Transmission Adaptive Shift Strategy Malfunction
2014-2016 Chevrolet Spark EV Electric Motor 🇨🇦
Description
The transmission adaptive shift learning system has detected conflicting or unreliable data, preventing it from properly adapting shift points and quality.
Symptoms
- Check Engine Light
- Inconsistent shift quality
- Shifts seem random in timing
- Transmission hunting between gears
- Shift firmness varies unpredictably
- Fuel economy fluctuating
Common Causes
- TCM memory corruption
- Conflicting sensor inputs
- Throttle position sensor drift
- Vehicle speed sensor noise
- Recent battery disconnect without relearn
Diagnostic Steps
- Read adaptive shift tables in TCM
- Reset transmission adaptive learning
- Monitor shift quality parameters
- Check throttle and speed sensor accuracy
- Perform transmission relearn drive cycle
Repair Notes
Reset adaptive learning and perform drive cycle relearn. If the issue returns, investigate sensor accuracy. TCM replacement if memory is corrupted.
