OK guys I got in my 1997 lexus SC400 this morning and started it to let oit warm up. It though a CEL. After work today I pulled the codes and I got "P1755" and "P1765" both were listed as "manufacturer control tansimission". The fluidlevel in the transmission is perfect and the fluid looked good and clean. I havent had any problems with the car shifting at all and driving perfromance has been fine.

Does anyone know what this could be or what I need to do?

 

searching netted me this

P1755 linear solenoid for lock up control circiut malfuntion.

P1765 linear shift solenoid circiut malfunction

P1755 i have no idea about and P1765 i would imagine i would have shifting issues. Most people with this error seem to say something about solenoid #4 and not being able to shift at all or not having over drive

I believe i have a malfunctioning overdrive solenoid. Further searching mentions that P1765 being thrown if the shift solenoid valve "SLN" is malfunction. I really am stumped cause the cause seems to be working just fine.Shifting is smooth and fine and I can feel the shift from1-2 2-3 and then 3-4. Is there a shift i am missing?

 

Did you ever get it fixed? my car just gave me those two codes
