Question

My check engine light just came on and now it's shifting werid into 2nd. I got the code read at auto zone but they couldn't tell me what it meant

Answer 1

P1750 Solenoid assembly malfunction

Lexus does not use this code, that why there no code definition for it, this does not mean the code recieved is not valid  if the transmission is shift weird  into 2nd gear this is a internal mechanical condition with the transmission. You can remove the transmission pan if there is heavy sediment in the transmission you would need a transmission rebuild.
