2001 Buick LeSabre auto transmission shifting hard sometimes

I was leaking antifreeze into my oil and mechanic changed the gaskets. Since then the transmission is shifting hard sometimes, worse once it's warmed up. Some improvement with Sea Foam. I have been told it may be the torque converter, electronics, or the transmission is going out. 189k miles on this car. Car misses sometimes at an idle.

2001 buick lesabre won't shift into overdrive


Even good mechanics make mistakes. I'd take the car back to the mechanic who changed the oil and tell him the problem, and ask if he'll check to see if he knocked a connection loose. If he gives you a hard time, take it somewhere else. As you guessed, it's probably just a loose or disconnected wire to the transmission.

My 2001 Buick LaSabre "eats"


If there are no coolant leaks then check your engine oil to be sure it is not over full or foamy because if there is coolant getting into the oil it will cause irreversible damage to the engine. If the engine has ever over heated the head gasket/s could also be leaking and will need replaced.

Bad transmission leak, steady, 1/2 qt. overnight?


The most probable cause of a leak that steady would be the transmission oil pan gasket. It is an easy fix and I would also recommend changing the transmission filter when you change the gasket. Hope this helps!

My check engine light is on and the car is idleing hard i smell antifreeze and the transmission fluid was a littlelow


I suggest having a full service tune up performed.

oil change (filter / gasket)

tranny fluid (filter / gasket)

spark plugs, wires, cap and rotor replaced

O2 sensors replaced

Have the thermostat replaced, radiator checked for leaks, and repalce both top and bottom radiator hoses.

Have a full diagonstics test performed as well to bring up any codes that will show other issues.

Let me know if you need further assistance.

1997 buick lesabre 130,000 miles auto. goes into drive fine and rev. but when driving it it wont shift the moter races and wont shift like it stayes only in 1st


Check the transmission fluid and see if it's low on fluid. If it is more than one pint low it could cause slippage, With that many miles if you have not done a transmission oil and filter change then you will need to do this first when they pull the pan they can tell if you need to overhaul the transmission. Hope this helps you. The cost for a transmission oil and filter change ranges from $150.00 to $200.00.

I have a 1998 Buick Lesabre that keeps losing antifreeze.


Buick 3.8's are notorious for intake manifold leaks. If you are sure you are not leaking externally (look under the alternator and on the top of the transmission), it could be an intake manifold leak. I've replaced mine...I didn't think it was too hard a job for an amateur.
It could also be a head gasket, but the intake leaks are much more common.

Sometimes the transmission on my 2001 LeSabre 3.8 V-6 shifts hard but not always tranny has been serviced with new filter and fluid


Have someone check for any transmission codes these don't always turn on your check engine light,If no codes and your speed sensors are reading ok it sounds like you may have a accumaltor piston seal may be leaking.

2001 buick lesabre, transmission problem?


There is a pressure sol. in the transmission that is bad . This is a common problem that requires removal of the side transmission cover. The transmission does not need to be rebuilt! Talk to a gm dealer. I have sold over a hundred of these pressure sol. and the side cover gaskets to a real gm transmission mechanic that have fixed this problem. GM parts over 20 years.

2003 BUICK REGAL TRANSMISSION PROBLEM.


This is a common problem on some GM cars. There is a pressure control valve in the side cover of the transmission that needs to be replaced. The transmission does not have to be rebuilt. You will need to get a side cover gasket also.
