2002 Monte Carlo, Chronic problems ?

I am new to this forum.
My 1985 Monte Carlo's transmission is starting to slip and get temporarily stuck in certain gears.
One of the many used cars I am considering buying is the 2002 Monte Carlo.
Does anyone know of any Chronic problems that this car has that I need to be aware of? Is there another year that is more reliabe?
I would greatly appreciate any advice that you can give me.

Thank you,
Clyde Howell
