I was reading another post about the tendancy for the plugs on the top to shrink and leak. It said that by removing the carpet, i could access the tranny, and those plugs, and mentioned taking the plate off and dumping some ATF down there.
I would like to take a peak, one for my own experience and curiosity, and two to see if maybe i could actually locate the problem. I'll have to try and set aside some time for that before it starts gettin cold around here...

I've replaced the plugs. I also replaced the smaller boot seal to the tranny that was cracked and leaking. Did it through the cab of the truck. Peel carpet back, remove cover and access tranny. Not very hard, but you would want a shop to do it in.
My brother had a M5OD that started making funny noises. He was leaking fluid out through that little boot or the rubber plugs. By the time he figured that out it was getting pretty noisy. Then he traded it, so I don't know how much damage was done. He also had problems with his shift forks. Don't bump the shifter or rest your hand on it or anything as kotzy said. The shift forks are weak. Treat them right and they will last a long time, but bump them the wrong way and they will fail. Also, make sure it stays full if it is leaking or it is a quick death for these transmissions if they run low.
Good Luck!

My dad has always rode with his hand on the shifter in every vehicle he owns, and never had an issue, last FORD lasted 250,000 miles, traded to get one with a supercab since the family grew. I have always rode with my hand on the shifter, in a manual the ability to control what gear is your friend, you drive around town and somebody jumps in front of you, you can just break and hope it works, or you can shift, and go around or slow and then break, being able to control your engine backpressure and gear is the huge advantage to a stick, use it. If your hand is doing something else, changing the radio, holding a cup, holding a cell phone, ect. you are asking for trouble.

I always leave my hand on the shifter. My auto teacher in high school told me thats the way to wear down the synchros (which doesn't make sense to me... if the gear is engaged, wouldn't the synchro be "locked" anyway?) maybe he meant shift fork...
I cannot drive automatic vehicles. Its just weird. Even my F-700 cummins turbo diesel is a 5speed stick
Thanks for all the input men. I'd be pretty screwed without you all. (sorry i'm from north, yall just doesn't register
)

I had (and still have) these same noises in my 96 150, when the truck was still newish, about 35,000 I was able to convince my local dealership to rebuild tranny 
after rebuild it was ok for awhile, but the noise came back at about 55,000 and has been there ever since. It is a daily driven work truck that always has some kind of load on it, and I hope it lasts another few thousand before I need to replace it.

It might be but I would take a wild guess that if it was it would be the M5R1 version, not the M5R2 like is used in full size Ford pickups.
It's just made by Mazda, Ford owns a good chunk of Mazda.

Mine started making a quietish SSSHHH scraping type noise when engaging 1st from neutral and 3rd from 4th. It does this noise about 50% of the time
If anyone has a link to a exploded diagram for the M5OD on the net I would be grateful if you could post it

Well, i never thought ignoring the problem would help it, but it seems to have.
I think whatever was scraping must have scraped a little groove.
It doesn't make the noise anymore while the gear is engaged, but it does while shifting into gear.
This is all pretty funny to me. Next time my tire pops, i'm just gunna keep driving on it and see if it slowly inflates

Both the M5R1 and R2 are Mazda trannies. Ford owns mazda I think. I replaced the plugs on the back of my 89 m5r2 and put a little silicone on the plugs to be sure. Also replaced the 1-2 fork. It was grinding like crazy. Still gettin shavings in the fluid from that. Also the Shifter does have a plastic bushing on top and bottom of the "ball" along with some metal shims on the top. if the shifter has a lot of slop then I would bet the bushings are gone. Better replace them soon because the ball and shifter is steel and the housing is aluminum.
Good luck.

can the
can the output shaft bearing be changef without removing the transmission? is it in the tail shaft or the main case. I think i messed it up but jacking transmission up too high to get oil pan out. tranny works good just feel a clunking vibration that moves when vehicle is moving.
