Will 997 c2 transmission fit 996 c2?

[996]

My transmission on my manual 99 c2 3.4 needs rebuilding but i have been offered a 2004 997 c2s manual transmission......will it fit? Will anything else need to be changed e.g mounts/shafts?

Maybe it's just a typo but there is no such thing as a 2004 997 "anything". 997 started in 2005. I'm sure you could just ask a tech at a dealer or an indie and they would be able to tell you if it would fit... It should fit.....

I believe in the UK cars are "registered" based on the year they made rather than model year or when they were first purchased.

Hi its a 997 the very first ones not a 996, for arguments sake its early 2005 registered.

Does anyone here know if it is compatible?

I get whine at speeds above 30mph in 3rd,4th, 5th and 6th when on the gas, when i come off it disappears, from what i have read its likely to be the pinion bearing and/or main shaft bearing. It doesnt pop out of gear and engages all gears smoothly.

Only used to happen in 6th but has got worse over the last 6 months even though its more of a garage queen.

Mileage is 51,000 miles. I did change the gear oil on the last clutch change which was about 3yrs ago (5k miles), i checked it on my ramp and the fluid level is correct however its not light golden colour anymore, its gone darker.

Hi loren yes your right over here in the uk cars are registered according to their build date not registration date.

Why not get a new bearing fitted? Have a word with Mike at Sports & Classic in Knutsford, as he does quite a lot of rebuilds on these boxes.
