Bronco Tranny and T-Case Info

[adrianspeeder]

With all the posts on what trannys are what, or "what do I have" I thought it would be a good idea to make a total list for the full size fords. Just now I wipped this up to start off, but will keep workin. Please post any corrections ya'll see so I can edit.

For the engine listings. I'll break the shared bell housing patterns in {}.

Heres my contribution



NP-435

What a clean NP-435 looks like from the passenger side
it has an Aluminum top cover that the Shifter actually comes out of.
It says NP on it above the PTO cover
It has a PTO cover
the shifter goes
1 3
2 4 R
6.69,3.34,1.79,1.00 are the ratios



SROD

An SROD (Single Rail Over Drive)
Trans Code B
Made by Tremec for Ford (T150FS, it has a Ford symbol on the side)
From a site that said that the Top shifter version was mostly in Ford broncos (so may/may not be correct)
3.01 1st, 1.78 2nd 1.00 3rd .79 4th and 3.01 Rev
or
3.25 1st, 1.92 2nd, 1.00 3rd, .78 4th and 3.25 Rev

It has the shifter behind the tranny
Is one of the only Ford trannys that you have to Push down to get into reverse (its brother the SR4 has to do that as well)


Pass side (tag and Fill/drain plug)

Drivers side... thats a Ford Symbol

Is made entirely of aluminum(case) and may be found with the T case adapter cracked (also aluminum)

To get rid of the crap and put a diamond in its place..
In order to swap in an NP-435 in an 80-83 Bronco with an SROD
Trans Code Boriginally You need
NP-435, T case adapter, Bellhousing for a Smallblock with 11" manual clutch, and the shifter for the 208/NP-435

End of story these are the only things you need to change.

You need a grinder and a Drill w/ 3/8" drill bit to do the only fabrication mod.
It involves the T case shifter, Bolt the NP shifter to the case with the big bolt. Take the SROD shifter link (12-14" long or so) and grind of the nub on it. Drill the hole that is just the right size for the nub on the NP shifter to go threw it.

TRANSFER CASE INFO WILL GO HERE

Great idea Adrian

especially when it figures as the most expensive single component in the Bronco/F-150. In most cases, the stock engine isn't worth as much to rebuild as the trannies can cost.

If DarkSide or the moderators go for it, I'd like to suggest we add pics of things like the remote filters, auxillary coolers, routing diagrams for the coolers, etc. Also maybe a write up on each tranny's filter change, torque converter drain plug, etc.

Another item would be a drain plug mod and the different aftermarket pans available. Shift kits that helped, shift kits that botched the tranny too.

Special mention about the electronic equipped trucks habit of the in-rad cooler loop sludging up and killing the electronic trannies.

That special retrofit TV brass bushing available from Ford, that for one dollar, could save your tranny;



Think of the carpel it would save us !

Great idea Adrian

I could only add a few things, and all from just what I 've seen. I know they at least put NP's in threw 84, since they had the splined knobs, and thats what mine had when I got it from the guy.

Can you throw a pic in of each after the Heading????

[81Bronk36]

I added 2 new pics I took yesterday.... Of the tag and of the Ford symbol in the case.

Ive been looking to do this to my Bronco for a while now. Am I correct that the 300 bellhousing is the same as the 351W bellhousing? I can get a complete donor truck for $150 w/ a 300 np435 combo in it. I want to make my truck move a bit faster than it is now.

Thanks,

Tony

[81Bronk36]

Yup they both are the same bolt pattern. Is the donor truck an 80-83 as well, cuz you have mechanical linkage in your 83 and your donor truck may not.

Using an NP-435 probably wont make your truck move faster, sure you can lift the front tires off the ground... but you gotta shift in 5 feet. I usually start in 2nd, so I only have to shift 3 times, works pretty good. The 435 is a very good tranny though. What do you have in there now???

[83bronco5.0]

The truck is an 81. I got a 351 C6 combo in my Bronco now. Its good and pretty tough, but I want a manual. I had an F150 a few years back almost identical to this one, just a long bed. A total POS but man did that thing RUN! Im pretty sure it was an 80 or so. I had the 300/NP435 combo in it. I could pull a house off its foundation, but it couldnt get out of its own way on the highway. I had to get rid of it because I had no gas tank (besides a 3 gallon under the hood), no interior besides one seat, no back brakes, F'ed up electrical system, and it was in total black primer. I do miss it.

[81Bronk36]

Well cool then, you should have all the parts to do it. keep in mind that the 2" tab that goes from the pedal to the 20" rod that goes threw the floor is no longer made anymore, so you will probably have to weld a bead in your oval shaped one(I never found one that wasnt) but a guy at a local pump/machine shop did it for free.

Adrianspeeder

no prob, I dont want to rush things either. Also can we get a compatability list for years and trannies?

[81Bronk36]

They all swap since every bronco either came with a 300,302,and 351, and all output shafts and t case mounts are the same.

Yeah, but you might get a tranny from a 460 or diesel for some reason. What would be the best way to determine bolt patterns, or how do you even measure them?

Adrianspeeder

[rune~kincaid]

so I can get any year ZF5 speed from a 351 f250 and it will bolt up? Thats the stuff I am talking about, just a little confused

WHy would they change them??? and how would it make it not bolt up if both ends are the same no matter what year as long as its a 200,250,300,302,351W and the other end is made to bolt to a ford t-case over the past 30 years??

Actually, I think that list should be 240/300, (late)289/302/351W/351C. As far as I know, the 170/200/250 was a different (and earlier) straight six family, with only four main bearings. I'm not very well informed on these engines, though, so I'm not sure as to which bellhousing they use. The 351C, for all that it is part of the 335-series engine family, is still a small block and uses the Windsor bolt pattern. The other 335-series engines (351M/400) use the 385-series (370/429/460) big-block bolt pattern, which has always looked to me like a stretched version of the Windsor pattern (by a couple of inches).

Pretty sure its the same but Ill test fit the bell. My 68 came with a 200 and now has a 250, so I know those are the same

Oh and the 2.3 I4 is the same as a 5.0. My buddy took the T-5 out of a Turbo Coupe (T-bird) and put it behind his Mustang with a 5.0

Nice, that's another one I wasn't aware of. Simplifies things just a smidge if so.
