How many miles are on your vehicle?

Is the transmission fluid full and clean?

66,600 and my fluid levels are good i recently had them check for good measure
Buick Mechanic: Derek Werner, Buick Technician replied 1 year ago

ok great, What has likely happened is the pressure control solenoid inside the transmission is starting to fail. The solenoid controls the Hydraulic line pressure inside the transmission. If the pressure is low it will cause an intermittent harsh shift and set a P1811 fault code. A max adapt and long shift code indicates an excessive time delay between gears when the transmission shifts. If the time is above a specifically programmed amount the code sets.

With the miles that are on your car, it is a very safe bet the internals of the transmission is still ok.

Has the transmission pan been removed and checked for excessive debris? Excessive clutch material or metal in the bottom of the pan will indicate it needs to be rebuilt.

If excessive debris in the pan is not found it is very likely the transmission pressure control solenoid should be replaced, and will fix the concern.

Replacing the PC solenoid or pressure control solenoid is a big job. The side cover known as the valve body cover needs to be removed to replace the solenoid.

Is this something you might try replacing yourself?

No the transmission pan has not been put down i should have done it last week while i was at the shop but i will get this done probably tomorrow. Could you estimate how much it would be to fix the pressure control solenoid? It is an random problem, sometimes it will do it and other time it will hard shift.
Buick Mechanic: Derek Werner, Buick Technician replied 1 year ago

Ya it is a very common problem for your model year of the vehicle, and this code normally will not even turn on the check engine light. Normally the transmission will work for many years with this type of code set.

What happens is the solenoid starts to get worn and will stick, when it sticks you feel the harsh shift like you are describing.

I am looking up the labor time for the job now.

Okay thank you very much sir
Buick Mechanic: Derek Werner, Buick Technician replied 1 year ago

Not a problem, sorry to hear you are having transmission issues but with the low miles i am very certain you will be just fine with replacing the solenoid. The engine in your car is very reliable and should be a good vehicle for a long time.

Labor to replace the solenoid is 4.6 hours. This time, is from ALLDATA. Normal shop rates vary depending where you go. You should expect to pay around 80 to 100 dollars and hour.

The solenoid is cheap it can be found for around 30 to 50 dollars. I would make sure you buy a quality ACDelco part and not an aftermarket solenoid.

What if I was to get this job done at a Midas shop, how much will it cost me?
Buick Mechanic: Derek Werner, Buick Technician replied 1 year ago

Depending on the shop rate and the cost they charge for the part I suspect you will be paying around 500 to 600. I would call around some shops in your area to get a good price.

Honestly, I would stay away from Midas, at least around my area where I live in Montana they are not known for doing great work. A transmission shop would be a good bet since they do this kind of work all the time.
