You might actually be right on that 1st gear, I know that 2nd gear is 1.45 on both and 1:1 in 3rd and the OD ratio is also the same since the OD section is interchangeable between all of them.
I thought I remember seeing that they had made the 1st (low gear) ratio the same between them when they came out with the OD trannys.
I know that with the old 3 speeds the 727 and 904s were the same ratios throughout, until they came out with the "998" and "999" which for all intents and purposes are based off the 904, 904, 998 and 999 are still all versions of the "lighter duty transmission" with the 727 being the heavier duty. The 998/999 had the 2.7something 1st gear while the "regular" 904 and 727 were 2.45 low gear.
gives you an idea how long I have been messing with Dodge products.
one of my current ones is a '78 Sport Fury and another I own is an 80 Volare. been driving for 32 years and have never owned anything but a Dodge or Plymouth although I often get stuck working on other brands.... I must say though that I draw the line at Ford and Chevy as far as what I will work on, Honda Toyota Hyundai etc I won't even let park in my driveway.... (I know, getting off topic here)

1.54 vs 1.45 2nd 42 vs 46
(Looked it up again)
And yes, third and fourth are the same between them.

Thanks Don. The learning curve for me was getting taken to the cleaners by a guy who did not rebuild my trans as contracted he exchanged it and it was messed up to boot. So now I don't have matching numbers any longer and a trans that has been running OK since I had it fixed but not optimum. This goes on the list "Get 46rh-rebuild it-install." I won't hold my breath i've got years worth of half done projects to get through first.

Are you interested in sell a rear pinion shaft slip yoke from one of them?
