Nissan Pathfinder · 2022–2025
The redesigned 2022+ Pathfinder switched from the CVT to a ZF-based 9-speed automatic, and many owners reported harsh 1-2 or 2-3 shifts, lurching at low speed, hesitation when selecting Drive or Reverse, and occasional banging into gear. Nissan issued service information and software updates addressing shift quality and transmission control behavior, indicating this is a recognized field issue rather than isolated driver perception. Complaints commonly describe the problem as most noticeable when cold, in stop-and-go traffic, or during parking maneuvers.
Common Symptoms
- harsh 1-2 or 2-3 upshift
- bang or thump when shifting into Drive or Reverse
- hesitation before moving from a stop
- surging or lurching at low speed
- rough downshifts when slowing
- worse behavior when cold
How to Fix
Diagnosis typically starts with checking for TCM/ECM calibration updates, confirming fluid level/condition, and performing the prescribed adaptation or relearn procedure. Many vehicles improve with updated transmission software, but persistent cases may require valve body/mechatronic inspection or transmission replacement if internal faults are present. Road testing under the same temperature and load conditions that trigger the complaint is important because some units behave normally once warm.

Frequently asked questions
What does P07A5 mean?
P07A5 stands for "Transmission Friction Element "B" Stuck On." This code sets when the transmission control module detects that friction element B (a clutch, band, or multi-disc pack) stays engaged when it was commanded to release. Because friction elements must apply and release in sequence to shift gears, one stuck on can tie up the transmission or cause harsh, incorrect shifts. Symptoms include harsh shifting, slipping, binding, or the transmission going into failsafe mode. This usually indicates an internal hydraulic or mechanical fault.
What are the most common causes of P07A5?
The most common causes of P07A5 are: Stuck or damaged friction element (clutch/band) B, Stuck pressure control or shift solenoid, Debris or contamination in the valve body, Low or degraded transmission fluid, Internal valve body wear or sticking valves, Mechanical wear inside the transmission, Faulty transmission control module (less common). The specific cause varies by vehicle.
