Transmission lurches when shifting into 3rd. Does that mean transmission going?

What is your question?

Has been happening :gently" for about a year. But happens now in both local and parkway driving. Is much more pronounced and noticeable now than it had been. Does that indicate transmission could go at any time?

How long has your 2000 Toyota Camry had this problem?

Lurching "mildly" for a year; very pronounced for about one month
