WTB BROKEN 997TT or gt3 6spd
 

Well I bought a "COMPLETE" disassembled 997TT transmission on here a while back. Well guess what, it wasn't complete. I"m trying to assemble part #s, but what might be easiest and possibly lower price point is to buy a broken complete transmission. One from a wreck or such. My case and gears look wonderful, but there is multiple shifting parts missing.

If you have something, let me know. I haven't had the chance to cross reference the 6/7 transmissions to see what all is actually interchangeable as I'm just aware of the improvements Porsche made with gear strength.

I know this is a stretch on PP, but I've posted on h20 pumper heavy sites too :D

But I know those like M Monson visit here and may have such laying around collecting dust.

Cheers

There's nothing cross compatible between a 997TT and a GT3 gearbox other than the LSD. The 997TT uses triple ring synchros on all gears, and is about 30mm longer over all as a result. If you are going to assemble that case, you must get only 997TT parts.

Unfortunately I've got nothing. I stopped doing any kind of service work on the boxes before that one came out. Bill Rader and CMS do most of the high power high performance work on them.

Bill Rader in Las Vegas might be able to help.

I dropped of my 915 trans to him for a rebuild and toured his shop. He had many Porsche trans, from 915 to the latest/greatest water cooled GT3 trans it seemed... also works on Audi and Lamborgini boxes for various race teams.

Thanks for the thoughts and responses. Appreciate the insight on TT/gt3 box differences. I am obviously not turning the wrenches on the box. I actually thought the boxes were similar with just completely different gear stacks and mainshafts. Its at a local Porsche shop but I am simply trying to run down some parts to attempt to keep this within a relative budget for a back up transaxle.

One more question Matt, if I still have your attention. MY 6GT2? is it more gt3 or 6tt inside the trans?

Yes. :D

It's a GT3 gearbox (with pump and cooler) but with 996TT gear ratios inside. Will also have steel synchros in 3-6 like a GT3. And of course an LSD, which the 996TT usually doesn't have.
