Time to crack open our Porsche Cayman's broken transmission

In reply to Keith Tanner :

I hear they were dogs off boost. The 5 speed helped. "Enough" seems relative haha

It's happening!!

Ok, this thread delivers

So I was going to post nothing until the next update is ready (gotta keep those traffic numbers up), but it felt wrong to leave you guys hanging so I'll post this before I go to bed:

I found the problem, and I should be able to fix this transmission.

The details and photos will turn into the next project update...stay tuned!

Just knowing that is making me want to find a broken one for cheap...

I've driven two but only on track. Not sure it's so much beings dogs off boast but more of classic 70s turbo lag.

In reply to Tom Suddard :

What are your "while we are in here" plans in regards to the clutch, throwout bearing, dual mass flywheel, etc? 

I'll change the clutch and throw out bearing, but will likely keep the dual-mass flywheel. This will be a street car, and I'm on a budget. We swapped to a lighter aftermarket clutch and single-mass flywheel on the Boxster project, and it was noisy and hurt driveability on the street.

Depending on the life it's lived, it might be time for a new flywheel too. Definitely keep the dual mass on anything but a dedicated track car.

Sounds like it was an obvious, and hopefully fairly simple, fix. Fingers crossed for you! 

I well recall being the only guy in the Acura store that would (or could) do trans work, having a dedicated bench and a nice selection of select-fit shims and such right there. I was sorely bummed when Acura decided to centralize repairs and supply only units at the dealer level.

This should be fun, watching you guys dive down the hole.

Hey! I just overhauled a '92 NSX transaxle and am envious of the dealer guys who had all the right tools back in the day. The factory service manual was pretty good though.

EDIT: Hopefully this won't derail the thread, but what was it like working on these units back then?

And now, the conclusion to this week's Porsche Cayman cliffhanger:

[Can we fix our Cayman's transmission? Or is it a $15K dealer repair?]
