    Basic Pressure Increase?

    If you guys were going to do a 4l60e trans shift pressure increase, how much would you go in the 1st shot. Say on a 400 rwhp truck?

    Thanks

    I generally take the FMC + and - tables, mult by .97 to .95, and then start increasing the shifts by 1.1.

    If it's not firm enough, I take my stock values and mult by 1.15, and test. I always use the stock values so I know where my base is, vs working off the 1.1 or 1.15 values.
