You will need to refer to the service manual for your vehicle to see which pattern maps to Normal, A, B.

From what I've been able to gather, normal shift is when the shifter is in D, pattern A is when the shifter is in M, and pattern B is tow/haul on trucks or sport mode in cars. No guarantees this is correct.
