4l80 6.0 Shift tuning issue

[swsmotorsports]

So, i have a mildly built 6.0 with a jakes stage 3 4l80e with a 25-2700rpm stall that shifts VERY quickly into 4th and won't upshift unless you really step on it. as an example, 35MPH 25% TPS and 4th gear with the TCC locked. That cant be right. I'm fairly comfortable with engine tuning, but I need someone to help me with the trans.

You will want to download the bluecat trans tool and remap your shift points.

Also you may want to fix your gear and tire size with the wizard and make sure the values in bluecat matches those in the tune.
