Transmission callibrations

[kmidkiff]

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

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.
