Tranny fluid change

[azdryheat]

Got 70,000 miles on the current ATF oil, so today it and the spin-on filter got changed. I also dropped the pan to see if there was any sludge and it was clean. Love this Duramax/Allison combo.

Apparently you have magic trucks and the wrong women...

Doesn't Ram include fresh clean fluid when you order a new 2022. Just think it would come with fresh engine oil, tranny oil, new brakes, tires and antifreeze. New paint and chrome, new seats, updated nav system, 425 HP and 1075 lbft of torque plus bumper to bumper warranty and all for just three easy payments of $9,000 plus a 1/2 worn out, tired old sheep that is ready to be turned out to pasture. What are you waiting for ... or if you really want to have something to get cranked up about you could turn off one block sooner.

I have always liked how you can rationalize buying a new truck when the mood hits. :B

Yeah, I feel sorry for the poor sob’s that get 4x’s used trucks. I’ve never been able
to subscribe to the run until you trade it in, maintenance be dammned, approach.

^Interesting.
I haven’t done it yet, but on the 68rfe I recall reading about disconnecting back by the trans to do a fluid replacement. Maybe to bypass a thermostat that recycles fluid until hot, like you experienced.

That said, 12V, why couldn’t you do a trans fluid replacement like any other trans via the cooler line?

When it was time for my Son's 15 to be serviced we poped the line by the radiator all we got out was a dribble. My 11 68rfe worked like a dream.

Sounds like there is some type of solenoid on the side of the trans. Wish I knew where to safely tap the converter.

^^^ Some transmissions have a bypass valve that allows fluid to bypass the cooler unless it is hot.

The "YET" part is what scares me. If the filter says tighten a certain amount after contact I do so. Honestly if a filter can be removed by hand after 5-15,000 miles that is loose IMHO.

Ron, tighten by hand the 3/4 turn past gasket contact, it is tight. I didn’t say it spun off easily at change. I wear a playtex rubber kitchen glove for heat resistance and better grip. I have been doing this way since an oil and filter change on Dad’s 59 Ford 352. Destroyed the spin on filter getting it off had gone on with clean oil on the gasket, and likely a full turn after gasket contact, that was about 1967,!
The 2001 ran 10k between changes.

Mechanics trick: use old oil on the gasket. Then it will always release for the next change out.... Do not worry about a couple of drops of old oil on the gasket.

Why old oil vs new oil?

I did... By having to change out the transmission fluid every 30k miles you don't have to worry about flushing the transmission.

I don't "FLUSH" my transmissions.

Don't think you answered my question. Did you change "ALL" your trans fluid when it was serviced?????

No... Simply drained the oil pan at 100k miles. At 180k miles I removed the oil pan replaced the filter, cleaned the particles on the large magnet and refilled. Currently at 214k miles and transmission shifts and performs excellent.

Keep in mind Ford recommends a 150k mile service so I did perform the first service early.
