Drive, Intermediate and Low Range - Second Gear: Notes

As vehicle speed increases and operating conditions become appropriate, the TCM de-energizes the reverse, 1st shift solenoid valve assembly (S1) and energizes the 2-3, 3-4 shift solenoid valve assembly (S2) to shift the transmission into Second gear. The manual valve remains in the DRIVE (D) position and line (2) pressure continues to feed the drive (19) fluid circuit.
