P0700 is a transmission-related trouble code. Below are the specific causes of this malfunction: 1. Insufficient gear oil level or poor-quality gear oil. 2. Severe wear on gear tooth surfaces, resulting in excessive meshing clearance. 3. Fatigue spalling or chipping of gear teeth edges. 4. Excessive wear on the intermediate shaft or secondary shaft, or severe wear on spline shafts and internal gear splines, leading to excessive clearance. 5. Bent shafts or loose shaft locking components. 6. Loose bearings or damaged bearing cages. 7. Non-working parts of shift forks making contact or rubbing. Note: When the P0700 trouble code appears, the vehicle should be promptly taken to an auto repair shop for servicing to avoid accidents.
