“Last week my 2007 Camry’s transmission went out.”
You might want to say what that means. The transmission isn’t “a” thing but a whole bunch of things.
In addition to that most auto shops are not a place to go if you have transmission problems. This includes even a lot of dealer service departments. Automatic transmissions are a specialty. Not only is it a bad idea to ask a general mechanic for an evaluation of an auto trans, but its also a bad idea to take one to one of the many transmission chain-type operations.
Yes - if you do mostly highway miles, 131K is not unheard of, but is not all that normal. So lay out the details, including what the transmission is doing, where it was diagnosed and as many details as you can muster about the diagnosis (including computer generated error codes).
Also, following recommended maintenance schedules for transmissions is often a bad idea, so provide details, as in “X was done to the transmission at xx miles by [kind of shop]”
