Transmission slipping on your 2017 Nissan Pathfinder with code P0700 indicates the transmission control module has detected a malfunction. While P0700 is a generic code, it signals that other, more specific transmission codes are stored that identify the actual problem.
Understanding P0700
Code P0700 is a generic transmission code that essentially means 'check for other transmission codes.' It doesn't identify the specific problem but alerts that the transmission system has detected an issue. Additional codes stored in the transmission control module reveal the actual fault.
Pathfinder CVT System
The 2017 Pathfinder uses a CVT that simulates traditional gear ratios. When it 'slips between gears,' the CVT belt is actually slipping against the pulleys during ratio changes. This can feel like losing power, RPM rising without acceleration, or hesitation during speed changes.
Common CVT Issues
Slipping in the Pathfinder CVT typically results from degraded CVT fluid losing friction properties, worn belt or pulley surfaces, internal valve body pressure issues, failing torque converter, and software needing updates. The CVT is sensitive to fluid condition and service intervals.
Diagnostic Process
Use a scan tool capable of reading CVT-specific codes, not just generic OBD-II codes. Check CVT fluid level and condition. Verify correct NS-3 fluid was used in any previous service. Check for technical service bulletins and warranty extensions for your VIN. Have a transmission specialist evaluate internal condition.
Repair Options
Options range from fluid change with proper NS-3 fluid, to valve body service, to complete CVT replacement. Check extended warranty coverage as Nissan has programs for CVT issues. Given repair costs ($3,000-5,000+), verify diagnosis before committing to major repair.
