When I install the converter,TCI 3000 will i have to block off or bypass the "pulse width modulater"?or can tuning take care of it?This is on a 03 chevy silverado.I have HP Tuners..

 

The converter has nothing to do with the PWM, it is
more a victim of it. I have had to jack the low-load
line pressure up quite a bit to keep from having ridiculous
slip (like code setting) when locked on that converter.
It has gotten worse with age. I think this converter (if
we're talking the LS1 Streetfighter) is way short on
clutch for any truck that actually has to work for a
living.

 

The Trans-Go Junior & Hi-Performance Shift kits have the valve that eliminates the PWM in their kits. I install this valve in every one of my units.

 

Thanks!!
