P182E on Cadillac

Internal mode switch reports an invalid range in a GM automatic transmission

Severity not verified — if the car runs badly, have it inspected

Owners report limp mode and the transmission acting as if in neutral while driving with this code, but we found no source on how long it is safe to drive.

It gets more serious if:

  • Inspect soon: The transmission drops into neutral, goes into limp mode or the gear indicator disappears.
