    Default 4L80E shifting soft

    I have been doing the AutoVE tune on my truck, before starting the process my truck had good firm shifts, now that I've retuned the truck multiple times it is shifting soft. I didn't change anything on the tranny and from what I've read and can the see in my tune everything looks OK. Can someone give my any ideas on why its doing this?

    Here is the currnet tune:
