would fall on deaf ears, so I won't.

I will say this: Do you know why/what is causing the 190 degree temps? The 190 is okay but the cause is reason enough to care. The stress that raises the temp is hard on the fluid, period.

I stand by my comments and will adjust my schedule for my use. You use Ram. we will both be happy.

Sure do, but ATF +4 isn't your daddy's ATF fluid.
