i got something wrong with my c6 2wd tranny and i took it in and they told me that the converter broke apart into the tranny parts but my truck is still running fine just shiffting a lil different are these guys just tryin to screw me over or are they right

 

Define shifting diffrent... Always get a second opinion if you have doubts. Take it to another tranny shop.

 

I agree. i would get a second opinion. If the shifting is harder, it may only need a good servicing/flushing.

 

more likely filter clogged
