Bell 315sj getting into neutral position once you engage number 2 and 4 gear
Welcome to HEF Xolani ! Machine serial number please. Read post #5 here to check your FNR and your solenoids. The procedure should be the same (which is why I need your serial number). Check for wiring damage at the solenoids on the bottom of your transmission (they might be behind a steel protection plate).
