94/95's had the 4R70W, not the AOD.
And disregard Jason - I've had my 90 5spd for a year without any problems with it and have driven it daily. If the car has been built, and was done right, it should last quite a while.
Things I'd watch out for - harmonic balancer and headgaskets. Those seem to be the 2 biggest problems for the cars. I would think being as far as south as you are, rust wouldn't be a big problem like it is up here.
