Hardened Tranny Gears?

Its just a specfic heat treat process, different heat and cooling patterns leave different effects on various metals. I used to work in a metal forming shop. A place of such, could probably put these OEM gears through one of those specific heat cycles and have these tempered for you.

doesn't that make them more brittle? or do they have methods of preventing that?

heating then quickly cooling makes them hard but brittle then you heat it up and cool it slowly to take out the brittle but keep the hard. Depending on what qualities you want the metal to have dictates how many times and at what temps you do this.

it would probably be possible to get them nitrided as well this is what they do to cranks to make them as hard as forged

also, look up micro blue. alot of F1 teams use it. you can even do rods and so on also. a local got tired of bowing his KL trannies left and right, and ended up having a trans fully done up using it. hasnt blown another trans since, and that was like 4-5 years ago.

ok, so am I missing the point here? it's not actually the gear that goes out, but a bearing? cause I looked up the micro blue website and all I could find was chains and bearings.

the gears themselves go, the teeth get sheared if i'm not mistaken

ok, that's what I thought

micro blu is a process. you can do it to anything you want. rods, gears, cams, anything.

Like I say, there are many, many methods. yes some do temper them, which makes them just crack, rather then bend.

Lots of different heating, cooling (heat cycle) methods do lots of different things. I dont know them all, I was just stating that it would be very wise to check into them.

so then where does one purchase oem transmission gears?

Don't you already own 5 gears right in your tranny? Rip it up and take the lovely car off the road for a few weeks.

ok i found a thread to ask this.
what does cryo treated, do for the gears?
the same as heated...?

only one resource out of hundreds...
