Mazda M5OD Transmission

Post #1 by fordman41291 » Fri Jul 09, 2010 12:20 am

is the Mazda M5OD tranny any good or is it junk?? people are calling them Mazdog's is that just a name for it or does it mean that the transmissions are garbage?? this is the 2nd Mazda M5OD tranny ive had. i had a M5OD M1 in my Exploder and an M2 in my current 94 F150. I havent had to replace a clutch yet but i can tell i might be gettn close its hard to put in first and reverse sometimes. should I put a new clutch in or just junk the entire tranny and put in a ZF?

the M5OD is fine for light-duty use, but not for heavy use. in general, it is a light-duty gearbox, and as a result is more prone to various failures when subjected to heavy use such as towing, overloading, or abusive driving.
the other major annoyance of the mazdog is the excessively high gear ratio on reverse.
for a gently used highway vehicle, its a good unit and will last a long time, but its not suited for heavy use.

I towed with it just once and it did ok, i mean it wasnt struggeling or anything but i think i may have pulled like 500 lbs. 400 lbs. just the trailer. the extra hundred for the cargo (scrap metal) so i take it this bastard transmission wont be good for hauling a 2 horse, horse trailer than will it?

topic of the day mazbog transmission found in mazda and ford rangers otherwise known as the 5 speed syncromesh trans. it is good as a stock 4 cyl truck trans and i am speaking from experience owning two mazdas a 2300 and a 3000, 2300 is a work truck has seen many many payloads of over 2000 lbs uphill driving and such its a decent trans just dont expect any kind of performance out of them, i have rebuilt it two times in the past 3 yrs. i am dying to find a tremek.

I would use it. Anyone who cares about his horses will drive fairly gently and the Mazdog will tolerate that just fine so long as you never pull it hard in fifth gear (OD). You will really hate that tall reverse gear if you have to back a loaded horse trailer up much of an adverse slope though.

A ZF trans would fill the bill far better.

Kinda late to the party on this post but I'll chime in on it also. The M5 that's in your Full Size truck is slightly different than the ones in the Rangers. They're not the best in the world but for general day to day use and occasional towing they are fine. I have the M5OD in my 92 Bronco behind a EFI 300. It goes where I want, when I want. If you were going to be using it for heavy duty towing all the time, I'd recommend looking for the ZF5 to replace it with for when/if the M5 gives up on you. Take care of your drivetrain and it will take care of you. Like was said in the previous post, if you're pulling your horse trailer, you're not going to be over driving it.
