Rebuilt Transmission?
 

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:

Goodwrench Transmissions
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.

Yea it does great, even with 115,000 on the car. Of course now I have no idea how many miles is on the tranny. I still will have to watch the upper intake it is still the original.
