M5OD rebuild thread!
So I'm driving to work yesterday on the highway with it in 5th and then all of a sudden I hear this crunch and metal on metal grinding noise. Then the engine started revving (cruise control), 5th gear had turned into neutral. I pulled over right away and luckily the other gears all still worked so I could limp home. I guess 50K miles on 32 inch tires without regearing the stock 3.73 gears must have put some extra stress on the trans. Not to mention most of those miles were on the highway in 5th Gear.
I think I am going to rebuild this trans, seeing as I can get away with driving my mustang for another month or so hopefully but another option I was thinking was to perhaps install a M5R1-HD which I thought was heavier duty? Does anybody know if this would work? Is the bellhousing the same?
Suprisingly, I didn't find all that much info on here as far as rebuilding it... Spdrcer34's thread had potential but he never finished it. And figures therangerstation.com, which has a pretty good tech library, just recently got hacked and its not up right now.
It has 120K on it, so what would you guys think the condition of the synchros would be? definitely replace/possibly/or could they be fine? With 120K on it and the fact that I have it all apart to fix fifth gear I figured I should probably go through the trouble of rebuilding it all, but then again I don't know. Is that even a lot of miles for a tranny or do they typically only need a rebuild after like 250K?
If I went the rebuild route would this kit contain everything I need (aside from whatever is broken)?

Can anybody recommend a good cheap place to get a rebuild kit? How about were to buy the replacement parts I'm going to need?
Any one know if this trans changed after 97? Some sites like this state that their rebuild kits are only good for 91-97 explorers: http://www.drivetrain.com/mazdaM5R1.html
As I go through the tear down and assembly of this I'll be sure to take and post lots of pictures on here. I'll post any thing thats specifically useful off the ford cd I have as well. Now I'm off to construct a gear puller....
