and just to add, this ONLY should be done once something has been changed in the tranny and not just as an attempt to remove the harsh shifting.

I'm getting odd tranny behavious in my 6hp26 and i have been debating on buying a new rebuilt valve body with new solenoids already installed from https://revmaxconverters.com/product...y-mechatronic/

I thought of doing that too but I didn't want to spend that much. This is a reman VB which is better than replacing solenoids. I rebuilt my 5hp24 VB and it's not a big deal. You can buy the kit for 6hp26 and do it yourself.

Now, my understanding from what I read so far is that the re-learning procedure is required after the firmware update or clearing adaptations.
At Vitek, Aaron is the expert on this and he does it always after the firmware update.
What are the symptoms in your case? Only the 1-2 harsh shift?
