I've gone through 2 pumped up 4L65E's in the past 2 years and I lost 4th gear about a month ago. The frist tranny lasted pretty long with teh Procharger but the turbos put out so much more torque that it's just killer the 4L65E. I picked up a 4L80E + all the misc parts and will install it after next month (a couple business trips on the horizon).
