We wish to thank Nissan Corporationfor the information and illustrationsthat have made this booklet possible.

The RL4R01A transmission is a hydraulic controlled unit, that is similar to the RE4R01A electronic controlled unit. Although there are similarities in the internal components, the valve bodies, cases and housings have differences. This unit is found in trucks.
