Looking for the ZF 5 transmission from the small block 4X4 donor. Anyone have one available.

Thanks
Dave

FYI i need it to bolt to a small block with an atlas 2sp coming off of the rear. I wont have the Dana 20 bolted to it.

Thanks JGZ, how much for the adapter. You can PM me if you like

I think the ZF bolts directly to the Atlas, but needs a spacer (it does to the 4 speed Atlas). I have a 1" spacer that I didn't use. I went to a 1/2" spacer just to get as much space as possible due to the length of the 4 speed. If you want the 1" spacer let me know. It's been mocked up but never run, minor scratches from test fitting.

Thanks for the input and info. I will get my tranny first then cross the adapter bridge as well.

Yes, the ZF5 does bolt straight to the Atlas. It does require a spacer, but I went the simple route and shortened the output shaft by 1/2".

It was suggested I do that, but it didn't work for me. It seemed the ZF output shaft splines weren't 'long' enough and caused the interference. Maybe I was alright, but I couldn't push the Atlas and ZF flush together, and I was afraid of using bolts to take up the gap, less than 1/8". AA said it would damage the Atlas.

I believe that was a good move on your part by not forcing it. What vehicle did the transmission come from.

I'm not exactly sure what it came from bought it from Craigslist ad. It has a 1989 date code if I remember. From what I've read most came in F250s, but some were in F150s.

I have another ZF I found since but haven't test fit or measured the output shaft/splines to compare. I don't remember the date code from that one.

As best I know late 80's to mid 90's F250 that had a 351W, my master cylinder is from a '95 F250. I will take a look and see if I can find my info from when I did the swap. I would be careful with the F150, thought they came with a M50D.

Just look at the tag on the driver's side of the transmission. It will have a ZF and Ford logo and right below that, a P/N. You want the S5-42 or S5-47

I donΓÇÖt think any small block zfΓÇÖs were anything other than s5-42ΓÇÖs were there? I think the 47ΓÇÖs were behind diesels for the most part but maybe I am mistaken.

The last twoΓÇÖish years there were S5-47s behind Windsor small blocks, but only the larger 3/4 or 1 ton. Mine was pulled from a ΓÇÿ97-98 F350 crew cab 4x4.

Mine is from a 97 f-250. It's the 47.
