The pressure control solenoid generally is the culprit from P1811 code.
I know it is labor intensive to access or replace the PCS and best to replace it.
Dropping the trans oil pan however is easy/ to install the shift kit into the accumulator.
The P1811 code is gone and no more harsh shifts so far. Can it break something in future?
Even if I get another 60 k miles out of it I will be happy.
