240 6cyl t5 swap

[jwright1982]

So this is my first post I have been searching this site for a long time without being a member but I finally cant find answers to a few of my questions. Forgive me if this is long.

I own a 68 f100 with a 240 6cyl and a 3 speed on the column(Ran-G1) and a 3.70 rear this truck is completely original except for tires wheels and dual exhaust. I purchased it with 62,000 and it now has about 71,000 The engine runs great but I like to travel for car shows 100+ miles away. Being that I am turning 3000 to run 70 on the freeway I have to change something. I have a wc t-5 from a mustang(1352-199) which would give me a .68 overdrive verses my 1.00 currently. If I did my math correctly with a 29.3 diameter tire that would put me at 2020rpms at 70. Which would be perfect.

But here is my problem I have searched on here and other places for t5 swaps and I'm not finding a lot of info. Basically a lot of people saying why you shouldn't do this etc. But I know it works I just need more info I know the trans mount has to be moved back and that the driveshaft will probably have to be shortened. My question is do I keep the bell housing from the 3 speed or go to the 5 speed bell housing and if I do has anyone made a linkage to use the same clutch setup or did you go to cable setup. And did you use the original size clutch (Oh I'm making a remote shifter so that's not an issue). Any help from anyone who has completed this would be great. If I can I will try to document everything I do for anyone else looking to make the t5 swap. Thanks.

I understand that you already have the T-5,but I "think" you might be better off with the M5odr2 as it's a truck trans has a .8 OD and the clutch is hydraulic so easier to retrofit in a bump. The M5's gearing is 3.91/2.24/1.49/1/.8 the T5's is 3.35/1.99/1.33/1/.68 the M5's OD would put you at 2395@70mph that would put you in the happy spot for the 240 don't know how happy it would be at 2000rpm and be much more drive-able and still help your mileage and the 3.91 1st would be easier on your clutch and more user friendly in the real world
just some food for thought.

we did the swap using the complete trans setup from a 1991 f150 with a six cylinder. We also have a 240 and 3.70 gears , running 33" tires. Drives great. has plenty of low end and easy on the top. not sure on RPM at 70. I can help with pics and such if you want to go this way. We have somewhat of build thread on the "calling all prerunners" thread. It is not a difficult swap.

this one is in the "tech articles" under drive train.

as long as the T5 is setup for the cleveland-pattern bellhousing it should be fine.

I don't know jack about T5's but they came behind everything from 2.3's to 5.0's and lots of other stuff in between, so the bellhousing thing could have a lot of different permutations, starter location, flywheel, etc.

i can't tell ya why it won't work, but the M5 trans is real real easy. it uses the same rear mount, crossmember goes about 2" back and the hydraulic clutch is pretty simple to mount. I think i cut about 6" out of my driveshaft but obviously you'll want to do your own measurement and all that anyhow.


also, it won't hurt that 240 to rev 3000 rpm all day long, but the 2000~ rpm is much more comfortable.

Modern driveline makes an adapter to bolt the t5 to your stock bellhousing.

I actually just got off the phone with modern driveline. I found out it is a direct bolt in with the t5 bell housing and clutch to the 240 flywheel. The only things needed are a cable kit which is 259 from them or some homemade engineering and mount the mustang cable to the original pedal. Shorten the driveshaft and modify the shifter.

There is a dude that has a website. Hes a fabricator that if you send him ure pedals he will retrofit the clutch pedal to work with a t5. Its mikes mustangs or something.

So what happened here? did you make the swap?

Ran into a problem with my T-5 (cracked 2nd gear) so at the moment I am hold looking for a new gear, slider, and clips to rebuild it. But I found a gentlemen in my area who has done the same swap and passed on some good info to get it done. As soon as I get new parts I will start the install and take pictures as I go for anyone that wants them. The guy I found let me drive his truck and it drives great he is running a few mods on his truck and is still getting 20 mpg.

I would definitely be interested in any info you can pass this way. I do have aT5 experience. When you say cracked gear . . teeth chipped off? 2nd and 3rd are teh most common and usually take out the counter gear as well.

Just to clarify on Timmytim's post, the guy he is referring to is mustangsteve.com. He mostly does mustangs, but he also does some Ford trucks. He can modify your pedals and put roller bearing for smother operation.

Please keep us updated on your T5 swap, I actually just bought a T5 today! Only to read everyone saying to go w/ a M5 swap. The only difference in my swap is Im going 5.0. I'm very curious what kind of shifter you need??

If you don't want to switch to a hydraulic clutch, the T5 is the swap.
