Greetings...Don't want to stir up too much controversy, but I believe the
automatic gearboxes in the MGC (Borg-Warner 35) used a 3.307 ratio
differential. The factory workshoppe manual (MGC Issue #2 #21362 dated 1969)
states on Data Page 3 :
AUTOMATIC GEARBOX
Overall Ratios:
Top - 3.307:1
2nd - 4.795:1
1st - 7.903:1
Reverse - 6.911:1
Early MGCs (up to #4236) used either a 3.07 for standard transmission or a
3.307 with overdrive transmisison (2.71 with overdrive engaged). Later MGCs
used the 3.307 for standard or the 3.7 (3.03 with overdrive engaged)
differential.
