Automatic transmission options?????
I have a C6 behind a 428 with 3:73 rear gears. Not sure what the rear end is. Dana???? The truck is a 72' F250
The truck originally came with a 302.
It's great driving around town and really seems to love cruising around 45-50 mph.
However, on the highway, anything above 65 and she is screaming.
Are there any tranny options out there that have 4 speed or overdrive that I could drop in? The C6 is a 3 speed.
It's obvious I know very little about AUTOMATICS.
I'm not sure about changing the rear gears. Never have done it. Plus I wouldn't even know what would be a good ratio to change to that would give me less RPM's at 70 mph which about as fast as I really want to cruise on the Highway.
I imagine any tranny option is not going to be cheap but I hate listening to that 428 running hard just to stay in traffic.

Thanks John. How hard is it to change the gear(s) in the rear?

You would need some expensive adaptors to mate anything other than an FE block C6 to your engine.
As for rear gears the highest gears (numerically lower) gears I have ever seen available for a dana 60 are 3.31. There are some gear ratio calculators here on the website so you can play around with what would sound good to you. Maybe you could also try a taller tire. I run 255/85/16in. on my F250 w/3.73 and turn about 2750 rpm's @ 60mph.

Pretty specialized my understanding. Because it is a DANA you can look outside of Ford for ratios.

I think I have the same size tires and I know the rims are 16 in.

Axle ratios available 1966/79 F250 Dana 60: 3.54-1 / 3.73-1 / 4.10-1 / 4.56-1.
In 1980, Ford introduced 3.07-1 & 3.23.1 in Dana 60's. Ring & pinions in these two ratios, and 3.54-1 are very hard to find.

The rear axle is a Dana 60...there were no 302 engines factory installed in F250's until 1980.

What would be the rear end in a 1990 F250 4X4?
What would be the possible ratios?
And
What would be the rear end of a 1991 F350 4X4?
RATIOS?
These two are up on the auction block in another office of the company I work for.
Thanks again.

Bummer
Too bad. I'm sure they won't easily mate up to my 72 either. How do they compare to a Dana 60?
