INTRODUCTION NISSAN RL4F03A - RL4F03V The RL4F03A and RL4F03V are found in the Nissan Sentra and NX Coupe vehicles. These units are hydraulically controlled and have two solenoids, one for torque converter clutch and the other for overdrive cancel. Even though these units look similar, there are significant differences in the internal geartrain. The number of clutches will also vary between the different clutch packs. The biggest difference between the units is the viscous coupling in the final drive. The viscous coupling is found in the F03V (Viscous) transaxle.
