The reminder reads that it was reset 2,1xx miles ago
That is why i want to find the invoice
it will give me the date & mileage at the time the oil change was done

At my dealership they no longer put the oil service sticker on the windshield or the driver door

They never put the correct Oil Type sticker under the hood for when they changed the ECO-Diesel SAE Weight
They told me that they don't have any stick on stickers, that i should write it in my Owners Manual

I told them that some Dodge Technician might go by the old sticker that is still under the hood.
They just walk away mumbling

In the last year, every one of the Service Writers is new
7 new Service Writers just in the regular service area, i have not been over to the Commercial area, where they have their own Service Writers & techs

My dad and I have made a habit of writing oil change date and milage on the upper left corner of the windshield with a sharpie, in all our trucks, tractors, and basically anything else. Works extremely well, and can be wiped off at the next oil change. Also, we write the exact date and milage, not a predicted date and milage to have it changed again. We prefer to do that math in our head. Just ideas, not set in stone, but it works for us!!

My truck has 52,000 miles on her now. Bought it used 2 Junes ago with 33K on it. I change the engine oil/rotate the tires every 5K.

When are you guys changing out your diffs, T-case and transmission fluids? I read the owners manual and it does not mention anything about my 8 speed ZF trans maintenance schedule. Apparently Mopar feels it's a truck life fluid. I did a quick search and found ZF suggests 75-90 thousand miles. I do the fluid changes myself and have watched the transmission fluid change procedure several times. Looks like a PIA with a Hemi but I'll get it.

On my Jeep I change the oil every 5K. Transmission, T-case and diffs every 50K and radiator flush every 75K. We have 180,000 miles on her now. Bought this one new. No issues to date.

I'm thinking I'm gonna more or less follow the maintenance interval that I do on our Jeep. I just want to get an idea what you guys are doing.

Thoughts?

I once owned a 1990 GMC Suburban SLE. I bought it with 116,000 miles on it in October, 1998 from the Pontiac/GMC dealer where I worked as an Automatic transmission specialist. I was able to access previous maintenance records because the elderly couple who had bought it there brand new were sticklers for having all proper timely maintenance done there at that dealer. They were also from the "great generation" who believed that 100,000 miles was the end-all finale of any car or truck, thus, they traded off a perfectly good vehicle borne of outdated urban legend. From that point after I bought it, every August, I performed a complete fluid change, new air filter, trans filter, fuel filter, distributor cap and rotor, had the tires rotated and balanced, and replaced the serpentine accessory drive belt.. Every other year, I flushed the brake fluid. Every third year, it got new spark plugs. In 2002, I rebuilt the front end and replaced the factory shocks. The truck went 400 thousand miles before it was towed away to the salvage yard.

Infer what you want to, but I believe that the use of GM AC/Delco parts and recommended fluids had a lot to do with it's longevity. I completely ignored GM's recommended maintenance interval, due to the fact that the authors of those recommends can't be everywhere, thus the recommended time/mileage intervals were subjective at best. It never had to have a replacement engine or differential, but it did have to have the MD8 (4L60) transmission replaced at about 300,000 miles.

P.S. I towed a LOT with that truck NEVER IN OVERDRIVE!; took it on many long trips, and used it a lot. It wasn't a garage queen or any such matter.

Thanks for this experience! Pretty much what I plan on doing. Tomorrow is going to be nice here so I'm gonna do the oil, trans, diffs and transfer case fluids. I'll rotate the tires as well.

Just over 55 thousand miles on her now.

Use good oils if you want long life. If you have Chrysler RFE Trans, Red Line ATF+C is tops, Amsoil Multivehicle ATF next, MOPAR ATF+4 a distant third (only one that is conventional API Group III synthetic oil).

Transfer case depends. If you have a part time 4WD Borg Warner chain drive, you can use ATF. BG44-46 model. If you have full time 4WD ('Auto' button), I'm not sure what that takes for the clutches in it.

Diff's can take GL-5 gear oil without limited slip additive if both aren't LS. If your rear diff has limited slip, then you need LS additized oil, or unadditized oil + a separate additive bottle. If you have all gear antilock torsen diff like me, you don't need any LS. MOPAR and Mobil 1 Delvac Gear Oil are good.

Problem with that is I have an 8 speed transmission. As I said. no mention of a ZF transmission oil change recommendation.

Your manual will have the info for your transmission.

 

[Dale Hartley]

Very odd that Dodge, or Ram in this case does not put a definitive mileage recommendation for this transmission. And as you said ZF wants in changed between 70,000 and 90,000 miles.

I had mine done a t Shop and cost of $600.00 and bought the pan from Amazon. but could have bought a cheaper aluminum pan Autotecnica pan for around $126.00 on Eaby but arrived to late . have a 8 speed trans 8hp70 , used a Dorman pan Plastic with replacable filter .
