T18/19 vs NP435

[mjhaltom]

I pulled my T18 from a 1973 F250 with a FE and I have a 1971 F250 parts truck with a T18 and a 360.

OT, but can a T90 3 speed from say an early jeep or IH Scout be used in place of a T18 or 435? Just in case anyone might want a true floor shift 3 speed and not a 3.03 converted to floor shift.

[ima71 trucks are older]

Novak site says the T-90 has a 10 spine 1-1/8" input verses our ford 10 spline 1-1/16".

Wasn't the 3 speed in the early broncos floor shift?

I'd have to agree, it seems the NP435 is much more common. I'm not sure where cooltoolguys was manufactured but, FLATBEDFORDs F350, my F350, and the other '67 F350 we bought together, all where made in the Mahwah plant, and FLATBEDFORDs is the only one with the T18. Go figure. That's a pretty good question that I'd like to know the answer to also.
By the way, those trucks are the 4 he is refering to.

Count my F-350 in, My truck also has 360-NP435 combo as well, The vin in my truck is F35YLD*****. My truck was built in Michigan though.

My 70 1 ton has a t18 in it and my 68 250 has the NP in it. I know the 68 was work hard and thats my grandpa bought it new. It was all special ordered. My Dad said it would do a 100 mph easy. He told me that truck maked a 45 min drive up bigggg hills with 1500 lbs of bricks it the back and it was pulling a cab over ford dump truck that was loaded full with sand. And that was pulling a case back hoe on a flat bed, doing 60 all the way home.

T-18's are a lot more driver friendly if your used to shifting
without the clutch. Other than that, they could be sisters.

No, the Bronco 3 speed was the 303 and was always column shifted. Enterprising folks who like speed shifting (racing) came up with the floor relocation kits.

I have a 68 f-100 (built in kansas) that originally came with a 360/ t18 combo!!!! Just for reference!!!

My 65 was built in KC and it too has a t-18, behind a 240. I have wondered if some plants got one and others got the other.

Anyone have a NP in a truck built in KC?

My truck was built in Canada and shipped into the states, sold as a cab-chassis.

Sig tells the story

[averagef250]

All the 4x4's I've ever seen have had 435's. All the F-100 2wd's I've seen have had T-18's. The 250 and 350 2wd's seam like they could have been either way by the sound of what other guys have had, but I've always seen 435's. Most of the truck's I've owned have been canadian built.

Sort of a rough conclusion to draw, but from my experience the canadian bumps seam to have been built better than the US trucks. They sure seam to have less rust and interiors that hold up longer anyway.

[Ripsnorter]

So is there any real strength difference between the two? Or any real reason to choose one over the other?

My '68 CS was a special order, built in CA for delivery to Seattle.

It orginally came with a 360/Np435 combo.
The engine was either replaced or rebuilt as a 390...
I have a rebuilt Np435 to put in it when I pull the engine to fix the exhaust.
I used to have a '68 F100 which also had a 390/Np435 combo... I never had any problems with it...
The only problem I have had with the Np435 in my CS is that it whines...
it has gradually gotten worse over the past 20 years so I am gonna replace it.

Go with the one you like. I'm not a fan of the way the T-18 shifts or reverse being over and up or their tendancy when the top plate wears a bit to want to grab first going into third.

I've seen more 435's broken than T-18's, but I think that's directly due to the 435's being subjected to far worse abuse.

My 1968 f250 2x4 has a np435 and came with a 360. It now has a mild built 390 that dinoed at 405hp and just shy of 450ft lb torque, is now around 425hp and the np has held up great so far, burns the tires through all 4 gears and will brake them loose at over 50mph, so far a little over a year of speed shifting went well but it is starting to have a really hard time fast shifting into fourth now, I can no longer hit fourth while burning the tires through 3rd, synchros are probably hating life now, it jumped out of second once made a big bang but then kept driving, then had a knocking noise through the shifter, I stopped and it did it in neutral so I kept going to finish the cruise and after I shifted it went away but ever since that cruise its not wanted to speed shift 4th, sometimes it will, most the time it wont.

My 1970 f250 2x parts truck has a 360 and a t18 still not sure if I want to go through that or my np, I love the way the np shifts. I have a t18 in my
69 250 2x with a 240 I6 and hate how that one shifts
