In defining a good (or bad) customer, you need to determine the factors that matter to your company. It is important to consider and evaluate the specific factors that impact your business, and how it should view its customers.
Jim Dial discusses the importance of understanding hydraulics when working with transmissions.

A 2014 Nissan Versa arrives at a shop on a flatbed with a customer complaint of a loss of engine power. The reason it was brought to a transmission shop is the type of engine power loss it had. In park or neutral, the engine can rev up to 2500 rpm easily. Even in drive with the brakes applied, you can reach stall speed torque with no power loss issues at all. But, the moment the brake is released to launch forward, as soon as it starts to roll there is an immediate loss of engine power.

This is not the first time for these two companies, but it may be their most complicated partnership yet.
