We all know that the transmission becomes a weak point on s2000s once you start putting down roughly 500-600whp. But it seems like it may be inconsistent problems and some people are putting down huge power w the stock trans and not having a problem even after many many passes at the Drag Strip. Hell some people have stripped 2nd gear just rolling into the throttle in 2nd w 500whp+.

I understand driving style may be a contributing factor. however the point of this poll to possibly see a correlation between years and which year transmissions show the highest failure rates. For this reason, if you blew up your trans and swapped to a different year and are now running strong no problem. The please vote twice. (example. AP1 guy swapping to an AP2 trans)

There is a difference between 04/05 trans and 06+ transmissions. (Honda has a TSB of improper clearances for some 04/05 transmissions. so I
am curious if we'll see higher failure rates w the 04/05 AP2 trans vs the 06+)

I do not know if Honda changed anything for the AP1 transmissions. if they did I will add the year split to the poll option.


*to be clear. This poll is for damage to the trans because of high whp/tq. Do not include clutch failure or synchro failure due to driver error.

please post the following for reference

Blew second gear during a race, girly 542whp. Held up fine for highway but not for MT´s and weekend fun. Low miles on car and tranny.

 

-Power level (whp/wtq). 700whp 500tq
-rear diff (OEM) upgraded mount stiffeners
-miles boosted ~3500
-your s2000 year. 2005

Tranny seems to be extra notchy in second, we will see.

I think clutch type, tires and tranny fluid are also super important.

GM synchromesh fluid.

I have to clarify something about my trans failure, it wasnt the case that split, but the section behind that, split it almost completely in half on a 4th gear highway pull, stock trans held for about 700 miles at that power level

FWIW. When I put the PPG gears in, I will take very detailed pics of my OEM gears/Synchros etc and add them here

 

Joeyballs, That would be cool to see your internals after all the beating you've given it. Refresh my memory. Did you have a trans failure or just uprgading Just Cause?
