I have used K&N filters for many years and never had an issue with them
I have 127K miles on my original tranny and put my foot into it hard everywhere I go. I have increased shifting firmness with the program, 4.56:1 gears, 37" tires, disabled torque managment, no internal tranny heat exhanger in radiator, run Redline tranny fluid, seperate tranny cooler and change my tranny fluid/filter every 50K. I dont shift when the vehicle is moving. I have never lost a tranny before. Maybe I do something different than the average, I dont know...but I drive it like I stole it and never an issue.
