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

Hi, I have some noises from my gearbox, I suspect it's the common pinion bearing issue. (See this thread for details, https://rennlist.com/forums/996-foru...d-in-gear.html ) What would you do: 1. Send it for rebuild to GBOX. Cost will be $2500-$4000 depending on what's broken. It's a minimal of $1200 labour, the bearing it self is $500 and then some other stuff. There is no 2nd gear pop out. 2. Drive until explodes and get a used ebay transmission. These can be found starting at $1500 I don't mind DIY and have no problem replacing transmissions. Fixing the pinion bearing is a little over my head and I will not attempt that as my first transmission project. Car is 1999 3.4 C2

POST 2Original post

I had the same issue and my Indy ordered a rebuilt one from GBOX and had it in 5 days. Comes with the second gear fix built in. $4200 delivered to Grand Rapids, MI. Also included return charges for core.

POST 3Original post

My 996 had a tranny built by GBOX and functioned great, however, when I put a 997 engine in my car I got a 997S tranny as well for NORSPEC Dismantling. I sold my GBOX transmission and haven't looked back....The transmission is so much better then what was in the 996. So may be that is an option....Going to their EBAY store you can find a bunch of 997 trannys https://norspecdismantling.com/ if it is something you want.

POST 5Original post

Had mine rebuilt by Gbox included the pinion bearing about 50k ago and that meant shipping from Canada to their location and back. They were quick and I was very satisfied. If ever needed again I would use their services. Buying something like that on Ebay is a roll of the dice and it could be great or also needing a rebuild after you've installed it and taken a road test with it.

I believe so since my 997 3.8 was mated with my 996.1 transmission for some time so imagine the reverse is true. Dundon motorsports can tell you for sure.

POST 7 / ORIGINAL POSTEROriginal post

Quotes source post: 15712586

do you remeber how much you paid? Seems like internal parts is pretty pricey, gears are several hundred dollars.

POST 8Original post

This was about 6 years ago and the price for a synchro refresh and the pinion gear replacement was $2800.00. Pete

POST 9 / ORIGINAL POSTEROriginal post

Thanks! Sounds reasonable for a minimum job. The fixed price for labour seems to be $1300. But parts are very pricey, if gears are damaged it quickly adds up!
