I installed this converter on my 2011 z71 with a 100 shot on it. Before I did I had the converter modified to increase stall speed about 300 rpm. Great mod to do. I have since sold the truck and the guy that bought it plows snow with it. Hes had no issues with it and doesnt know its in there, but he always comments how well the truck runs.
