Buick Lesabre owners have reported 9 problems related to transmission solenoid (under the power train category).
Within the passed 2 months I have been experiencing "hard shifts". Very pronounced jolt/jerk when accelerating after a full stop or decelerating to come to a stop. Just researched on this site and found many other consumers with 2004 Lesabre's experiencing same situation. Has to do with inferior pressure control solenoid and/or shift solenoids. Apparently gm has refused to recall and replace due to the cost. Can cause premature failure of transmission and they say they are under no obligation to make it right!!! also have had problems with speedometer and tachcometer. My tach is frozen at 2 and speedometer started giving false readings about 3 yrs. Ago. Did not address because my mechanic told me its very costly. I have to use my garmin to tell me how fast I am going. Happened first time in extreme heat traveling on highway. Then again when it w as raining. Very unsafe situation and again a very costly fix that gm will not address.

Very common know problem of the 4t65e transmission equipped in these cars is a pressure control solenoid and/or the shift solenoids fail prematurely due to a poorly constructed parts. A service bulletin has been issued by manufacturer warning of the problem and to use a much more superior part to replace the bad ones. This happens across a number of vehicles and gm refuses to recall said part even after knowing it is a failed part. The problem it causes is the transmission goes into high pressure mode and causes hard up shifts. There is a unofficial work around that involves installing after market parts to stop the hard shifts. Gm has been made aware of the problem and has personally told me they will not issue a recall due to cost of recalling and repairing. Especially in cars that this has caused premature failure of the transmission. And they say they are under no obligation to do so. The sad thing is I just asked for the updated part so I could personally install it because I do better work than their garages and wouldn't trust them to change a tire let alone touch a transmission. I am capable of installing the parts I just want the updated one for free since it is a problem that should have been corrected on their part to begin with. This problem is much like the coolant problem gm claims didn't exist until they were sued for it.
2000 Buick Lesabre developed problems with shifting properly. The p/c solenoid switch failed which caused the vehicle to shift erratically while being driven. The consumer contacted the manufacturer about this problem but the since the vehicle was out of warranty they provided no financial assistance.

Transmission failure, causing hard shifts and shuddering when driving. Gm has a TSB out for this sympton but denies any problem with the transmission. Dealership tech confirmed with diagnostic test and refered to bullitin #00-07-30-002b pressure control solenoid valve assembly. Gm refuses to pay for even a portion of the repairs inspite of their TSB indicating a problem with this perticular make and model. The vehicle was purchased used from my father inlaw with 81k miles on it. 12/26/04 and was very well maintained. Iif they issue a TSB for this specific problem, they should take some responsibility iin corrective repairs as laid out in their own TSB. Gm refuses to own up to this problem.
The contact stated the indicator light on the dashboard for the transmission illuminated. The vehicle has been to the dealer, and they completed a diagnostic test which showed transmission slippage. The dealer replaced two solenoid valves. The indicator light was working properly. The vehicle would not pass emissions testing with this light illuminating.

Transmission problems involving 2001 Buick Lesabre. The vehicle experienced sudden acceleration. This occurred while backing out of parking spaces and at traffic lights. The cruise control had become inoperative. The solenoid valve was replaced in the transmission, however it did not resolved the problem.

When the consumer attempted to apply the gas, the vehicle vibrated. The dealer was notified. The consumer knew of other Buicks with the same problem. There was shuddering in the transaxle (transmission) and required replacing the solenoid assembly. Gm was unwilling to resolve the problem.

2001 Buick Lesabre limited that had a solenoid in the transmission fail** the pressure control solenoid in the ransmission failed.
While making a sudden stop, consumer noticed driver's seat moved forward while turning corners. Consumer heard a popping noise, seat moving side to side. Dealer has been contacted. The automatic transmission has a harsh down shift when merging on to a freeway or goind up a hill. Shifts down to lower gear. The solenoid was replaced and the powertrain control module was updated but did not correct the harsh engagement. Once in a while the harsh engagement happens when going from drive to reverse. The transmission fluid was flushed due to sediment. The rear brakes still moan and are squeaky at low speeds. They were hosed off to remove the excess brake dust form the rotors. The brakes pulsate when braking hard on freeways or city streets. The steering labors engine when turning a corner or backing up. The power steering hydraulic hoses were replaced.
