    Shift RPM

    Hi guys,
    i have several questions regarding trans tuning in my Dodge;

    Q1: What is the winter mode?
    Q2: how to calculate the shifting RPM at WOT for example i have in normal mode 1-2 upshift the output RPM is 1785
    so how to calculate the real shifting RPM
    Q3: which tables are responsible to increase shift firmness or increase shifting pressure at WOT
    Q4: does the output RPM in part throttle (94 - 99% columns) and in WOT tables equal each other or that doesnot matter.

    many thanks in advance for any help.

    Shift RPM is output shaft based. Divide desired engine rpm by trans gear ratio to get output shaft RPM for that gear.
