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.

Have a 2003 C2 Cab with Tiptronic. It's been sitting a lot due to work circumstances. Today I took it out, after warming it up properly of course, and was accelerating into highway traffic from an on-ramp. Under acceleration, I shifted from "D" to "M" and downshifted to try to gain more positive acceleration (maybe I downshifted one too many times but rpms still well below redline - maybe 4500) and the Tip disengaged: transmission was effectively in neutral without the gear shift being in "N." I just coasted to the shoulder and thought the tranny was toast. In the process I switched back to "D" (automatic mode). Still nothing. No gear selector light on - which was accurate since the car was not in gear though the gearshift was in "D" (but also I didn't see the dreaded "4th Gear" transmission fault light blinking either). When the car slowed down (though not stopped yet) it slipped back into gear (once again, it was in "D" now - auto mode) and then it operated normally the rest of the drive. Anyone else had this or know of a similar occurrence/what might have caused the Tip to step out of gear? I'd like to believe Porsche built in a protective disengagement action in its transmission algorithm to protect the auto gearbox from undue stress, but I know that scenario isn't realistic.
Internal clutch or torque converter? seemed to slip out of joint, then appeared to slip back...if that's possible. But not a transmission guy so just guessing....
Thanks for any ideas that would explain this first ever occurrence of my Tip flaking out.

use the switches to down shift................... why go out of your way to beat on it?
maybe you found a rare use case outside of the shift map............
A few things come to mind here.
1. Moving from D to M and vice versa should never cause a problem.
2. You don't need to switch to M in order shift via the buttons.
3. If you stomp on the gas while in D, the transmission will automatically drop to the lowest safe gear.
I've had my Tiptronic C2 for 7 years and never experienced what you described.
