I have a th400 in my car and have got the B&M recalibration kit, currently at WOT my tranny is shifting at 4500 RPM. My question is what should I do first? I understand how to do it I just dont know how the different springs/ weights will effect my shift points. I am wanting to have my WOT shifts come at 6000 RPM's. I'm sure someone knows what I need to do so I'm not just guessing. Thanks in advance.
