5R110 Re-learn time.
Awhile back I did a coolant flush and disconnected the batteries for the starter to replace that block plug with a Fumoto valve. Well, installed valves on both sides plus a 6.7 starter while I was in there but that's for another thread.
After all was said an done, I was trying to flush the motor and everything with distilled water etc. I was running the Banks Economy tune at the time; had it installed before the battery disconnect and after reinstalling everything.
I guess this would alter the shift re-learn strategy? I have since returned it to stock and tried to do the procedure but is it too late? Do I have to start over with a complete disconnect of the batteries again and do the re-learn procedure over? How long does the re-learn usually take?

Thanks Mark. I was hoping you would respond.
I experienced a flare going into 3rd gear with the tune AFTER I reconnected the batteries. It didn't flare before. I took the tune out in hopes that it would re-learn a little faster or easier.

It will learn with the tune out. All of that learning becomes meaningless when you reinstall the tune. It has to learn all over again because the tune changes everything. Until it learns a flare is not unusual.

I went through this a few weeks ago, flaring and clunking, jerking so bad for short periods I thought for sure something was wrong, but then remembered reading about the TCM relearn and others with the similar issues.

So far I haven't had any clunking or hard shifts since I reconnected the batteries. Just the flare going into third. Since the tune has been out though, it's not done it.
Even though it learns all it's life, how does it take for it to not flare?

We had some problems with 3-5 flare on the stock tune. It's due to the hardware used in that shift. The learning will tune out the flare, usually in 2-4 shifts. If you reinstall the tune it has to learn those characteristics, so you can expect more flares. I couldn't tell you how many because I don't know what the tune does.

It's a Banks Automind tuner/programmer set on Economy mode which is the lowest setting. I talked to them the other day and the tech dept. said that their tunes increase shift pressure a little over stock but I can increase it more manually if I want.
Plus it would only flare when I was getting on it some. Never flared before I disconnected the batteries.

Changing from stock to a tune changes several things. It changes the relationship of pedal position to torque produced, and from what you said it changes the commanded shift pressure. Both of those will change the pressure required to complete the shift in the programmed time. That requires the adaptive software to add or subtract pressure. This is the learning process. Everytime the tune changes the adaptive needs to relearn. Flaring is a normal occurrence when the learning isn't up to date with the changes. Disconnecting the batteries deletes all learning and it starts over.

Thanks again Mark.
I guess I'll stay on the stock tune a little while longer to let it learn it's base strategy so it doesn't flare. It's just about where it was before if I remember correctly. Then I'll reload the tune back in to see if it flares. If it doesn't then I guess I'm good.

As sort of an update, I reloaded the tune about a month and half ago. All this time it will flare a little going into third when it's cold. It won't flare when it's up to full operating temperature. This evening I experienced my worst flare and then a hard shift going into third. I let off and the RPM's dropped some before the hard shift. Then I resumed to drive normal. I guess this is another time I need to take the tune back out right?
Also, I looked under custom tuning options and there is no way to adjust for higher line pressure for this application on this Banks tuner.

So...I figured someone would tell me something; take your tune out, throw that thing out the window lol, something! Is this just a simple matter of the trans needing to learn with the tune out or have I damaged it?
