This is not a probability of success.

I have just aquired a 2nd gen C2 Tip S and took it on its first long run today, I have noticed that when the box downshifts from 3rd to 2nd it sometimes does so with a very noticeable clunk, other times the downshift is seamless.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

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.

2 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

I have just aquired a 2nd gen C2 Tip S and took it on its first long run today, I have noticed that when the box downshifts from 3rd to 2nd it sometimes does so with a very noticeable clunk, other times the downshift is seamless. Can anyone tell me if this is normal or indicative of a problem ? It only happens when the box is downshifting from 3rd to 2nd and not all of the time sometimes the downshift is as seamless as all of the other gear changes. Any advice/ideas would be welcome. The car is a 2003 with only 35K miles on it.

POST 2Original post

Occasionally I experience something similar, e.g. when decreasing the speed a bit "sharply" (say a stop-light surprises you on a 50 mph road, or similar) and it has to go down in gears quite quickly, but it is quite rare. Someone suggested "90% of Tiptronic issues goes away if you change the gearbox oil...", which I haven't tried yet (3.6, 2002, 78K miles). Would be interesting to hear other's experiences.
