In my experience, if you go in with knowledge, some information and background and escalate your concern- they usually work with you. I was offered they cover something out of warranty 50%. So while he might not get it for free, walking in and acknowledging GM has a known problem with the gearbox - they may be willing to work with you.

 

Never hurts to try, worst they can say is no which leaves you in the same spot as you started.

BTW a 3 year 100K warranty? Most people cover about 12K a year. They feel pretty safe with giving the illusion of reliable without actually delivering on it very often. 

 

Ask how many 6L80E failures there are when mounted behind the 4.3 V6. (next to none)

They don't use the JMBX converter  

And no, the V6 unit will not fit or work with the V8's

Long time lurker and first time poster. So what you’re saying is that the 6l80s behind a 4.3 hold up better?

Yes. They use a different torque converter that isn't prone to self destruction. They will fair even better if a guy takes steps to keep the fluid cool, clean and changed. This also works for the V8 units too but you still have that converter issue. 

 

This does not mean that the V8 units can't last. Many do. And yet many don't. Few V6 units have ever failed.
