Auto tranny. Any know problems?

Wondering how well the Auto trannys hold up in say, early 90s pickups. I've owned older toyotas but they were manual. Anybody had any or know of any cronic problems. Thanks

I had an 89 x-cab longbed toyota with an auto tranny and it worked fine.Never had any trouble with it.It had about 150k on it when I sold it,and has over 225k on it now,and tranny still works good.
