Yeah the 4T65 and the 3800SC is not a good match.

I bought my 99 GTP with 37K miles, first trans at ~44K miles ( no clue on PO care)

I am now at 127K car runs great, trans seems good too. most of the mileage was work commute (65 miles a day on the highway @ 65-70MPH).

Now I drive 8 miles.

As Dominic said, yeah the 3800SC have gasket issues. I have replaced (mostly under warranty0 the following gaskets:
Valve covers
intake manifold
Oil Pan
Rear main
Timing Cover
front seal

installed new plugs and wires at 96K. replaced the Power steering pump and the ABS ECM (bought a good used one)

Car has been good though, I expect another 30K out of it I hope
