Transmission Generic OBD-II Low

What it means

P0955 means the transmission control module sees a fault in the circuit for the manual (tiptronic/sport) shift mode — the feature that lets you select gears yourself. The automatic transmission still works normally; you simply lose manual gear selection until the switch or its wiring is repaired.

Low

Can I keep driving? Yes — the transmission still shifts automatically; you just lose manual/tiptronic gear selection until it's fixed.

How to diagnose & fix

Work through it in order

Read freeze-frame data and confirm the fault is in the manual-mode circuit, not a broader transmission code.
Inspect the manual-mode selector switch and its connector for damage, wear, or corrosion.
Check the wiring between the switch and the TCM for opens, shorts, or chafing; repair as needed.
If wiring and switch test good, have the TCM diagnosed and reprogrammed or replaced.
