I am working on a 2004 6.0 litre truck with a 4l65 transmission. i have been trying to firm up the shifts using the force motor current but it really has no effect. does anyone have any calibrations i could try or sugestions.
Thanks for your help:help2:

Decrease the shift time. The force motor tables need to be lowered.

Decrease shift time as Al said and then also decrease torque reduction... adjust to suit.

TFM/PCS table works in inverse manner... going lower increases pressure

(1.1A == 0 psi; 0.0A == 96psi)

It might be a good idea to leave this table stock, and adjust shift feel using these tables:
- shift time D1108, D1109, D1110,
- torque reduction D0801, D0802, D0803,
- shift pressure D0701, D0702, D0703.


Also, you may want to zero play with the temperature adjust tables D0704, D0706, D0708 and the high pressure adjust table D1107...
I haven't played with these particular tables very much to be able to say the magnitude of their effect.
