well, you just answered a question I was going to ask...my memory goes back to chevy days, but increasing pressure for upshifts would also be there for a down shift...I destroyed a gm400 by down shifting it...of course today, more electronics and safe guards built in...but, don't want to risk it for a few tenths...patiently waiting DJ...good luck...Rudy, did get to talk to my engineer buddy. He agreed to hook up with you one evening you have free. He will pass any info to the company you and I discussed...
