Ive been looking all over and cant find anything anywhere but i swapped the 4l60 out of my truck and put a 4l80 in. My odometer shows up and works and the prndl is lit BUT the rings that show your gear indication dont appear. Has anyone else had this happen before?

You have the correct swap harness?

Did you pin the PCM correctly?

  OK.... so I think it is fixed this time. New updated program required to get this running is #PIT6504 dated Apr 1 , 2026. Appears the applications cover numerous Chevy and GMC vehicles with fwd col, AEB, and LKA options. Hopefully this helps someone out in the future with these issues.

  If the plugs all line up, then it should be okay to go.

  I just delt with this this morning. Already replaced my condenser two years ago. I didn't have to replace my blend door actuator, I just had to do the relearn process and it worked.

  Thanks for the reply. I am reading other articles talking about how it will work if you reuse the ECM from the 2021. Which I can do. But I wont't get any of the additional torque... which I don't really care. I just need it working. Trying to decide if I keep the engine or if I have to return it and go find another engine?

  Hopefully it sounds like they have, if they move this production back in house for the new v-8's. Still though to allow this to go on for over a half decade is shameful imo.
