I checked the other posts as far back as my server would go & didn't find
anything like this, so here goes.
I have a 2001 Pontiac Grand Prix, 3.1L V6, with about 75,000 miles on it.
(I bought it used w/ around 50,000 miles on it.) Lately, when I start it
for the first time and put it in drive, it seems to slip in the transmission
(RPM's go up) and then it "slams" into gear. It doesn't do this with any
gear other than first, and it doesn't seem to happen any more during the day
(yet). I don't know if the former owner ever changed the transmission fluid
/ filter. I'm planning to take it in for a few other fixes, so I'll get
them to do that, too. Any ideas why it does this, and what to do to fix it?
