The transmission pressure control solenoid may fail causing erratic shifting. Our technicians tell us that partial dis-assembly of the transmission is necessary to replace a failed pressure control solenoid.

hard shifting after driving long on long trips,after key is turned off and back on it shifts normal.
would lose all gears after 10 minutes of driving; yet wait 3-4 minutes, and car would drive shifting again for 5 minutes, and then the transmission would stop again; it would go on like this for at least a hour, then I was back home and parked, now what??
Car won't shift acts like it has no power and gets really bad gas
same problem as everyone else shift solenoid gone bad. if you turn car off for a few minutes and restart problem will go away for a little while but will come back.my car has had this problem for over a year at about 150,000 or so i now have over 205,000 on it and still running fine. just that nuisance clinking ever so often but nothing I am going to pay 2500 to fix. car is 9 yrs old that 2500 when I do decide to spend it is going on a new car not in this on besides it only happens very seldom so I can live with it.
A little while ago my car would have the check engine light come on then go off. Now when the check engine light comes on, the transmission will not shift into overdrive and if you want to creep forward and tap the accelerator the car will sputter and almost die. It's actually died twice. I have no idea as to whats wrong with this darn thing.
Same problem as others are having. Around 70,000 miles on a trip it started to shift hard and whine. I took it to a garage and $830.00 later they said the solenoid was bad. Not even 3,000 miles later it started the same thing again. I refuse to pay another $800 plus dollars to fix a problem that GM should have fixed right the first time. I plan on not to purchase any other Buicks nor will my family members.
HARD SHIFTING BETWEEN GEARS. I HAVE TO STOP AND SHUT THE ENGINE OFF FOR ABOUT 3 - 5 MINUTES. THE PROBLEM SEEMS TO GO AWAY AFTER THAT UNTIL NEXT TIME. THE PROBLEM CAN RETURN IN DAYS, WEEKS, OR EVEN MONTHS. I'M SURE IT WILL GET WORSE WITH TIME AND WILL HAVE TO BE FIXED. I'VE BEEN TOLD ITS THE TRANSMISSION PRESSURE CONTROL SOLENOID. OTHER THAN THAT THE CAR RUNS AND LOOKS ALMOST LIKE NEW. PEOPLE CAN'T BELIEVE ITS 15 YEARS OLD!
I have a 2001 Buick Park Avenue Ultra with 115,000 miles and for the last 5,000 miles the transmission has been shifting roughly intermittently. Sometimes it is fine and sometimes the shifting is rough. Last week I drove it about 40 miles to a golf course and in the stop and go traffic the shifting was rough. After playing golf for 5 hours I drove back the same way and there were no problems and the shifting was smooth. I had the transmission serviced at 107,000 miles and after that is when the shifting problems began. I had the transmission serviced again at 110,000 and this helped until now at 115,000 miles. Reading all the reports, it seems that the power control solenoid PCS needs to be replaced.
I have the erratic shifting but have not had the problem fixed yet.
Bought it w/ 88k mi. now @ 110k, have had regular oil changes @ 3k intervals and have read elsewhere of the same problem. There's a hitch in her giddyup, lots of lurching when it's trying to shift and then the check engine light comes on, then goes off and it runs fine. Recently had the codes read: PO742 TCC CKT stuck on and PO481 Cooling Fan 2 Ctrl CKT Malfunction. AAAAARRRRGGGHHH. Should this have been recalled along time ago ... .
Same problem for my 01 Century. On and off hard shifting, especially at stop and go traffic.
Had the solenoid replaced at a cost of $800. Within a few months the problem with the erratic shifting started again. Took the car back to the repair place (Christian Brothers) said the diagnostic code was different and said that the car needed a valve body replacement. Had this repair at A+ Transmission at a cost of $1075. Now a year later, but with less than 30,000 miles on the car, the car is shifting roughly again, and a diagnostic check said the torque converter switch is stuck to "on". Planning to take it to another transmission shop for a second opinion. This apparently is a habitual problem from other reports I've read.
2004 Buick Century won't accelerate and th check engine light is on. Sometimes the engine won't turn over causing it not to start. After a while, the car cranks and drives OK but there is skipping and then the acceleration problems start.
transmission sometimesshfts hard
SOME DAYS IT SHIFTS HARD OTHER DAYS FINE
My transmission shifts hard. When I took it to the mechanic, they told me it would be $2500 or more to take it apart and fix it... I figured I might as well pay for a used transmission that would be cheaper and swap it out...
The transmision will not down shift unless you come to a complete every time you approach a stop sign It does not happen all the time
When ive been driving around town for a while it will begin to jerk when upshifting also jerks going from Drive to reverse and reverse to drive a very delayed jerk.
Hard shifting after 20 minutes of city driving. Seems to occur less frequently on cold days.
Car shifts gears while driving. Slows down. Sticks in gear.
