i usually use mph as the marker on the 1-2 shift at a minimum....but make sure your mph markers for both are setup properly otherwise you'll be chasing your tail.

im gonna try 5400 for 1-2 and 5300 for 3-4


I searched the database of hptuner files...I can't belive no one else has a stock internals 4000-4400stall + 3.73 tune on there....


Anyone else have an examples of what they have used?

What i did was set it so that my partial throttle tables controlled the shifts. This is proving more consistent than letting it use the WOT shift table.

My car is being told with 3.73s to change at 113kph and that is making it shift when warm at a steady 6400rpm.

To make it only use the partial shift tables - you set it so that it has to go over 100% to start the WOT tables (which is cant do) - then you dont have to satisfy 2 criteria speed and rpm. Just the speed in the partial shift tables at WOT

I have similar problem, stall is 2800 and gears are 3.93. It's gonna be a trial and error.

So you set {D1206} WOT Shift Mode Upper Threshold to 100.00 and this makes the PCM use the part throttle tables only?

I would increase the rev limiter to about 6700 until you get it figured out.
Reving to 6700 should be 100% okay, and will give you enough room to make changes.
