The highest range you have Ian is 2MΩ but you're extremely unlikely to need that in automotive fault finding! Any reading in the megohm range will suggest an open, or break in the path you're measuring.
For continuity checks, use the 200Ω range. You're looking for a reading very close to zero. Remember that when measuring resistance, the car battery should be disconnected and the circuit you are measuring should be broken. In other words, when checking the resistance of the automatic gearbox solenoid valves, the connector must be separated first.
