NP 435 identification

I've got an NP 435 out of an 87 F-? I'm trying to figure out if I have the good gearing (6.69:1), cause if I understand it right there were 3 different gears available...the serial number as good as I could tell are:

G-13894
FF(?) 2 9 3386
c11240 (on the top cover)

Any info would be greatly appreciated...

If the transmission came out of 87 then its not a NP-435 if it came out of a 78 then it maybe. A NP-435 usually has a aluminum shift tower the T-18 has a cast iron top. The T-18 has a prominant bulge on one side and its shaped differently.

If you had a pic I could tell you if its a 435 as for the gear ratios I couldn't tell you. The 435 does have a slightly lower first gear over the T-18 BW. As for the transmission choice I would take it would be a T-18 its nicer to shift the gear ratios are better.

I have driven old 70s trucks with 435 and a 80 truck with T-18 I prefered the 18 especially behind the weak 351m that powered my F-350.

Everything I've read so far, says that they came in F-150's and others until the early 90's. It's defenitely an NP 435 w/ the aluminum top. My factory 87 service manual shows dis/re-assembly as well. I think dodge ran them until 93 or so. I just want to know what the gearing is on it

Thanks for the reply though

The 435, T18 and T19 were offered into the early 90's, they just aren't that common.

Anyhow, all Ford NP435's have the 6.69:1 first gear and wide ratio gearset.
