The transmission on my 2000 Buick Century has a hard shift condition that was diagnosed at 2 different transmission shops as a pressure control solenoid failure that is very common with this car. One of the shops said the problem will reoccur even with replacement of the part unless a shift kit is installed. After researching this issue on line it becomes apparent that the shops are correct in their diagnosis. Why has this issue not been a recall!.

I have a 2000 Buick Century limited and the transmission harsh shift 1234, when hot and sometimes cold, I know that it needs a new 1234 up shift solenoid and to be inspected for failed parts etc, also the odometer,fuel gauge,and window regulators/motors have failed, the odometer is out and fuel gauge floats and windows have failed due to bad design of motors/regulators and my airbag light is on and each 4t65- e trans and many Buick trans like the one above has harsh shift and could cause damage and cause trans to fail. And the problems above will be found in many Buick Century and gm should fix the issues above for free it is a danger for the trans to fail and odometer/gear shift select to fail because most people will not know what gear they are in, and the trans could lock and cause a wreck or a huge injury or worst. And the trans 1234 up shift pressure control solenoid not keeping the right pressure could damage the trans, and even if the trans is bought used it still has this problem and is the same 4t65-e trans and gm needs to fix this for free there are many complaints and issue with the 2000 Buick Century,regals etc with this type of trans. And should be fixed right away before it becomes a costly repair or wreck! and the trans should be checked for any other failures. For free.
