SOURCE: 95 buick lesabre shifts hard

1. There may be a vacuum leak anywhere under the hood.
2. The vacuum governor mounted on the transmission is broken (has a ruptured diaphragm). Easy to replace, has one bolt and a small (one inch) locking plate.
3. Replacement at AutoZone is around $12~~20.

Hope this helps!

SOURCE: Buick LeSabre makes funny sound!!!

It is a sign of a clogged convertor, but i happen to own the same car (with a series 2 3800) and had the same symtpoms going on when i bought if for the wife. Mine turned out to be a Exhaust Gas Recirculation Valve (EGR Valve).

To kind of get a feel for what is going on with the convertor, you can have someone help you but sitting in the drivers seat, with the car running. You go behind the car near the tail pipe. Now have the other person rev it up a little, not to much though. Put your hand but the tail pipe to see what kind of pressure the exhaust has. You can use another vehical to do the same thing to feel what things are supposed to feel like. If the convertor is plugged, the pressure of exhaust coming out will be a lot softer than it should be.

If after checking it as discribed above, if you feel it is plugged, grab a hammer, and bang the heck out of it. This will break up and loosen the clogged part without have to replace it.

There is no really good way to test a EGR vavle without a special computer. Replacing it however, does seem to me as the most likely repair for this vehical. It is located on the top of the drivers side of the motor. It look like a cylinder with a wire coming out of the cap, and is held on by 2 13mm nuts.

Good Luck....

WILL THE TRANSAXLE MAKE LEFT WHEEL SHAKE AND MAKE THUMPING NOSIE 2001 LESABRE


Have you checked the CVJ? Does it make the noise in a turn or just going straight? You did not say if you had checked the tire for roundness or a bulge which would indicate ply or tread separation.

A delayed clump sound when I put it in reverse


Can you specify what vehicle, standard or automatic? Is the clunk as soon as you shift into reverse or when you press on the gas peddle? If it is when the peddle is pressed then let off does it clunk again? Does the car shake or lunge when it clunks?

Transmission clunks when shifting into reverse after initially starting the car.


It has a worn or broken rear engine mount most of the torque is absorbed in the front mounts and hanger mounts except when it is shifted into reverse.

My 89 buick lesabre will shift into third but engine revs as soon as it shifts acts like it is in neutral , first and second and reverse do fine not slipping , why is it doing this has 140,000 miles


Check the transmission fluid level if it's low, or even over filled it's probably the issue. And also make sure the T-fluid is deep red in color, and no oil or water is in it. Note: Some radiator additive's and treatment's can cause the sill to leak and allow cooling fluid to get in the trans. If your fluid is all good but problem continues let me know and we'll go from here.

1997 Buick LeSabre has squeak noise coming from right front.


More likely this is a wheel bearing or CV joint than suspension components.

One good indication is if, when your making a right turn or accelerating, there is a shudder or shaking in the steering wheel then its likely a wheel bearing.

Another good indicator can be found when you jack up the suspicious wheel. Put one hand on the top of the wheel and one on the bottom and pull back and forth. If the wheel makes a clunking noise and moves in either direction, then wheel bearing is shot.

How do i get to the revers lites in my 1989 buick lasabre


On the side of your transmission will be a switch with several wires coming out of it. This is your reverse switch that turns on your reverse lights and most likely needs to be replaced
