The original scale of spares lists transmissions at 4 per 100 vehicles per 12 months so on first glance the plan of 1 spare for 3 trucks seems a bit cautious. On the other hand, what good is less than a complete transmission if the plan is to be able to replace the assembly?
Another way to look at is that you are going to hold an 8 year stock (if my math is good) on a scale designed for service driving, use and abuse....... and much longer on your kinder driving, lower mileage and better maintainance program. You should be good for life.
