PM me if interested The HKS ALC has been developed as a plug-in interface with factory A/T Control Unit of the computer controlled automatic transmission on the ‘90-’96 Nissan 300ZX. The ALC is designed to maintain constant line pressure within the transmission for consistent, crisp 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 that level. In most cases, it'll even make your auto transmission last longer. No tuning required and takes less than 10 minutes to install. It's one of the best performance mods you can do to an auto Z. This unit basically does the same as getting your valve body mod done.
