The method
How the transmission comeback cost is worked out.
A comeback rate is the share of jobs that return for the same complaint. On a rebuild, each one is paid for twice: the labour and parts to do it again, and a bay that cannot take the next paying job while it is done.
- Comebacks a month = rebuilds a month × comeback rate.
- Comeback cost a month = comebacks a month × average cost of a comeback.
- Comeback cost a year = comeback cost a month × 12.
- Share of rebuild revenue = comeback cost ÷ (rebuilds × average ticket).
- Paid rebuilds it equals = comeback cost a year ÷ average ticket.
- Bay-hours to recover = comebacks a month × bay hours a comeback takes × 12.
Stop paying for the same transmission twice.
