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

Has anyone installed 02 or later 996 Gearbox in earlier 996?

POST 3 / ORIGINAL POSTEROriginal post

I do understand that the exterior dimensions are slightly different. I have been told that "it isn't possible". I have an opportunity to get a later box that is in excellent condition. It would be very much appreciated to find out how this swap was done, especially the "problems" you encountered. thanks for responding, that itself was a treat-Mark

POST 4Original post

Mark, Can't comment on your source of info. Just that I have actually done this on my car. I am not sure what the differences were if any but it didn't require different parts or slow anything down. Like I stated... 1999 C2 chassis with a 2003 3.6 engine hooked up the original1999 gearbox and then later swapped for a 2003 gearbox. Existing lightweight flywheel and clutch were transferred over for new gearbox.

POST 5 / ORIGINAL POSTEROriginal post

we do these cars everday........i've been used to being the "testdummy" on mods in the past and am glad to see that you've beatn't me to the punch. have a great deal on brand new gearbox and will go ahead and "fit" it in 00 car.....thanks-Mark

POST 6Original post

The only real differences are the gear ratios as these were made for the higher torque/HP 3.6 motors. The difference is fairly minor, however.

POST 7Original post

The difference in gear ratios is so minor that it is non-existent. There are absolutely no differences in gear ratios. G96/00 and G96/01 1st gear: 3.82:1 2nd gear: 2:20:1 3rd gear: 1.52:1 4th gear: 1.22:1 5th gear: 1.02:1 6th gear: .84:1 Final: 3.44:1

POST 8Original post

Doh!! You're absolutely correct. I grabbed the wrong gear chart. In fact, all early 6 speeds including Box S have the same ratios!

POST 9 / ORIGINAL POSTEROriginal post

some have said in their rejection opinion that the physical differences at the nose of the 02 and later cause fitment problems that cannot allow u to get around? I've seen both and cannot see such issues. basically, shouldn't it "bolt up" in a 00?

POST 10Original post
