If your truck is 2wd and you want to convert it, then you'll need a transmission from a 4wd truck. You also can run a divorced transfer case but that might end up being more work than it's worth.

Those directions are good, but they're meant for the M5OD. The shifter comes off a little differently on the T18. I think you have to remove a cap and under it there is a small roll pin you have to take out to get the shifter out. Also since the slave is external you don't need to disconnect the line from it.

To change the fluid there are two plugs in the passenger side of the case. Remove them both and let all the fluid drain out, then replace the lower one and fill it back up to the hole. Use 80w90 gear oil. You don't have a torque converter.

 

If I just pull a tranny out of a 4x4 bronco along with the transfer case I can install them both and run my truck no problem without a front end suspension right?

Which engines have tranny's that will bolt right into my truck?

Thanks for the help.

 

Yes you can but I would take one out of a pickup instead. Here's why: All Broncos came with slip yoke transfer cases. The front of the driveshaft slides in and out of the transfer case when the suspension flexes. This design is weaker than the fixed yoke transfer cases found in pickup trucks. With the trucks, there is a slip joint built into the driveshaft that serves that purpose.

Depending on your truck's wheelbase you may or may not have a carrier bearing with a two piece driveshaft and you may or may not need one when you're converting it to 4wd. Post the details about your truck - reg or super cab, ext or short bed.

So once you figure out the particulars of your rear driveshaft, you will need to have yours or a junkyard's cut to the right length.

There really is a lot to a 4x4 conversion project, and as you can see, there is a lot of planning that needs to be done. Then you need to do your research to make sure what you're planning to do will actually work.

In the meantime, if you want to stick to the four speed manual, all the clutch kits are interchangeable. Five speed transmissions have a different input shaft spline count so you would need a different clutch kit if you decide to go that route. Obviously if you decide on an automatic there are a lot of things that need to change.

I would also suggest thinking about upgrading to an 11" clutch. It will bolt right into place of your factory 10" setup and you'll get a lot more gripping power.

 

Well I'm goin to do the 4x4 swap Within the next year. Actually, just before the truck started slipping a week ago I was already doing research and getting my parts list ready to do an asa swap.

With all of this that has happened I think I'm just going to get started on the swap. Im starting off with a zf out of a f250/350 equipped with a 300/302/351w (any tranny from these trucks with these engines will bolt right up). The Asa will have to wait a couple months before I can break the news to the wife That iNEED to get an ASA hahaha...

So just to clarify pulling a tranny from one of these bigger trucks along with a transfer case will not be a problem, my question is since I will not be doing the Asa install right away will it run ok with the 2wd front end and will there be any fitment issues?

 

Migs where you at? Fill out your stuff------------------------------------------------------------------------^

Cool video, sounded and acted like the clutch was slipping like you said.

x2 everything Andy sez about anything. (especially in post #21)
He's careful and makes corrections when needed. :)

"4 TOD" has plumb got on my nerves. LOL :)
Have you got a T18 or what?

Notice how the butt-end tapers up on the case?

A T18 has an all cast iron case and lid...

A T18 doesn't have overdrive (OD).

When you get ready for your ZF swap start a new thread, please. LOL :)

To get you ready for how cool it's going to look...

ps- SideWinder, the EGR recirculates exhaust gas back into the cylinders,
the thermactor pumps only fresh air into the exhaust pipe and/or exhaust
manifold. ...into the manifold while the engine is cold and after/behind the
oxygen sensor after it warms up. Learned that stuff here on FTE. ;)

 

Well I have no idea what tranmission it is, that's the only thing I have heard it called on other forums. The sticker near the locking mechanism on the driver side has a code B On it and here are some pics maybe you can help me identify it.

 

I really don't all that much since I've mostly concentrated on
what my vehicles have, but...

That ain't no T18! LOL :)

And it ain't no ZF neither...

What of it being a T19 instead?

 

So then we agree... 4 Speed TOD it is haha...

 

But you also said it has a granny gear which would make it a T-18. The T-18 and T-19 look very much the same externally, and that thing looks like neither and it's not even close. So we can rule both out. It could be an NP435 but I'm starting to think you have overdrive and not a granny gear so it may very well be the TOD.

What's an ASA swap? Do you mean SAS (solid axle swap)?

The transfer case and transmission will bolt up but you will have driveline issues. Running a transfer case with a 2wd front end is fine. See my post above for details. For some reason I think you skipped it.

 

I think that's an aluminum case so it's got to be a TOD. But if you're swapping it out it doesn't matter much.

 

I usually respond with my phone which loves to auto correct, but yes I was referring to a solid axel swap (sas). I apologize...

It does have over drive and I guess I said granny low because 1st gear in that thing is horrible! 10 mph and I'm having to shift to 2nd...

What kind of driveline issues will I have swapping a tranny with a transfer case?

 

See post #33.

 

Thats where I have to shift with my M5OD....Just saying...

 

Take a picture of where they come together.
...got a camera to use this time around? ;)
