Field a is gearbox litres. Field b is the price per litre. The labour field is the service line. 4 and 65 with labour 250 give 510. The examples add 250, 0, or 300.
ATF and a manual box do not load as separate lines. You type 65 yourself. Another labour figure at 4 and 65 gives another result than 510. The calculator does not know a dealer.
