Re: C4 squeals on gear change and burns clutches
"I" think your problem is in the valve body. I suggest an aftermarket , dedicated design, manual valve body . My early 24 spline C4 has far fewer modifications and north of 500 hp with over 1,000 runs on it and is trouble free. I use a Winters brand reverse pattern valve body. The only downside for you might be the lack of low gear band apply , so it "freewheels" when you let off the gas in low gear.
Hopefully Gregaust will give his expert opinion too.
