Toyota Repair: check engine light, metal particles, cylinder problem

Question
when I had my check engine light checked they said that it was caused by a shift cylinder problem? I took it to the dealership and they said to get my transmission fluid flushed? I just had this done about a year ago. It is a 1999 Camry CE with 162000 miles. I've been that reading a lot of people are having problems with their transmissions and wasn't sure if that is what is awaiting me? Thanks for your help!

Answer
Without knowing the diagnostic trouble codes I can't be of much help, can you let me know what the codes were.
Camrys have had some transmission problems and flushing the fluid may be a waste of money, I would recommend having the transmission oil pan removed and check to see if there are any metal particles in the oil pan, if there are, transmission failure is imminent.
