Stuck in Gear 8
High severity
What it means
The transmission has entered 8th gear but cannot leave it on command — typically a stuck shift solenoid or a stuck-on friction element holding the 8th-gear pattern locked. The TCM forces limp-home mode if upshift/downshift attempts fail repeatedly.
Is it safe to drive?
No — stop driving
