I wanna put a m5od in place of my dead c6 in my 80 302 4x4 I have a 92 doner truck what all swaps over? Will pedels fit?

 

The pedals will not fit, they are different on the 87-up trucks. I believe some people with fabbing skills have made them fit, but I don't know what exactly was involved.

Get your donor, and then go to the junkyard and get some pedals out of a 86-down truck with the hydraulic clutch. 80-thru around 82 had a linkage clutch and that won't work for you.

You will have to cut the hole for the clutch master cylinder mount in the firewall, but other than that it should be a bolt in. Make sure you take the two red/blue wires that go to the side of the c6 tranny and twist them together, or after the swap it won't start. Those are the neutral safety switch wires.

This swap should be worth it in gas savings you will get.

 

I always heard that the Mazda transmission was the weaker of the transmissions used in Ford trucks. What's your motive beside the extra gear, if you don't mind me asking?

 

I have the donor truck with brand new clutch and flywheel but the motor is done and im board lol

 

i think you will need a diffrent flywheel. it will bolt on but if i am not mistaken the weights are diffrent i think it changed mid 81.

 

That's true, I am glad you brought that up. You will need to buy a flywheel for your 80 302. It will be a 28oz inbalance. The later one is a 50oz.

 

If you do get the M5OD, before installing it into your truck, replace the 3 rubber bushings on the shift tower. They are accessible by removing the tranny hump inside the truck, but much easier doing it when the tranny is in your hands.


Ford sells an update kit for this, replacing the rubber plugs with copper ones, that don't fail.


The number 1 cause of failure of these transmission is those rubber plugs leaking, and they only leak as you drive, and you end up running the tranny dry, witch burns it up.


Otherwise, they're good "daily driver" trannys. Don't abuse it to much, and don't tow to heavy with, and you'll be fine. They do have a really tall Reverse gear, be aware of that.



And since your truck is 4x4, you will need a 4x4 tranny.



Heres the plugs i'm talking about. The 3 bumps facing the rear.

 

It down look like I have room for the slave master cyl threw the brake booster?

 

Use the donor truck location as a pattern. They were all in the same location, but your firewall is not pre-punched for it like the later models are. There is room for it.

 

Yep u guys are right there is room on the fire wall now will my factory tcase bolt to the m5od its a bw1345 I think?

 

I have a 84 F 150 with less than 100,000 miles on it. Other than some slight rust at the bottom of the area behind the seat, it's in great shape. It has a 4.9L/ 300 straight six engine. It gets lousy gas mileage. I also have a Ford Probe that will soon go to the crusher. It has the top load 5 speed transmission. I was wondering if I could swap the Probe 5 speed into the truck to get acceptable mileage.

Can anyone help me with this decision? Today is the first day that I have considered this, so it is early in my research.

 

The bell housing bolt pattern won't be the same, so it won't work.

 

I have an '89 F250 with 302/M5OD and it is hooked up to a 1345 transfer case from the factory, so yes it will hook up.

 

Thank you because its was hooked to 1356 is the adapter plate the same?
