So, full rebuild planned (new bearings, steel synchros, etc.), really considering the GT2RS gear change swap too for 1/2/3.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Howdy folks - sending my 2002 turbo 6 speed transmission into Bill Rayder here soon in Vegas for a rebuild. 50k miles on car. 3 and 4 synchros are buggers and it just developed a whine under power in 5th gear. So, full rebuild planned (new bearings, steel synchros, etc.), really considering the GT2RS gear change swap too for 1/2/3. Planning to keep car AWD, and power will be whatever a plenum, exhaust and tune get me. Weekend warrior, canyon carving and sport touring car that will see the track 1-2 times per year. When it�s driven, it�s very spirited, but not a dedicated track car. Still needs to be suitable for week long trips in Cali and Colorado and dinner dates. What can others say about the 1/2/3 GT2RS gear change out? The other big question is diffs - is it really recommended for Wavetrack TBD or a Guard LSD for my intended use? OE diff is working fine, but these TBD and LSD are definitely just a "While you're in there consideration" that wasn't in my plans for the car (or at least I haven't driven it hard enough to develop a need for an alternative diff yet!). This transmission service wasn�t really in the plans, but the whine in 5th gear made it mandatory while engine out here soon. ~6500 for full rebuild and GR2RS gears, another 3k for wavetrack, and 4K for guard. Thoughts on the diff??

POST 2Original post

Sound way over priced. I had mine rebuilt a couple of years ago by Gbox, it was $3,750 plus about $300 for shipping. They have a great reputation and I think they can offer most of the options you are talking about. http://www.gboxweb.com/index.html

POST 3Original post

I should say that mine is a 996 C4 not a Turbo.I am sure they do Turbos too.

POST 4 / ORIGINAL POSTEROriginal post

Yeah the basic rebuild is right around 3500 as well, so sounds similar. Swapping out the 1/2/3 gears for GT2RS gears ups it to the 6500 mark. Then there’s the diff consideration on top of that, which is what I’m sourcing assistance considering. TBD or LSD for 996tt with less than 550 Hp required or beneficial with AWD for spirited street use?

POST 5Original post

LSD on the 996 isn�t as important as an LSD on some other cars. I doubt you�d notice it except under heavy braking on the track.

Agree, I never really missed it on my 996 C2. However that was with medium track duty, maybe a more extreme setup would require it.

This is a source reference. Confirm exact model applicability in the original material.
