Does $132 on labor for a shift solenoid diagnosis sound right?

Getting an engine light for code p0773 for a shift solenoid valve flashing on the dash around 50% of the time...AAMCO is saying that it will take the an hour and a half to diagnose what is wrong with the valve adding to a total of $132 before they even start working on the problem. Does that sound right or is this just another way for them to cash in on their customers? I have a 2001 Toyota Avalon xls
