2000 Buick Lesabre.
At around 120k the transmission was replaced with a used one. Vibration appeared a few YEARS
later. We put on new
tires, balance, alignment. These were needed anyway.

There is a vibration under load (hard acceleration/load is worse).

If you coast at any of these speeds it is NOT present or significantly reduced. Vibration reminds
me of a wheel badly out of balance but seems to be more centered in the driveline.

Another owner recently described a vibration (same year/model w-similar mileage) that may be
the same. Is there anything common to look for on these?

Well, with the amount of miles, and not feeling it for myself, this may be caused by a worn engine mount
transmission mount. A worn mount under heavy load can give what feels like a driveline vibration.

May also be a worn axle
CV joint. These are a little harder to diagnose. Removal of axle and feeling for
loose joint or stiff joint may be required. Also, check for axle being loose as it goes into the trans. This
would indicate a worn bushing in the transmission.

Vibration When Driving My 2000 Buick Lesabre

Question: Is there a fuse to the computer of my 1997 Buick LaSabre and where would it be located at? My car will turn
over but will not crank.

Answer: There are several fuses that power the PCM. That is most likley not your problem. You say it turns over but
wont crank? That is the same thing. What exactly is the car doing?

Had a guy hook up to the computer on the car and he said it would register anything, so could it be a fuse that is blown
to the computer? The car will not start.

Best bet is to check all fuses. There a several and they are not labled PCM or computer.

Where would they be located at on the car?

There is a fuse box under the hood and in the dash.

Where at under the hood? Found the one under dash, don't know where to locate the one under hood.

If i remember, it is a small black cover on the fuse box along one of the fenders.

O.k. Thank You might have to hit u up later. Thanks again, Yvette.
