When you become a GM. how long do you train for??

Will in engine swap on a GM car void the transmission power train warranty?

• I just swaped the engine to my 2007 colbalt cause GM denied the powertrain on the engine for lack of oil change paperwork they told me my power train on transmission would still be good, but is that if GM dealers only do the work and brand new engine? cause put a used engine in with 33,000 miles certified mechanics did it. but just got car back and feels like a shift kit was installed the way it's griping the gears and mechanic said might just be from sitting for 5 months with out being turned on or driven but if dosen't stop will have to take it in just wondering if it still be covered

• Answer:

  You have a 4 y/o car that you had to put a new motor in?????? Sorry I had to ask. Well since you didn't ask the GM people *before* you did your engine swap I would say your chances are a bit iffy. You had *major* mechanical work performed in a non-GM shop by non-GM certified mechanics. But, you never know. I would: 1) READ the power train warranty and see what it says. 2) If you can't find your answer from reading the warranty then talk with your local GM dealer. My opinion: I would be very surprised if GM would honor any part of the power train warranty at this point.
