That sounds like a bandaid solution to a improper design!
Is there not a way to increase the line pressure? On my old Dodge 47RE, a Trans-go shift kit increased the pressure high enough so that the stock V10 can't slip the converter clutch at any throttle opening.
The 6L90 is a tougher transmission, and the 6.0 is a weaker engine (torque wise), can't see there being any trouble. If they can run a de-tuned Duramax on this unit, how can a stock 6.0 slip the clutch?
I agree, although it seems to be working other than causing more powertrain heat.
I don't think line pressure will help. It's just not enough surface area in the torque converter clutch. The diesel and the gas motors don't use the same torque converters because of their requires stall speeds, and clearly they must have changed more than just turbine profiles.
TSB is GM#14745. Sorry I can't post the text, since I'm no longer subscribed to any repair databases. Applies to 2010-2014 models. 2015 must have an upgraded T/C, and the company that makes the purple ones has an upgrade as well.
