Getrag go boom
 

Hard shift to 2nd with a 949 twin disc. 6spd is fine. Getrag go boom. :mad:

Used or new?

Well on the positive side of things, the Getrag is ~1/4 to 1/3 the cost of a 6 speed... unless it was a new one.

Used. Supposedly from a 40k mile car.

~250 twerks right? Thats a lot less than those are supposed to be able to handle...

Miata : v8 shattering torque :D

Old crack in a tooth that shattered or a pinion deformed like a corkscrew and stripped all gears?
I.e. too much power/grip or just a flawed unit?

And in cars that weigh twice as much

A lot of grip - 12" road race slicks. A lot of power - more than 250ft/lbs. An on/off clutch. But yeah, a lot less weight. Not sure what failed. Not gonna take it apart until I see if I can get the yard to warranty it. Sure, another one is cheaper (or free under warranty) than a tranny but if it won't hold up the price doesn't matter.

<p>Wheel hop? &nbsp;I'm guessing not as you would have mentioned it.</p>

Well.....that whole assumption thing. Wasn't the diff after all. Somehow something moved permanently on that 1/2 shift and the driveshaft flange was grinding on the ppf.

Did you take any pics of your finished install?

Well that's interesting. Wonder which mount was the culprit.

My bet: PPF. That thing is flexy.

-Ryan

Haven't quite figured that out yet. I would think ppf also, but I don't understand how it would have stayed over too far. Should have just moved back. I'll look at it closer tomorrow.

Carnage pics?

^ Read post #1, skipped the rest.

sure

Which model Getrag was this?

The Getrag did NOT fail.

Do you have picture proof of that? :D
