Hello all I got an 02 Saturn l300 v6 automatic trans code p1811 long shift my question is how many solenoids are there? Does just this one control 1-2 shift and 3-4 or are there 2 different pressure solenoids I need to get thank you

 

There are several solenoids in this transmission. The pressure control solenoid failure is common across many car makes and models. There are also shift control solenoids that control the different gear combinations. I purchase automatic transmission parts from transmissionpartsUsa.com. There are several online transmission parts suppliers.
