HKS ALC II for sale. Just did a 5 speed transmission swap into my Z so I no longer need the ALC. It did work perfect for me while I had my auto though. Never put many miles on it because the car became pretty much a show and summer time only car.
Description: HKS’ ALC (Automatic Line Controller) is a plug-in interface for OEM computer controlled automatic transmissions in the '90-'96 Nissan 300ZX that maintains constant line pressure, ensuring consistent and precise high performance shifting. Should the pressure begin to drop within the transmission, the ALC will signal the factory A/T Control Unit to increase line pressure and maintain it at the correct level.
