Hi All,
Been going through various parts of the forum, trying to establish if the 67-72 F trucks that utilised BOTH the Warner Gear T98/T18 and also the New Process NP435 manual 4 speed transmissions were interchangeable at THE BELLHOUSING FACE?

I am asking particularly about 240/300 in-line sixes (which I am led to believe shared the same ENGINE to BELLHOUSING face pattern as the 302 Windsor)) instillation. Naturally, whatever transmission that bolts to this particular in-line will have the same engine to bellhousing face fit up, BUT would the REAR face of the bellhousings differ between the Front face of the Warner T98/T18 and the NP435?

Simply put, can the two transmissions be swapped for each other? Forget length for a moment, one is supposed to be an inch longer than the other.
I would imagine that input spline counts, spline diameters as well as input spline lengths WOULD be identical so as to cut down on production costs.
Can find plenty of references to the inline 6 240/300, likewise the NP435 and the Warner Gear T98/T18/19, but NOWHERE can I find if the same BELLHOUSING was used for both transmissions.

I have a couple of Ford NP435's here, plus a Dodge NP435 (different input spline set up, as well as different transmission face pattern) stashed down at a mates place waiting to get a chance to lift it out.

Got a project in the wind that calls for a Ford Warner Gear T98/T18/19 transmission if I can find one, (they are about, but nowhere near as common as the NP435 at least over here in Australia). IF they use the same bellhousing, I may be able to cheat a bit and use an NP box with an adapter plate.

Would certainly appreciate any thoughts offered, perhaps someone who has access to a master parts catalogue could look up the listings and either pass them along or post them in a reply?

Thanks, Dave 64

 

Yes. They are Dave,
Part number for the bellhousing in my micro-fische says D1TZ6392D. Stamped D1TA6394BA. It fit the following with a 240 or 300 L.D.
65/66 F100/250 (4X2, 3 or 4/M/T).
65/72 E100/300 (3 or 4/M/T).
66 F100 (4X4).
67/72 F100/350 (3 or 4/M/T).
I did not check for part number replcements.

 

Jeffafa,

Thanks for the reply! Much appreciated. Cheers

Jeffafa,

Bear with me a minute, please. I have tried to decipher the part numbers and if I have it right, should look something like this?

Number/letters stamped on bellhousing are as follows:-
C5TA-6394 7

C-(decade, i.e.1960)
5- (year within decade, i.e. 1965)
T- (Truck)
A- (light truck engineering division).

6394 is actual part number,
7 (revision, if applicable?).

Now, the numbers you quoted, firstly:- D1TZ6392 D, if I punch that in, the computer is telling me the part belongs to a 1965 model Ford truck.

If I enter the second number you quoted, D1TA6394 BA it comes up as 1976 model Ford truck.

So, (bear with me please), does this mean that the two bellhousing numbers relate to different transmissions? I.E. Maybe one belongs to NP435. (D1TZ6392 D)

The other is for the Warner gear transmission (D1TA6394 BA?).

Or is it simply that the actual PART NUMBER has been updated?
I simply wish to be absolutely sure that the two transmissions (NP435 & Warner T98/T18/19) CAN be bolted to the SAME bellhousing. Otherwise it COULD be a costly error on my part. It would be a P.I.T.A to order bits and pieces especially from the States and then find that the two part numbers (the 6392 and the 6394) relate to two entirely different bellhousings and I'm left to trying to source the correct one.

I do not know enough about the actual applications of each transmission as to where and when they were used, other than reading what forum members have advised. The only thing I can add is that it seems that the early Ford truck manuals (over here) were predominately NP435 and I only arrive at that conclusion by reading as many posts as I can, and a few phone calls to transmission rebuilders in Oz. Not really all that convincing, again one guy told me that we NEVER got any F trucks here with Warner gearboxes (I think that's B.S!), one other told me that he "thought" that they were one and the same box, yet another reported that the only deep first gear transmission was an NP, only one was honest enough to actually say that he hadn't a clue!

So, simply going by the popularity of these early girl F trucks over your way, I think I'd be better off listening to you guy's opinions!

Sorry if that's a bit long winded, just want to make sure!

Cheers, Dave 64

 

US/Canada: No Warner T-98's were installed after 1964 // Ford 3.03 3 speed - Warner T-85N 3 speed O/D (1965/71 F100 2WD) - Warner T-18 - New Process 435 use this same bell housing:

D1TZ-6392-D (replaced C5TZ-6392-A) .. 240/300 Bell Housing / Marked with ID engineering number: D1TA-6394-BA or C5TA-6394-A

1965/66 F100/250 2WD 3/4 M/T / 1965/79 Econoline 3 M/T / 1966 F100 4WD 3/4 M/T / 1967/79 F100/350 3/4 M/T

JEFFFAFA is using microfiche, cannot post pics, but I can...because I'm not using microfiche.

6392 is the basic part number for the bell housing =

 

Bill,
Thanks! Your second line is good enough for me!

" Warner T-18 - New Process 435 use this same bell housing:

D1TZ-6392-D (replaced C5TZ-6392-A) .. 240/300 Bell Housing / Marked with ID engineering number: D1TA-6394-BA or C5TA-6394-A"

You blokes have all been a great help and it has been appreciated!

Cheers, Dave 64

 

will one or both of these bolt up to a 1965 F100 240/300 with a 3.03 M/T
C5TA-6394-A
D1TA-6394-AA

Thanks ,
John

 

Both will, see your other thread in the 1961/66 forum.
