Find a mechanic with a scanner that can access the Electronic Automatic Transmission Controller, (EATX), (Transmission Computer) to read any stored diagnostic trouble codes. Those codes are a starting point and will identify the circuit or system with the problem, not necessarily the defective part.
The scanner will also read out four numbers called the "clutch volume index" (CVI) for electronically-controlled transmissions. That is the volume of fluid, in ccs, it takes to apply each clutch pack. An experienced transmission specialist will know from those numbers how much wear has taken place in the clutch plates.
