A/T Control Solenoid Valves

On 3.2TL and 3.5RL, various engine sensor inputs to the PCM are used to control the A/T shift control and torque converter lock-up control solenoid valves. This provides precise timing for the gear shifts and torque converter lock-up system. On Integra, Transmission Control Module (TCM) controls shift solenoids and torque converter lock-up solenoids.
