Replaced both transmission lines to the radiator.
I haven't had any problems with this car except for the transmission lines that I replaced (both for about 25-30 dollars, had to buy them from a dealer).
The car is surprisingly quick for a big car with a small V-6.
I love it, and dread the day I have to sell it, they'll have to pry my hands off of the steering wheel.
No little V-6 there, that thing is a work of art. First came the Quad-4 160 horse 4-cyl in the Grand Ams, then this hoss of a 6, and from it was designed the Northstar V-8. That "little" 6 is really a "little 8". I haven't had any V-8's run with mine yet that weren't drag-ready or tweaked in some way. Ate a Thunderbird SC just a couple days ago =-)
