P2757 means the converter clutch was commanded to apply, yet the speed difference between engine and turbine stayed too large, so the lockup never really happened. It is a functional verdict: the circuit may be electrically sound while the valve, the hydraulic feed or the clutch lining fails to deliver. Toyota uses it on the 2014–2019 Corolla CVT, where it points to shift solenoid SL; bulletin T-SB-0150-16 replaces the valve body. On 2016 Ram 3500 to 5500 trucks with the Aisin AS69RC six-speed, bulletin 21-027-16 traces it to a dislodged snap ring inside the converter, and an FCA tech tip notes the code returns during a light-throttle lockup attempt. Expect higher revs at cruise, more fuel use and hotter fluid.
Medium severity. Can I keep driving?Drive as little as possible and gently. If the transmission slips or stays in one gear, go slowly to a repair shop or call for a tow truck.
Symptoms
- Engine speed stays high at steady cruise
- Higher fuel consumption
- Transmission fluid runs hot
- Check engine lamp on
Most likely causes
- Sticking lockup solenoid or valve body (Toyota CVT solenoid SL)
- Internal converter fault such as a dislodged snap ring (Ram AS69RC)
- Low, aged or contaminated fluid
- Worn converter clutch lining
What to check, in order
