Swap a 5 speed Transmission

Swap a 5 speed Transmission
I have a 1978 Ford F150 2wd with a 302 cid 4 speed manual transmission.
I found a 1992 Ford F150 2wd with a 302 EFI and has a 5 speed transmission.
What parts off the 1992 Ford 2wd must I take off to make the 5 speed transmission conversion possible?
Thanks for any input.

Okay, Bought the 5 speed manual transmission, clutch parts, flywheel, backing plate, and rear drive shaft off the 1992 Ford F150 2wd. For $175.00 dollars.
I going to attempt the possible and put this 5 speed transmission on my 1978 Ford F150 2wd.
Thanks in advance for any suggestions or comments

Grab the clutch master cylinder from the 92 as well. The flywheel from the 92 won't work in the 78 (unless it's not an original engine) as it's balanced differently. You might be able to bolt the 92 clutch onto your 78 flywheel, but you won't find out for sure until you try. You will have to modify your current clutch setup to switch to hydraulics to suit the M50D from the 92.
Good deal on the parts though!
Edit: https://www.ford-trucks.com/user_gal...&albumid=11298 has the best 73-79 hydraulic clutch conversion info that I've seen so far.

What do I need to do to make the speed o-meter cable function on the M5OD transmission?

Checking Runout
Do a search on your browser for this Lakewood Bellhousing - Installation ,Now I know this is not what you have I assume, but it will explain the whole process checking the runout and getting the center line of the input shaft and the center line of the crank as close as possible. I am here to tell you the first time you do it is a real SOB but after that, well it's still an SOB but you know what to expect. Good Luck

Putting in the clutch master can be tricky, I put a ZF 5spd in my 79F250 4x4 and that was the most difficult fab. I would recommend getting a T5 off a mustang 5.0 and you can bolt up to your 302, just adapt your linkage to fit the T5's bellhousing. Check out this site if you want to go with a T5, http://www.5spd.com There's more but thats all I can find in my "favorites" .. A 5spd will sure help with the Highway RPM and cut the cabin noise level.
Good luck with the swap, you'll love it.

Conclusion: The M5OD transmission is a one piece and I can't figure out how to check the run-out on the this transmission.

I don't know a whole lot about the transmission your trying to install, but I assume it's nothing high performance. I say lets not sweat the speedo right now until this project has a pulse once again and moves under it's own power. I dont believe the runnout will be an issue with this tranny. Hook it up and run it.
Good luck.
Good luck.

The site has changed sorry. Try this http://www.5speeds.com/cgi-bin/ikonboard.cgi?... This is exactly what my favorites section shows me . That gets me into a question and answer section with lots of 5spd info, unfortunately nothing on the M5OD. They were a Mazda trans and not known for strength. I had one in my first NEW truck an 89 F150 4.9 EFI and it worked well as long as I changed the fluid regularly. The second owner never bothered to change it at all and burned the synchros up within 80,000km/50,000 miles .
It was a nice easy shifting trans. but I never liked the Hydraulic clutch, hard to make a quick shift! Good luck with your swap.

No need to worry about run out as all ford parts are made with in specs that allow parts to be bolted to any other engine. Run out only needs to be checked when one is using an after market bell like a scatter shield or something.
The mazda trans had a speed-o cable hook up but in 92 this may have changed as ford went to the electronic speed-o which ran off of the tone wheel in the rear axle. My guess would be if ford did remove the speed-o hole it would have been left in the trans for a year or so.
The key to the HYD set up is to measure the distance of the mounting point of the HYD MC on the clutch pedal to the canter pivot point of the clutch pedal. This gives you the correct throw for the MC. I think I measured one at or around 2.75. I have a HYD pedal set from a Bronco and I could measure it again for ya. I have this pedal set up so I can perform this same mod on my 78 Bronco but it has a ZF.

Thanks for the site and info.
I have read on this FTE forum of M5OD problems
and seems to be related to not having the tranmissions serviced regularly and abuse. Anytime a person abuses and does not service their older stock transmission, no matter the make of transmission, the transmission it going to fail.
My Dad 1991 F150 4x4 w/5 speed M50D had over 345,000 miles on the original transmission. I worked a Ford Dealership and never saw very few M5OD transmission related problems. The M5OD transmission requires servicing and replacing of the Mercron/Dextron III fluid every 30,000 miles. Something alot of truck owners do not often and is overlooked when servicing their vehicle.
The M5OD swap went very smoothly. I plan on keeping my 1978 F150 302 c.i.d. engine original 2wd with 3.50:1 rear gear ratio as I wanted to increase the fuel mileage on this truck, and the M5OD transmission is more than capable. I got a good deal on the M5OD transmission, hydraulic clutch master with slave cylinder, driveshaft with slip yokes, clutch disk and pressure plate, transmission backing plate, (off of a 1989 Ford F150 5spd 2wd).
Yesterday I order the poly vinly carpet and new weather door strips.
I drove my 1978 F150 2wd with the new M50D tranmission to work (over 60 miles) and the tranmission runs great. The lower cab noise is great. I took the truck down the interstate going over 75 mph and the engine is reving much lower than before and the cab noise was greatly reduced with the M5OD transmission, my radio is not all cranked out to hear the radio now.
I planning a ZF tranmssion swap on my 1975 F250 highboy with a 400 c.i.d. blue printed engine.
