And my question is, did Ford ever catalog it for the F-250 HD and the F-350 back in the 1983-87 period, which is all the years the 6.9L was available?Seen in the paper that a guy is parting out a 6.9 truck that has a 5 speed in it. What is it and is it worth useing?
Also, the NV4500; however the 6.9 was already bored to a 7.3, I believe, when this option showed up.6.9 had the 5 speed behind it last half or so of 1987 model year
The S5-42 was the first of these; there are two subvariants: wide-ratio and close-ratio. The wide-ratio version was available in the years 1987-97, while the close-ratio version was only available on the later 7.3 engines of 1994-97. The S5-42 was then replaced by the S5-47 for 1998.It is a ZF-5 transmission.
They come in two flavors, 2-wheel drive and 4-wheel drive, they can not be interchanged without an extreme amount of work. So you will need to get the correct version for your truck.
A change in number can mean many things or nothing. From what I have always heard only the close ratio was used with the diesel bell-house for the 6.9 and the non-ps 7.3s. You still need to know if it is 4x4 or 4x2.The S5-42 was the first of these; there are two subvariants: wide-ratio and close-ratio.
