Hi everyone i am new to this group and have an 06 300srt 6.1,, i have a question about the nag 1 tranny,, i wanted to know if there is any aftermarket option out there to change out 5th fifth gear only,, tacking out at 2200 at 70mph and wanted to tone that down 4 to 500 rpms if possible less strain on the 6.1 and slightly better mpg,, i dont get out of fourth around here anyway and dont see fifth for the 1/4 mile runs anyway so willing to give up the taller gear for better highway operation,, thanks Sent from my SM-G973U using Tapatalk
