67' 240 cid 6 --3 speed to 4 speed trans. Question

[j4acub]

Fellows, I have a 67' 6 cylinder 240 cid. F100 with the Ford light duty 3 speed transmission, column shift. I want to convert to a 4 speed trans with a floor shift. Does Ford have a 4 speed trans that will plug right in with no modifications, expect for cutting a hole in the tunnel for the shift lever.
Thanks, Tim

From what I've been able to decipher, the T18, T19 and NP435 are all candidates with their various strengths and weaknesses. Here's some technical data on these. http://www.novak-adapt.com/knowledge/np435.htm and http://www.novak-adapt.com/knowledge/t18_t19.htm Here's a discussion regarding the pros and cons on the FordSix forum https://fordsix.com/forum/viewtopic.php?p=381054 A quick search on Ebay turns up a bunch of these transmissions in early '70 - late '80 Ford trucks in 2WD and 4WD configurations. Maybe somebody with more experience will chime in. I'm just going by random searching and reading other's stuff.

A lot of information there. I guess it won't be as easy as I'd hoped.

That's not to there's not a straight bolt in, just that the possibility of one exists but will require extensive research to choose the right one, then find one. I believe you stand a good chance of finding a 4spd tyranny that will bolt to your engine however, you will most likely need a different drive shaft. I'd give Nova a call and ask them which of their 4spds would bolt up and get a price quote. Then locate a used one of the same variety.

Your not kidding about that. It's made it doubly confusing due to the fact I know just about zero regarding bell housing, clutches and the different transmission gear ratios.
I looked at the Nova site and it seems they are Chevy guys, or am I missing something.

This is an interesting discussion. I called Novak and, basically, they don't do Ford-Ford. However, they do Jeep to Ford and Ford to Jeep. The tech guy told me the T18, T19 and NP435 all use the same "butterfly" pattern on the transmission to bellhousing side, 6-1/4" L/R and 8-1/2" Top/Bott, c-c of the bolt holes. From what I've been able to find, the bellhousing to engine side of the equation is fairly interchangeable between the I6 (240 and 300 ci) and the small block V8. So, to sum up, you should be able to find a donor vehicle or transmission with a T18, T19 or NP435 4 spd transmission behind a small block (289, 302, 351w) or I6 and stand a pretty decent chance of having a match. I'd look for 2wd Ford trucks from 1964 through 1979 that have a floor shifter and a small block engine. Then measure the bolt holes where the tranny meets the bellhousing and look for 6-1/4 x 8-1/2 c-c. Sketch the bellhousing to engine block bolt hole pattern and check it against the donor vehicle, mostly just number of bolts and general locations. Also verify if it's a 2 bolt or 3 bolt starter, yours is probably a 2 bolt and you'll want one similar as that implies flywheel size and tooth count. If you find one, you have a pretty good chance it'll work in your truck.

If anybody else out there can confirm/refute this conversation, please speak up. I'm strictly going by what I'm reading and interpreting. Experience trumps research any day.

Just signing in to follow, as this is good info.

Check this out. The poster says he has a 67' F100 with a 4 speed transmission. He doesn't say if it is original equipment from the factory or if someone else put it in before he got it. I've looked at lots of sites on 67' Ford F100 specification but have yet to find one that say what type of transmission were standard equipment or if there were optional transmissions available. Maybe he will read this, I hope.

Does anyone know if a 67' Ford f100 240 cid six cylinder was offered with a 4 speed transmission as an option. I should have asked this question at the beginning.

According to the VIN plate code options http://www.fordification.com/tech/VIN67.htm the T18 and NP435 were the 4 spd options for 1967.

Wow, this is really embarrassing.

[sargentrs]

Don't be. I've asked dumber questions.

If you use a transmission that was available in Ford Pick-up trucks between 1965-79, I would say that the biggest differences you'll run into would be with the length of the transmission cases/tailhousings, whether or not you will have to move the transmission crossmember backward or forward and the number of bolt holes where the trans bolts to the bellhousing. Some transmissions may have 8 holes while others may only have 4 holes. You may be able to drill the extra four bolt holes if you need them. Also some trannies have a fixed yoke while others use a slip yoke for the driveshaft. Then, of course, there's the length of the driveshaft itself.

With many transmissions you can still use your clutch linkage, bellhousing, clutch disc and pressure plate. I would say that the chances are very good that you should be able to. Most input shafts were 1 1/16" diameter with 10 splines, except for some trannies that were used with Big Block V-8's. It would be a good idea to compare the length of the input shafts, but I believe the 1 1/16" shafts are all the same length. Off hand, these are the things that come to mind. I Hope This Helps.

Another bit of information found on this site.

Borg-Warner T-18 4-speed
Another Granny-Gear transmission. These transmissions were installed in many 1965-1985 Ford pickups (as well as Jeeps and IH Scouts) as a successor to the T98. Ford used three different versions of this transmission, which is equipped with a 28-spline output shaft. Both the case and top cover are cast iron, with the top cover being secured with 6 bolts. First gear and reverse are not synchronized. It's replacement, the T-19, was used in '74-'88 Ford pickups and some IH trucks and is identical in appearance except has a 5.11:1 first gear ratio which is synchronized.
The T18 & T19 has a 1-1/16" diameter, ten-spline input shaft that has a stickout of 6-1/2" from the front face of the transmission. The pilot tip of the transmission measures .668". The front bearing retainer flange measures 4.850" and the bearing retainer tube is 1.432" in diameter. The front bolt pattern is the symmetrical Ford "butterfly" pattern; 8-1/2" wide by 6-5/16" tall. The input shaft length is 6-1/2". Checking these dimensions will verify that the transmission is a 1966 or newer model, precluding it from being the T98. The transmission can also be identified by its casting numbers cast into the driver's side of the case. T18s have casting number "13-01" and T19s have casting number "13-09". Case length is 11.875". Unlike the  NP435, the PTO port is on the driver's side.
From 1966 until 1978, many T18s used a T98 shifter assembly. 1979-newer T18s used a three-fork shift cover assembly that shifts reverse gear directly. Because of this, reverse location is on the opposite side of neutral than the earlier version (‘66 to ‘78). Earlier versions reverse gears shifts over and up - later versions shift over and down.

It would appear that the T18 transmission is what I should look for, and hopefully require the least modifications, I hope.
