I'm not going to ask how much, or how to, I already know the answer to that. I do have two other questions though.

My FIL's '98 F250 LD (F150 on a heavy frame and 7 lug) has a slipping 4R70W again. last time I did a filter and drain & fill X4 pumping from the cooler line. Its been working great for about a year, but it slipped yesterday. He is going to get another truck and asked if I want the F250.
What I want to do is go to the wrecking yard and get a manual trans, flywheel, clutch, starter, pedal assy, etc to swap in.

1.
Does anyone know what trans bolts behind the Ford Modular OHC V8 (4.6 i think)? I would like to swap in a transfer case at the same time for another phase of the modifications. If anyone knows what transmission/transfer case/truck models to keep an eye out for I would surely appreciate it. The more HD the better.

2.
Keeping in mind that the slushbox is dead and I want to swap in a manual, what experiment/remedy would you all rather see or expect to have the better chance of helping limp it along awhile.

A. Universal tractor fluid

B. Type F

C. Other cheap non-approved fluids

I am not interested in additives.

You'll have to take the PCM from the truck you swapped from, OR have the original PCM reprogrammed or it will be very confused why there is no transmission. It'll probably rev-limit you to 3 or 4k rpm as that is usually what the 'neutral' limiter is at with an auto.
 
Try the lubeguard shudder fix. It stops slipps too. Its approved by ford, so its really an OEM fluid.

Behind a 4.6 you could install any manual that bolts up. Just look up on car-part what manual came in the 4x4s and get one of those. And a trans cross member, and make sure the xfer case will bolt to that...

If the truck isn't free it may pay to drop another 4r70 in there or find a 4r100, sell it, and buy a manual truck.
Finding a manual truck in the yard is like finding Hens teeth.
 
Last time it was slipping on the 3-4 shift and going to red line if you pushed it.

according to Wiki all the Modular engines share the same bell housing pattern.

Anyone have a ZF and like it?
 
1. Don't try to do some one-off custom manual swap; not worth the time or financial investment.

2. First, do a complete fluid replacement with ATF+4. Report back with the results.

3. Secondly, if you want to replace the transmission with something different, swap in a 4R100.

No
 
Ok, I get it now -- this is like the guy the other day that wanted to custom fab a unicorn trailer.

You're wasting our time, and yours with the pie in the sky dream thread here that has 0% of becoming reality.
 
It's not a one off, it's a conversion using wrecking yard parts. In case you are not aware the same truck was available with a manual. I did not ask your opinion or what YOU are capable of. have a nice day and please find yourself out of my thread.

Where did I say 5.4? It has a 4.6 and according to the chart YOU posted it was available with a 4.6 and manual. And at any rate the 5.4 and 4.6 have the same bolt pattern, so it would'nt matter anyway.

Swapping auto to manual, or manual to auto is not difficult. Not sure why you think it is?

Actually, according to YOUR chart, the 5speed is standard, while auto is optional. Wierd.

Did I mention I want a transfer case? because I was thinking about a Corporate 14 bolt and a Dana 44 for the 8 lug pattern (and added HD).

Its all completely doable, granted the front tend would require some steel and some welding.

Not really interested in additives, but interested in experimenting with fluid for grins & giggles.

Its not currently 4x4. a divorced NP205 is not out of the question either.

It would be a free truck that isn't worth a hill of beans.

Plus I love people that basically know the answer to their problem, we address it and they just deflect, resist, refuse any logic offered from experienced people on this forum...

Do as you will...
But why F'n bother with asking us then...

I didn't ask the questions to his answers.

I asked

1.
What models should I look for?

2.
What fluids would you like to see me experiment with in the meantime.

There would be no hostility if people stuck to the topic and didn't inject irrelevant opinions.

I guess if i get the truck I'll just join Pirate 4x4 where people get it.

By the way... I completely understand what you are doing, and the availabilty of parts... I just see more issues than it's worth - unless your donor is found for basically free or to swap over parts from a vehicle you will spend more than the whole outfit is worth to do it...
Again, not our problem.. we are just advising you it is not a wise decision for what it entails time and money wise with the information given. Just don't be frustrated with us with the advice...


Your monkey, your circus...

I have seen folks on the internet get the whole pile of parts from a wrecking yard for $150, so I think it could be cost effective, and certainly cheaper than a rebuilt replacement auto.

I don't mean to criticize anyone's advice, but people should realize that some people are capable and willing to do the work while being be frugal.
 
That being said and as a hobby for S and giggles... Sure. I can see and even appreciate that...
Unfortunately, to many folks on here ask a question like that thinking they can SAVE MONEY or save the earth refabbing an ol' dog like that and do not understand the issues at hand or have the ability (financial or mechanical or time, for that matter) to pull off such things. That is just what we are trying to prevent.
But for you - wrench on my friend !!

I love the ZF-5 that came in the F250 and F350s of that era.
