Can anyone help me understand why i was able to set my shift points exactly where i wanted them with the stock rear end, and now that i switched to 3.73's my 1-2 shifts prematurely and 2-3 blows past my MPH to my rev limit??? I have a 2000 SS w/ Aubern diff, had 3.23's now Motive 3.73's.

 

did you change your gear ratio in edit?

I sure did. I just can't figure it out. Esp. since it worked just fine with the 3.23's and now is screwy with the 3.73's

 

Gotta set the part throttle shift via the edit..
Mine needs it done too since adding a different gear..

JS, Would you care to ellaborate for us please? Once 100% TPS is set what range is required in PT ranges and why? Thanks.

 

By part throttle, what are you meaning. I did adjust most if not all the shift point across the whole throttle range on the chart and I matched the Performance, Hot and cruise to the normal chart. Is there something else?

 

what i did was only move your MPH
dont touch the rpm, leave it at 6000.

if your hitting the limiter, lower your mph until it shifts where you want it.
i have mine right now at
1-2 35 - 6000
2-3 65 - 6000
