segment swap to 4L80E

I need a stock file for a a segment swap os 12212156 since the os has to match I am assuming

I don't have one on this computer but just log into your customer account on the HP Tuners website.

Then click devices and there should be a tune repository in there that you can find a tune from. Should be very straight forward.

Or just type 12212156 into the search bar, it should pull up threads with that being said and likely tune files with it.

Thanks for the help

what year make and model u working on

you can open a support ticket, we have 4l80 segment swap files for a good portion of the most common operating systems.
