Ray,

Sounds like you have a New Process 435(NP-435)

This is a heavy duty 4-speed tranny. I mean "Heavy" in more ways than one!!

Take care,

Thanks Lee,

What sould I use for lube oil?
I noticed two filler bolts, one high and one low.
I really like this tranny, the granny gear is super low though.
Any advice on care and maintenance?
Thanks, Ray.

No problem,

These were a VERY popular tranny. Rebuild kits are still avaliable also. Best part is that no special tools are needed to rebuild it. Somewhere I have a rebuild procedure and it calls out for tools like: Hammer and wood block. My kind of tools!!

I am away on business right now so I can't answer you oil question. I have my book at home. If I am not mistaken I used 80-W90 in mine.

These are a tough tranny used by all of the "Big 3" automakers at one time or another. These are the ratio's off the top of my head so don't hold me to it.
1st 6.64:1
2nd 3.34:1
3rd 1.74:1
4th 1.0:1
Reverse 8.375:1

Take care,

Reverse had a higher ratio than the granny gear?

Gtex,

Yes, that is what my research shows. I just did a search here at Ford-truck and found an old post that stated the reverse ratio as 8.02:1

Take care,
