Drive and Intermediate Range - Third Gear: Notes
WARNING: This page is about a different car, the 2003 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.
As vehicle speed increases and operating conditions become appropriate, the TCM energizes the 3-4, 4-5 shift solenoid valve assembly (S4) to shift the transmission into Third gear. The manual valve remains in the DRIVE (D) position and line (2) pressure continues to feed the drive (19) fluid circuit.
