P0701 - Transmission Control System Range/Performance
Transmission control system reported a performance or range problem.
Treat the code as the starting point: compare symptoms, likely causes, and repair paths before pricing parts or moving into an estimate.
Code Overview
Transmission control system reported a performance or range problem.
Common Causes
- Low or dirty fluid
- Internal transmission issue
- Control solenoid fault
- Sensor input problem
Diagnostic Steps
- Check fluid level and condition first
- Scan for transmission-specific companion codes
- Note shift quality and fail-safe behavior
Likely Repairs & Cost Guides
Use symptoms, scan data, and quick checks to confirm the likely repair path before pricing parts. The estimator helps compare repair paths before replacing anything unnecessarily.

Browse nearby code-family pages when the same fault pattern overlaps across systems, such as misfire, lean fuel trim, EVAP sealing, cooling, or charging faults.
Next Steps
Move from code lookup to diagnosis, then estimate the likely repair only after symptoms, causes, and checks point to the same path.
