2013 Lexus RX 350 - P2714 SLT Solenoid Performance and Harsh Shifting

Question

The transmission has started shifting very hard from 2nd to 3rd gear and occasionally slips into neutral when coming to a stop. I hooked up my Techstream and found P2714 stored in the TCM. The oil level seems fine but it looks a bit darker than I like to see.

Fixed it by replacing the SLT Pressure Control Solenoid (Part #35290-45010) and the internal strainer. Upon dropping the pan, I found the SLT solenoid screen was partially clogged with debris. Replaced the solenoid, torqued the valve body bolts to 10 N-m, installed a new filter, and performed the 'Transmission Reset' in Techstream. Total cost was about $240 and it's shifting like new again.

If the fluid is dark, you might have a sticking valve in the valve body rather than an electrical failure of the solenoid itself. Try a drain and fill first with Toyota WS fluid, but do not flush a high-mileage U660E/F transmission.

Could be the ECM. Some of these 2010-2015 Lexuses had software issues where the line pressure calculation gets wonky. Check if there is a TSB for a calibration update for your VIN.

P2714 usually points to the SLT solenoid which controls line pressure. I would check the resistance of the solenoid at the 10-pin connector before dropping the pan; should be between 5.0 and 5.6 ohms.
