I Brought my '02 SATURN L300 to trans shop to check transmission due to hard shifting when check engine wrench appears. All goes away & car runs good again after re-started. I have already your previous string regarding this issue & I asked for solenoid check. The codes that came back P0742 & P1811 and the dealer stated it was not the solenoid. Now I'm confused since he suggested that the transmission be replaced for 1800.00. Please advise since I see conflicting information. Much appreciated

Vehicle: 2002 Saturn L300 6 Cyl

Best answer
P0742 Torque convertor clutch (TCC) system - Stuck on

P1811 Maximum adapt and long shift.

These codes set when there is a fluctuation on the line pressure for the transmission.whether it a abnormal high pressure or abnormal low pressure,The dealer can be correct in stating its not the solenoid, Inside the transmission are mechanical componenet that can cause the transmission pressure to go low such as the manual valve,or pressure regulator, It is to your advantage the transmission is replaced rather than a solenoid for the TCC. (P0742).
