OEM Tranny Failures...POST EM UP

Trying to get a real sense of how many guys have had their trannys barf up a gear set or snap an input shaft. Seems the rule of thumb or guidance mods and others give is, stock clutch with stock tranny.

Just want to make sure this isnt another of those old rules from the pre-04 era that has stuck even with the upgraded components.

Thanks guys.

For what it's worth, I'm putting 334 ft lbs to the wheels on an 08 stock transmission. Clutch went out in ~10,000 miles (but saw about 12-14 visits to the drag strip). I replaced it with another OEM clutch + flywheel and it's been going well.

Stress and shock on the transmission is primarily through engagement, which is a sudden emission of power to the components. Once properly in gear, the factory gear sets have no problem in handling the strength.

I'm going to be tuning for some more power once I add my injectors, pump, equal length header, uppipe, and boost inlet hose... I'm afraid the oem clutch may begin slipping in higher gears, so I'm just a little nervous about stepping up to some kind of Stage 1 clutch.

I guess you're looking for a headcount for blown trannies? I destroyed mine 2 weeks after I got the car with one clutch drop. I knew nothing about subies then...

Thanks, youre just pointing out my exact reason for creating this post. I couldn't find posts about tranny failures from upgraded clutches.

tranny just went out (02 tranny blew. Believed aftermarket clutch)
Tranny go BOOM! (02 boom)
Flywheel/clutch problem (04 blew up)
tranny noise helppppp!! (03 boom)
I am now a member of Team Broken Tranny - Subaru WRX Forum: WRX Forums (lots of links to blown trannys here)
My car is dead..... (06 boom)

I only made 1 simple search and only looked at the first page of results. I know fastdak's BA (newer) tranny isn't on here and a bunch of other folks.

Guess i was looking for an 06 tranny broken from an aftermarket clutch.

Got any of those? I can find plenty of 02 "glass" tranny posts, not too many of what im lookin for.
