Sorry for the long winded post but I'm trying to put all the information I have into this: I have an 09 GT. Picked it up as a project car. It ran but engine needed to be rebuilt and transmission was grinding. I verified that all lights/windows, etc worked prior to starting my work. This car had an auto to manual transmission swap done prior to me picking it up. It has an SCT tuner with a manual trans tune in it. Pulled engine and trans, rebuilt engine, put a remanufactured transmission...
