"Our complete transmission rebuilds include, but are not limited to, the following parts: 5 OEM Synchro Rings 4 OEM Dogteeth (Engagement Gear) 3 OEM Operating Sleeves (Sliders) 1 OEM Gasket & "O" Ring Set OEM Energizing Rings OEM Brake Bands OEM Anchor Blocks"

From my research on this board this isnt a "rebuild" but a refresh or refurb. Is this worth it and visable for a 915? Just need them to flip the R&P and $1900 wevo kit to run behind a 3.2 or 3.6. Opinions welcome....

Anybody have any experience with Vertex? http://www.vertexauto.com/index.php?pg=pro...ail&sk=4269

Just finished assembly on a 915 wevo trans. My porsche mechanic told me it takes 8 hrs plus parts for a rebuild (approx). I will say that the costs add up depending on how used your trans is. I found an '80 915 that had only 30,000 mi on it and so it needed no new parts. But....wevo(1990), GT LSD(1900), flipped R&P(4hrs), new wevo side cover(325), wevo linkage kit (595), and installation(~600)....it adds up. See pic's...Good Luck!

Wicked cool! How do you shift it?

tranny porn.

Thanks for the info.. is that plumbing for a trans cooler I see?

Thanks for the pics. Nice looking box ya got there.

I have to warn all the people who are looking into the 915's.

PLEASE check the pinion bearing race. 90% of them are loose in the trans. This means you will have big headaches later on if you dont fix it NOW while the tranny is apart.

I'm running across "tranny builders" that dont even check for this. They check the actual bearing and pay NO attention to the race in the case. ASK questions. DO NOT let them "spike" it in place. It doesnt work. It will last for a couple thousand miles and come loose again.

Please be smart when choosing a box. Dont pay good money for a used box with a pinion bearing issue. Fixing it properly is NOT cheap.

Hey B, why is that a problem in the 915 boxes? I have not yet found a loose one in a 901 (not that they don't exist, I just havent seen one). Is this a design flaw, nomal wear, etc?

The aluminum is wearing out. The mag cases dont seem to have the issue as often as we are seeing it in the alum.

Also: in 78 the 3.0 engine came out along with the alum 915. These cars (I feel) were the first reliable 911's to actually hit the market. So.. they where driven and driven and driven. Bottom line: most of the 915's have high mileage on them because people drove the cars more often. I have seen 3 loose bearing races in the 901/914 boxes out of hundreds I have pulled apart/built. No fix for the 901/914 box. At least we have a fix for the 915. I have only pulled apart 1 915 that didnt need the fix for the race. I'm only up to 40 or so of the 915's however.

Good info hrmmm

Is there no escaping the $5000 tranny rebuild? The more I look at it.... keeping my 901 and using a smaller displacement less torque six say 3.0 instead of 3.6 is looking like reality.

Ya, but you can always upgrade later

Escaping.. not really.

We spend 10-12k rebuilding a 6cyl engine. You will find people spending 3-5k on 901/914's soon as they begin to wear out completely.

I built 3 901/914 trannys on NEW Porsche cases back in 04. I think Porsche is now out of the 901/914 tranny case.

Do you know which mag case is cool and has a better track record? 915/xx ?

I do not, but I know who does!

I really dont want to do this, but I suggest calling Hayden at WEVO and asking him which MAG case to look for.

PLEASE PLEASE do not bullshit the guy or take up a ton of his time. He is one of the few vendors I deal with that I semi protect from tire kickers. Please respect that.

That being said:

650-595-5772

I'm betting Tracey can answer the question or (ask Hayden for you while you are on hold)

I dont want to sound like a dick.. I just protect my vendors/friends the best I can. I hope you understand.


B

Thanks...

Tirekicker? Hrmm Im just looking for a reliable solution. Furthermore, I think you know what your talking about from searching this board so... Wevo sideshift seems to be the "best" solution... so they would be getting business from me buying that kit no. Maybe not direct from them but from one of their vendors.. Well if I can find a good used mag 915.

BTW what happen to the club store? Click on it and it brings me back to the forum?

Is this the fix your talking about? Makes sense now...

For you guys that know way more then me...Well that's pretty much everyone on the board.

It seems that my tranny is a 916. Someone posted pictures on another thread I made and it seems to be the same numbers. That one was a 916 tranny also.

Well OK I called Wevo to see about getting there gate shift kit. They said it wouldn't work.

Now I can't say I am completely happy with the way the tranny works. I did get wevo tranny mounts and ordered the reverse lockout because I dropped the other one HAHA

So I guess what I am wondering is what my options are for improving this trannsmission???

You can buy direct from WEVO.

The ecomm broke when we upgraded the site code back a few months ago.

Tell Tracey/Hayden we sent you (club/Me) I know them well.

Yes. That is the fix.

The mag cases have a iron insert for the bearings whereas the aluminum cases do not.
