Hello. My name is Tan.
Could I get engine serial number please?
Is the gear lube monitor for the drive full of gear oil?
Does the engine shift hard or stall going in or out of gear?
The only thing that will give intermittent alarm is failing sensor, low gear lube.
Now in this statement you say "It does not shift hard no stall going into or out of gear." Then in the next sentence "Just what is explained above with going to neutral it sometimes alarms and stalls"
The stalling is caused by the shift interupt switch. Going in to neutral is coming out of for or rev.
If you pull engine out of gear slowly it can stall the engine. When engine stalls it will sound the alarm as you loose oil presure as it turning the key off.
When shifting these engine you have to be positive going into and out of gear. If you ease into gear it can cause stalling and it you pull out of gear slowly it will stall the engine. The shift should be quick. This is the only thing that will cause your issue other than a bad shaft cable.
The reason the alarm sounds is when you shift slowly the interupt switch actually kills the ignition momentarily. If slow shifting it will allow the switch to stay engaged to long causing the stall of engine and the alarm to sound.
