Ford F834 Posted July 14, 2020 Share Posted July 14, 2020 Jonathan - I have the two DN documents on the page at Documentation/Driveline/Transmissions/Over-Under Drive and the Doug Nash and then DNE2 tabs. However, it appears there are pages missing in the Manual. Looks like pages 2 & 5 are missing - unless the last page is one of them. Scott - I don't want to host something that shouldn't be out there. What do you think about contacting GVOD, giving them a link, and asking if we can put it there? As for notifying people, I wish! Maybe after we get a copy of Nabble running on our own server we can figure that out? Hi Gary, the email in my “sent” folder has page 5. It has info for C6 installation and speedometer information. If this did not come through I will gladly send it again. As for page 2, I’m not sure. The “first” page of the manual has no number on it, and the installation manual has two page 1’s. I saved these images from a forum post on another diesel group. They are in the order that the poster had them. Perhaps the manual had a blank inner cover or??? Anyway, let me know if you need me to resend page 5. I am going to keep my eye out for a better copy as well, since I own one of these. Link to comment Share on other sites More sharing options...

For whatever reason I had the page that apparently was Pg 5 as the last page, but I've put it in what is apparently its proper place now. But Pg 2 still seems conspicuous by its absence. As for the quality, it is better than nothing but not really "good". Is Doug Nash Enterprises still in business? I didn't find them in a search, nor did I find an owners manual. Maybe we have what there is? Link to comment Share on other sites More sharing options...

My understanding is that the seals and bearings are common GM transmission parts which are not too hard to match up if you have the original for reference. They are not completely obsolete white elephants, but are not still supported like Gear Vendors. Being a direct gear drive design with no wearable clutch they are heavy duty and tend to last a long time. You are absolutely right. These pages are better than nothing, but certainly not great 😕 Link to comment Share on other sites More sharing options...

The unit seems pretty straightforward, but like every inch of my truck, theres wires everywhere. I will start from scratch. Im not really sure how Id like to use it. Im not to sure of the gear splitting because my trans slips a little between gears right now. Would that mean I get more slipping because its shifting more frequently? Im putting new fluid in this weekend so We'll see how much that helps. But if I could get a higher overdrive for my short highway commute, Id be happy. Honestly, this is not something Id buy because I really dont have much need for it, but the PO installed it and Im slowly trying to track down all the wires in this truck. So this project is part of a longer journey. Link to comment Share on other sites More sharing options...

So this project is part of a longer journey. If you travel over 45 mph for any distance at all I think you'll be pleasantly surprised. With the 460 don't really expect to see a mpg difference on a short commute but the noise level alone (rpm) to me is worth it (maybe not full price worth it but it really is nice). I don't believe this would impact the transmission slippage since it would still be in the same gears as the gvod is after the transmission (and tcase). Personally, I'd stick with just leaving it in Auto mode (overdrive) and play with the splitting when you get more used to it. If you want you to just try it out you can bypass the brain box and manually engage/disengage it. It all comes down to energizing a solenoid. The brain just controls the automatic portion of it and the safety features. If you do so, just make sure you follow the same precautions to avoid running it with low pressure. You likely found this already but in 4x4 trucks it now calls for Lucas 75w-90 gear oil. They've changed their recommendation over the years and I think mine had automatic transmission fluid in it when I got it. The only thing I can think of on rewiring it is that they don't want 'power on crank' going to it. I hooked mine to the heater wire under the dash. Gary - sorry I never responded. I mailed this out the other day. It's composed of single sheets with a staple in the middle. Feel free to cut them in half if that's easier and you have a slicer.

Scott - Are you SURE it is ok to cut in half? I hate to do that, but.... I do have a paper cutter, so that would be easy. And it is a royal pain to scan each piece of paper, duplicate all of them, re-order them as the bottom half are now in reverse order, and then crop each page to get the right image. But you said it is something like 44 pages. That's only 22 pieces of paper so isn't too bad. It was that 200+ page owner guide that tested my religion. So I can get there by not cutting them. Your call. Link to comment Share on other sites More sharing options...
