I have one of those rare 4 speed overdrive transmissions, RPO MM7 Np A833, I like it but with 33s it is very high geared I rarely get into O/D and 1st and reverse are just to high, I currently have 373s but I'm thinking the 456s may be the answer, for those who don't know the gear ratio is very close to the 700r auto. Anybody care to give me their thoughts?
