WTF are you smoking? The SC kit is great. Your choice in converters suck.
I ran a 1600-1800 stall in my red dually it broke and had to put a 2000 stall in that sucked ass..truck was laggy and lethargic comine of the line.. 1st gear final drive is danr near the same between my lmm.Alison with 3.73 and lbz/4L85 with 4.63, 11.56/11.48 respectively
The OEM will stall about 2500-2800 just tring to nicely move 25k up a hill.. Going to be even worse when I bump to 36k gross..
The 1056 is way too loose for what I do. Way too mcuh slip
The OEM Alison has a 1000+rpm drop on lockup and you barely see rpm drop on a 1-2 shift. It won't lock till almost 30mph in TH with a full load going up hill
The 1600-1800 500rpm drop on lock up and 750rpm drop on a 1-2 unlock shift.
I'm not looking to drag race.. I have all this nice gearing that gets wasted with too much stall..
I have been there done that it worked extremely well. Phily taylor is only one thus far that say that can meet said needs.. Everyone else for the most part has stopped short of calling me an idiot
