, all srt's are auto, all srt6's have 3.07 and and all others have 3.27 not 100% sure about the manual trans but i am 90% sure all std shift also have the 3.27 in otherwords only the srt has a different ratio,,and yes all crossfites have the same diff. but, 3.27 with a different ratio to answer your question the auto and std shift has the same diff and ratio except the srt which has the 3.07
did i repete myself i hope you understand anyway. jim
