Just completed the trans swap in my LLY. Built trans came out of and LB7. Of course im getting the tcm code for the G Pressure solenoid, as the LB7 does not have it And the LLY one did. I know I can take the solenoid out of the lly trans, pull the pan, plug it in, and just secure it inside in order to clear the code. I was able to aquire the old trans tune for that LB7 transmission. Obviously the OS from the LB7 and the LLY is different when we pull them up on efi live. My question is, can i change the OS number from the LLY tcm to the LB7 tcm in order to put the old LB7 tune in my LLY tcm? I do not want to swap valve bodies because this valve body has had a lot of work done to it. Sorry for the terrible image quality.
