Is "stance" important?

I picked up a Crown Vic DD with only 55K on the clock for $2500US, and I noticed it did not shift right with the A/C on. Went ahead and changed out the fluid and filter twice, and it seemed just okay until 130K when third and fourth started slipping to where it needed to have some diagnostics and replacement therapy. Since I am neither a blue oval or trans guy, it only came out to where it functions. Wish I cared more, especially after the plastic intake failed. Luckily they sell entire kits with alloy manifolds for only $130US...
