Since I have been working on my ram air and have had the entire air box assembly out a few times I notice that my transmission has a sticker on it stating:
Service Replacement Transmission
Remanufactured for General Motors Corp.
Would this mean the my transmission has been replaced some time. If it does it means it was replaced before 51,220 miles. I bought the car of some good friends and they said they never replaced it so it had to be the first owner.
