I did not know such a thing (CDV) existed, I have had my SRT 392 for a year and did not realize that CDV was to blame for the 1-2 shift issues and the notchyness of the gearshifts. I am convinced that removing this junk is going to fix issues I am having with shifting.. But the question is how does this impact warranty ? I assume they are not going to know unless they pull it apart and look at it or I tell them.. But are there warranty implications ? Does it put more stress on the transmission (assuming I am good driver) ?
