I just checked the fluid level , after operating temp very small amount of fluid started dripping from the filler plug.

I did change the transmission fluid about a year ago and filled it at the correct operating temperature, but I’m going to recheck the fluid level to make sure it isn’t low.

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 1999 Tiptronic Porsche Boxster feels like it is slipping, accompanied by a loud/hard noise when accelerating quickly. However, it drives normally if I maintain a steady speed. I ran a Durametric scan and got the following fault code: Tiptronic Transmission G40: P0732 – Gear Selection Monitor, 2nd Gear Based on my research, it appears that the Transmission Control Module (TCM) has detected a mismatch between the engine/input speed and output speed while the transmission is attempting to engage or operate in 2nd gear. I’m planning to go through the checklist below and hopefully avoid having to replace or rebuild the transmission. In the meantime, I’d really appreciate hearing from anyone who has experienced a similar issue with a 986 Boxster Tiptronic. If so, what was the root cause, and what was the eventual solution? I did change the transmission fluid about a year ago and filled it at the correct operating temperature, but I’m going to recheck the fluid level to make sure it isn’t low. Durametric does not have real time solenoid Actuations option for the transmissions like the engine module. Any advice or experiences would be greatly appreciated!

Low fluid level is the most common cause of P0732.

I just checked the fluid level , after operating temp very small amount of fluid started dripping from the filler plug. the AF service had been done about an year ago.
