Soft lock-up
Soft lock-up I have a 2003 C5 with a level 5 4l60e 3.90's and a PT4000. The trans builder created a lazy lock-up and said if I wanted he would firm it up. He's been around a long time and has now disappeared. I'm planning on trying the following to firm up the lock-up. I'm not planning on locking under WOT, this is for street driving.
TCC PWM min duty cycle: Raise values 20% at a time. This should firm the lock?
TCC pressure apply rate: Raise 10% at a time. This should speed up the apply?
Does this sound right and is it safe?
Thanks
Joe

I was playing around with force motor current(positive),I have EFILive and I noticed when I lowered the current in the zero line pressure row the lockup was softer and when I raised the force motor current the lockup seemed to be alittle harder.Is it my imagination or am I right?................Paul
I don't know how that table affects the converter, but lowering values raises
line pressure and firms up part throttle shifts.
Have you tried what I posted? It will be a week before I can.
