That sounds good, I would rather not "shock" the transmission with all new fluid.
 
Good ride; I had a 92 LeSabre that looked as good when I got rid of it (2003) as when it was purchased; Those cars age well on the outside. I burned a valve; At 179K or so, it still hauled.
 
I was able to fix the horn buttons this afternoon as well, reference the pics at the beginning of this thread to see the "before".

OLM reset is under the glove box area. You should see a tiny hole in the black plastic straight down from the glove box latch. use a pen or pencil. press lightly and hold for a few seconds.

I would get all the old fluid out if possible it's not doing you any favors. Ideally you want to do a pan drop 3 times total with 1,000 miles between them but if that's not possible even multiple pan drops or drain and fills if you want to add a drain plug style aftermarket pan can be done every 50-100 miles.

If you can install a new filter do it no and again on the last of the third pan drop. At least that's what I would want.

Obviously even one pan drop is better than nothing, so your choice.
 
Drop the pan. Also get a "red stripe" modulator for the trans, it's $10 and one bolt to change. It'll have a little flathead screw you can turn to your heart's content to adjust the shift quality; a little firmer is better for the trans.

I'm fixing up a 92 Bonneville as we speak.

Sadly in traffic today it looks like a compact.

On a side note, trace the trans lines back to the transmission; i recall GM used a metal guide hanger to hold a metal hose; the hanger eventually sawed thru the transmission line, leaving a big mess; quick fix was hose, hose clamps and a hacksaw.
 
I have never been a Buick fan, but I sure like this cars simplicity for being a luxury vehicle. Looks very clean inside and out.

As mentioned, run her till the wheels fall off.

What a great first car. It's got the best domestic v-6 ever built under the hood,I've seen them get very high 20s on the highway.
theres lots of room for the inevitable pile in with friends who need to go here and there.
The back seat is still big enough,and soft enough to make those quiet evenings with that special someone very special. And the price was right.
With basic maintenance it'll last longer than the engine cradle holding it in. There were a gozillion of those brand engineered variants built and they've proven reliable even under the worst maintenance practices.
Just ignore merks advice in general. He has one though I believe even the car itself feels it's being punished based on his maintenance practices.

He will soon turn 16. So this is his first car.
 
Not sure if you mentioned the mileage on this car but I'd change plugs, wires and fuel filter. Use AC Delco plugs and fuel filter. She'll run like a champ.

115K. Plugs were changed around 80K
 
Nice H-body! Those are excellent highway cars. They ride so cushy. Stick a sticky set of tires on them, and it actually handles okay for such a yacht. Sort of like a dancing bear, those cars can surprise with their limits being higher than they let on.

If you can, get a little fluid transfer pump and a couple of empty gallon milk jugs. Pump out as much fluid as possible through the dipstick, and then drop the pan to change the filter. It's much less messy that way.

Also, plugs and wires likely should be done again. Cheap copper plugs and Autolite wires will work fine for that Series I.

The dash is simple and well organized, almost as though GM were looking at German cars when desgining the dash of this car.
Looks like a nice car.
I hope that your little brother appreciates it and doesn't wreck it.
If he does wreck it, it should protect him and his passengers well.

If the interior looks "dated", its only because it doesn't have an enormous, oddly-shaped center console robbing it of its spaciousness, and covered with various faux brushed-metal surfaces like all new cars these days.
