I have gotten HPtuners and I can not seem to find a way to make the trans shift harder.Under transmission-Auto shift properties-shift pressure-Normal&performance tables-I have adjusted the tables up gradually to my max pressure of 96.I have also adjusted the shift time tables.Still the transmission does not want to shift hard.Oh well guess it is time for a Corvette servo.

 

If you have maxed out the base pressure tables with unsatisfactory results, you can also go to the 'shift pressure modifier' tables for specific up/down shifts or the force motor current table for across the board changes. Lower values in the FMC values = more commanded line pressure.
Although when you say adjusted gradually up to max, do you mean the whole table is maxed at 96 or cell1=1 and increases up to 96 at the last cell?

 

shift kit and servo and then make your pressure tables stock

 

Make sure your Force Motor Current table doesnt have a no-pressure setting at max commanded pressure.

Ie, something like 1100mA in the last column correlating with a 96 commanded pressure. Change that to something like 50mA (inline with the other cells in the rows) If thats the case and you are commanding max pressure, its a invitation to fry your tranny

 

Pulling the torque management will firm it up a little too

 

i didnt quite understand that, do you mean to keep the last row in the force motor table a high value like the stock one 1096 or put in a value like the previous row of say 98..

 

Put the last row something small... Like the previous column, or taper it to be a "little" smaller.

Basically the way the FMC table works, is that the higher the current flowing to the control solenoid yeilds lower line pressure. GM setup the stock table with the last column being a "failsafe" current load. And they could get away with it as their tuning never utilized the max commanded pressure. However, once you get your hands in there, that high value is bad, very bad. Think of it this way, WOT shift, max pressure, but to the PCM the commanded pressure is pratcially nothing. Bye bye tranny.

 

I'm really thinking about going this route as well. I have been playing with my trans tables for the last month and just cannot find the sweet spot.
I wouldn't play around with the force motor table too much, seemed to cause me more problem then it was worth. I'm back to the stock table there with mine.

 

waaaaaaaaay to many horror stories on the web and threads of people roasting the STOCK trannies screwing those force motor tables. Let alone super hard to find that sweet spot. If you are good at and know what your doing obviously that's one thing.

IMHO it's easier to fry you tranny screwing with those tables than it is blowing your motor screwing with your advance table. At least you'll get knock retard and pull back...the tranny will just fry...no warning.

 

dwmanshu, the same can be said with those who command max line pressure at on their pressure tables without atleast replacing the last column of the force motor current table with something that wont result in zero pressure. Still yield a blown tranny.
