Hypothesis on transmission

[Jacob]

Okay so I didn’t find anyone talking about this yet but I figured I start a new thread. My thought:

The transmission in our Rangers learn from our driving habits. After driving long enough, many run into issues with gears 3/4/5.

I believe the issue stems from the “learning” the CPU does and it eventually causes the bad shifting.

The owner, fearing the tranny is crapping out, goes to Ford to have the system worked on. Ford simply erases the memory of the transmission learning… BOOM! The tranny feels great again.

I just recently un-tuned by truck which wipes the memory. Suddenly my truck is shifting beautifully again.

This is only a hypothesis at this point but if others on here with bad shifting want to help test it with their tuners, I think this could be a solution.

i wonder if it is possible to stop the learn procedure and just have it shift- you know, like a transmission lol.

Seems much too rational for Ford to implement...

How dare you try to use logic in a Situation like this!

I've mentioned this before.

First, if you're an inconsistent driver (Mr. Walker one day, and Mr. Wheel-Spinner the next), you will indeed have issues with hard shifts, delayed shifting, and other maladies. Ford's Performance Tune does help a lot, but it isn't a panacea.

When you are acting like Mr. Wheel-Spinner, then use Sports mode, not Drive! While there is some memory overlap between Sports mode and Drive, for the most part their learned responses are separate.

I've started to use sport mode more often especially when legally passing someone or merging on the highway/changing lanes. Love engaging the prindle.
Wonder if it's the same when driving in tow mode having an overlap like you suggested.

Which tune were you running? Maybe the tranny programming of your tune was worse than stock?

The day I changed the fluid in my transfer case and rear diff, all my transmission/shifting issues disappeared and have never returned. It's as smooth as butter.
I don't know which one of them solved the problem as I did both changes at the same time.

This reminded me of a classic from back when Disney was actually good.

I know AMSOIL is good but this makes no sense to me..
I am glad it worked for you, did your MGP go up?

My transmission was replaced with a new unit and it's been working perfectly! Weird...

I said this in another thread. I believe it’s the valve bodies of our trannys that starts the series of events that causes catastrophic failures. If the timing is off because of stiction or gumming up things start slamming, clutch packs and more metal based debris then enters the fluid path. We got magnetic solenoids so where do you think all that metal particulate goes! The snowball disintegration failure begins. More magnets in the pan might help tons

I was running the bully dog 91 performance tune. Funny thing is I got the tune to help my issues with the tranny. When I first put the tube on, it was like brand new. Shifts were butter smooth. Then time past and bam, back to bad shifts. Hence why I think this could be one of the culprits behind the tranny issues.

misfit I have a goal, to push this ranger’s transmission till it self implodes and leaves me an angry, stranded mess on the side of the road.

How many miles do you have before you reach 95K?

I spoke with someone who works on high end transmissions and the first thing he said was that the 10r80 valve body(ies?) needed to be drilled out before the shifting could be reprogrammed and work smoothly and reliably.
