Talking Re: 4L60E shift issues.

I read a similar problem with a 4L60-E with a Corvette that had been modified with new internal heavy duty parts, and a shift kit. the tech mentioned something about "Torque Management" program in the PCM that conflicts exactly opposite of what we are trying to do with a shift kit, fights it all the way, here is one post I found- good reading.....
