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.

POST 1 / ORIGINAL POSTEROriginal post

My 99 C2 tip isnt regularly shifting from 4th to 5th gear in automatic mode. When I switch to manual, it shifts perfectly and then I can switch back to automatic in 5th gear and it stays there without a problem. This trouble is new to my car, has anyone had a similar experience? What is the likely problem?

POST 2Original post

HAVE YOU CHECKED THE AIR PRESSURES LATELY?OR HAVE YOU REPLACED ONE OF THE FRONT TIRES?I HOPE THIS HELPS.

POST 3 / ORIGINAL POSTEROriginal post

No, please explain what the tire pressures have to do with the shifting.

POST 4Original post

Did you change the ATF lately? What mileage is your 996? High mileage automatic often fail when ATF is changed due to change in viscosity. This can be remedied by putting in some CD-2 ATF conditioner that will help seals to expand and thus upshift as normal. You may want to try this even if the ATF wasn't changed. You may also have something stuck in the slushbox so changing ATF and filter (if not done already), may help. If all else fails, take it to a Porsche specialist for diagnosis.
