Lexus Troubleshooting Questions? Ask a Lexus Expert
have you scanned for codes?
sorry had a storm and my internet was interrupted...do you have a code reader/scan tool
give me a few
b1826 is a seat belt issue...
c1201 is shutting off the vsc system due to engine codes
po746 is a shift solenoid or valve body issue
DTC P0796 Pressure Control Solenoid "C" Performance (Shift Solenoid Valve SL3)SYSTEM DESCRIPTIONThe TCM uses the vehicle speed signal to determine the actual gear position (1st, 2nd, 3rd, 4th, 5th or 6th gear).Then the TCM compares the actual gear with the shift schedule in the TCM memory to detect shift solenoid valves and valve body mechanical problems.DTC P2714 Pressure Control Solenoid "D" Performance (Shift Solenoid Valve SLT)SYSTEM DESCRIPTIONThe linear solenoid valve (SLT) controls the transmission line pressure for smooth transmission operation based on signals from the throttle position sensor and the vehicle speed sensor. The TCM adjusts the duty ratio (*) of the SLT solenoid valve to control hydraulic line pressure coming from the primary regulator valve. Appropriate line pressure assures smooth shifting with varying engine outputs.(*): Duty RatioThe duty ratio is the ratio of the period of continuity in one cycle. For example, if A is the period of continuity in one cycle, and B is the period of non-continuity, thenDuty Ratio = A/(A + B) x 100 (%)
usually shift solenoids and a valve body replacement.. so basically the transmisson needs to be opened up to repair
hope you can rate my service 5 star
