Transmission replacement compatibility???

I think the truck meant transmission.......


I snapped the main shaft from the tranny to the transfer case last week...oops. I have an 03 manual tranny. Can anyone tell me what years would be compatible?

There's a couple 04-06's with less than 20k miles on them at a local scrap yard for killer prices. I'm not even looking into rebuilding this tranny. It's time the tranny was laid to rest, lord knows all the abuse it's already taken


On a lighter note, all that's left to replace is the frame, transfer case, driveshafts, and body.....then I'll have rebuilt the entire truck. lol

Any 01+ manual trans from a 4.0L SOHC truck will work. I found that my new 06 tranny w/ 10k on the clock, has different gear ratios in the trans than my old, stock 01. I hate it.

I don't remember the specific trans name, m5rodHD....something like that. HDs on behind the 4.0L SOHC....but you can use any one of the m5rod's.

I pulled out from a stop sign and turn right....got on it a little harder than I should have(not even close to the worst launch I've done in the truck)and all of a sudden it felt like the truck was in neutral. I messed with the transfer case making sure that it wasn't in neutral then came to the realization that my truck was dead right in the lane of traffic. haha
Yeah, I'm still alive. I've just been hella busy with work and working on my house.





So.......HD or not? What's the difference, I didn't completely understand that post.

Anyone know about the difference in gearing with the years?

are you sure the "chain" in the transfer case didn't break?

The rear wheels were locked up completely. I had to, literally, drag it a mile down the road to my dad's house. I had my friend pick it up on a roll back and he's the one that told me the main shaft from the tranny to the transfer case snapped. I'm just going by what he said. I'm gonna go over to his shop this weekend and see for myself.

  • Throughout the 90's and up through 2000, all Ranger manuals were M5OD-R1 made by Mazda, regardless of engine displacement. Besides internal ratios, the only other difference was in the outer cases which were different to match the individual engine bolt patterns (these transmissions have a bell housing that is integral to the transmission case casting).

  • In 2001, an upgraded Mazda trans called the M5OD-R1HD was introduced for use only with the 4.0L SOHC. The shop manual shows that the synchronizer blocking rings for first and second are different. The first gear ring is larger in OD and ID and the second gear ring is of a different construction. It stands to reason that the shift fork, synchronizer sleeves and the cones on the matching gears would be different to match the uprated rings.

    Going only by the shop manual, it appears that the rest of the M5OD-R1HD transmission uses the same construction as the M5OD-R1. It would take a trip to a dealer parts counter to verify that all other internal part numbers are actually the same.

  • 2001+ 2.3/2.5/3.0 continue to use the original style M5OD-R1 as in earlier years.

  • All 4.0L use a closer ratio gearset as compared to the 2.3/2.5/3.0 engines. It doesn't matter whether you're talking about 4.0L OHV or 4.0L SOHC, R1 or R1HD.

    3.40 / 2.05 / 1.31 / 1.00 / 0.79 (4.0L Engines)
    3.72 / 2.20 / 1.50 / 1.00 / 0.79 (All Other Engines)

If its from an 01-current 4.0 SOHC it will be the HD version and be a direct bolt in. You will have to swap the extension housing from your current tranny to the new one though.

Any 4.0 transmission will work.....the transmission you and all '01+ Rangers have the M50D-R1HD.....

I agree with above, you need to pull the transfer case apart and make sure it wasn't the chain inside it didnt break and lodge up inside causing the main shaft to bind.....

Awesome thanks guys.

I'm on my way out the door to grind some gears but when I come back friday evening I'm gonna stop up at my friends shop. I'll get to the bottom of it. He's an honest dude that runs an honest business and has a race team on the side so I trust him fully. I wanna see the carnage as well

We'll get her figured out soon enough.....Now I just gotta order new rear shocks(both blown/leaking oil), new coilovers(one side coil is almost completely bottomed out), and she'll be good as new.....til next time I drive it

i meant by jacking the front end up, and then spinning the driveshaft, if it turns then you know you won't have to pop the t-case open

wow, i gotta bring my camera to the shop next time.

I seen the output shaft and it's completed twisted/snapped in half!! ROFL!!!


The mechanic asked me "What were you doing in this thing??!! Wholeshots?!? I've been working on cars for 23 years and have NEVER seen anything like this!"

I almost fell on the floor laughing when he said that and seeing that shaft in two on his bench.


Anywho.........it's definitely the transmission =]
