    Tranny Still going haywire! Help!

    My trans still wiil not shift when commanded, converter locking and unlocking before it is suppose to be,will not downshift to proper passing gear,and seems to hit neutral as like 5500rpm. All started when I changed my gear ratio and let Hp configure my trans settings. Here is my whole tune please check it out and give me suggestions.
    This is driving me nuts!!!!

    Your WOT shift speeds are at 0 mph. I'm no expert but all my cars have a mph in those cells. for example 36 65 99 125.

    Thats because he's using the WOT Shift RPM table to control when it shifts at WOT instead of both Speed & RPM.
    I tried setting it up this way in the past but ran into issues due to this setup and went back to the normal way.
