set all the trans codes to "No error Reported" and make sure to leave the SES checked(enabled)
That way all the trans tests happen, and are passed immediately with "no error reported"

though, I believe that trans stuff is not emissions related, so it may not be necessary anyways.

Remember to drive the car for a while, because the readiness test take some driving time to be set to PASS
After you tune it, drive it for a day or two, then scan it to check no DTCs are set, because any DTC will make the car fail, and if you erase DTCs the readiness test are also reset and you have to drive it again.
