First time snapped the stock shaft, rebuild with Exedy clutches and stock shaft, second time snapped the stock shaft again. Installed TCS shaft and snapped again...

We think it's either a bad Lund tune or bad converter. Aftermarket converter is on the way. If it snaps for a 4th time Lund will get a fat bill to pay!

Sooooo.... if read correctly, (3) of you had your vehicles (w/6R80s) "tuned" by the same shop or individual and so far, all (3) have experienced the same failure with the 6R80 - is that true?

If so, the next question I have is:
What has the "Tuner" said about the failures?

I have same problem with my 2016 gt tune by lund. BUT!!!!
I baught the car with is already now it sits and it only has 20000 miles. Have to build up my savings to get it repaired. Thanks for info guys. Next thing save up more money and get a tune that really does work for the car because whatever the lun is sending everybody it's not working is costing people money should be a class action kickin a**
