C4 not fitting my transfer case? HELP BRONCO GODS!

[Leroys Bronco]

Hi Bronco Bro's,

I have a 1968 Bronco with a stick shift, and purchases a complete C4 from a another bronco, so the transmission is installed BUT am having a problem, that with shaft and gears off the stick to go on the C4 that mates to the transfer case HELP!!!

In side the transfer case that accepts the original gear set from my original Stick shift transmission and does not mate to my C4 that I can see??

My original STICK shift transmission with the gear sets factory installed that has a different shaft then my C4?

My C4 Transmission already installed in my bronco and ready, but how do I install the gears set from the stick to the C4?

Please any help would be great I am COMPLETELY stuck

Thanks for all your guys help!

okay, what's going on? is the t-case input shaft bottoming out in the C-4 before they come together? i see something in the side of the opening of the t-case, what is that?

i have a automatic transfer case if you need it. it'll just bolt right in.


BTW, i'm a mobile mechanic, i can come to your location if you need help.

just looked at your pics again. if you're going to re-use your t-case, you'll need to take the cluster gear off the manual tranny, then take the bearing and shaft out. here's the fun part; you'll need to cut 3/8" off the input side of the shaft you take out.

The stickshift shaft that holds the gears on as seen in the picture is different then the automatic shaft that is comming out that is already installed in the bronco as pictured?

Thanks for the Help Leroy

The C4 transfer case adapter uses a diffent out put shaft. It will have a big casing that does in and seals the back of the trans so the oils stay seperate. You can't reuse any of the parts from the manual setup. Alot of people don't realize the C4 part comes out of the transfer case and is part of the adapter.

I guess I'm just slow, because this thread has confused me. If he has A) a C4 from an EB, and B) a D20 from an EB (originally installed with a 3 spd), does he have all the transmission/xfer case parts needed for the conversion? Forget about tans cooler, starter, flexplate...I'm talking the drivetrain parts. I thought the answer was "yes", but I'm not sure anymore after reading this thread. I always had it in my mind that the D20 would bolt up to either the 3 spd or the C4. Of course, my mind isn't what it used to be! :'(

 

[Leroys Bronco]

The problem I am having is that the automatic shaft that (I GUESS) would hold the manual gears that bolt up to the transfer case is NOT long enough, The manual transmission shaft that holds the gears is LONGER ? So what do I do, still DAZED AND CONFUSED.

Please help oh Bronco gods! :'(

The extra part for the auto setup is the bearing retainer hub. When I pulled a replacement t-case off a C-4 it looked alien to me. You have to pop the hub out for the case to mount to the manual tranny. In your case you need the hub. It has the t-case gears on one side and the splined input fot the auto on the other. It is pressed into the t-case. The purpose for this as previously stated is to keep ATF and gear oil seperate. As for haveing the correct adapter I have no idea. Someone else will know though. Good luck.

Just did this swap the other day

I have '68 Bronco that I did this swap on recently.

Look at the pic of the T-case above, when the manual three speed was seperated, with the adapter, it left a hole in the T-case. When you want to swap to the C4, the original T-case connected to the C4 needs to look just like the T-case picture above, there should be a hole in the case. The C4 adapter does not connect to the input shaft of the T-case connected to it. It is basically a hollow tube with a breather and it holds ATF. The input shaft on the C4 T-case is only held in by an O-ring, so it can be pulled right out. It will slide right in to a T-case that has just had the 3 speed manual trans adapter removed.

It looks as though you need to return to the place of purchase and pull the remaining parts (input shaft and gear) out of the original T-case that was attached to that C4.

The transfer cases are the same, but the transmission length differences are made up w/ the intermediate housing. He is missing the bearing retainer and spud shaft for the auto. My first swap went the same way and the guy wouldn't give me the retainer cause it looked like it was part of the transfer case. I reached over and yanked it out and showed him I was right. I have an extra at home if you need a pic, I couldn't find one on the net, but mine isn't for sale. The last swap i did took a little working w/ a rubber hammer to get the retainer out.

leroy, i have a transfer case i don't need that will bolt right in with no mods needed. if needed i can just toss it in my car and drive it up to you.

Well, I'm not confused anymore! Hope the same goes for you Leroy -- by the way..'73 -- if I were anywhere near you, you'd already be at my place!!

Ok,
We are getting close, I got the SPUD SHAFT, bearing and gear set off the stick trans, now and I understand how it takes up the gap and fits

But the SPUD SHAFT outer bearing fits tight against the stick trans while
when installing in the auto transmission the outer part of the bearing has no place to hold it tight big GAP is there a retainer I am missing and sticks out farther then it should. There is also a seal inside the stick trans adapter while the is no seal inside the aut trans adapter,

Hey I left a message for ya on that auto transfer case and your steering column is SWEET, want to know about that to.

Thanks guys Leroy STUCK IN BRONCO CONVERSION HELL

The stick shaft is not usable, you have to get the auto parts. The intermidiate housings and guts are completely different. I'm looking for the pics.

Leroy, do you have what you need?

So the hub that sticks out of the transfer case is part of the C4 conversion?
How are you supposed to press it out? Do you have to remove the output shaft on the other side and push from the backside?

It is just slide in but has an oring on it and can be a bear. I have both used a rubber hammer and tapped/worked it out, and also remove the output shaft and tapped it out. I have also had it just pull right out. As with all, there are the 13 needle bearings that may dislodge while removing.
