P2701 Transmission Friction Element B Apply Time Range/Performance
The time required to apply friction element B (a clutch or band inside the automatic transmission) is outside the expected window. Either too long (worn clutch, low pressure) or too short (sticky valve, mis-calibration).
Is it safe to drive with P2701?
Usually safe for short trips, but don’t ignore it: the underlying fault can get more expensive over time.
