    4l60e shifting issues

    Hey guys, I'm still fairly new to this tuning thing. I logged a short drive down the road earlier and wanted to post it to see what you guys thought about how the truck is running overall. But especially about how the 1st to 2nd shift is. It is sluggish and not firm at all on that particular shift. 2nd to 3rd is short and firm however. I have the shift time set to .125 in performance and this log was taken in performance mode. The truck also has the corvette servo. Any pointers you guys could give would be greatly appreciated. I'd like to learn this stuff.

    Just by a quick look at the tune, it shouldnt do that. However, i would try what itll do if you zero-out the torque reduction tables. Trans - torque management - torque reduction.
