What is code 1811


Your PCM has the means to adjust shift pressures and timing to make all the shifts smooth but properly timed. This code means that the computer cannot adjust any more because of an issue. This could be a pressure control issue or possibly a leak at a clutch seal. I would talk to a reputable transmission shop and see what they have to say. Chances are that you will need transmission repairs.

Code 1811 chevy impala


Hi there:
A common problem with the 4T65E autotransaxle is the pressure control solenoid (PCS) causing the hard shifting and in most cases upshifts only. If this is the case with yours then a scan with a trans capable scan tool may reveal a stored DTC of P1811 (max adapt, long shift) which would confirm the PCS (Pressure Control Solenoid) s suspect.



Checkn in THIS LINK description and test procedure.

2004 impala jerks into first gear sometimes. steering wheel whines. I had transmission flushed. Is the tranny going out. I read many reviews that says it is Thanks


The 2 aren't connected to each other. Tranny flushes are NEVER good. Have it checked for codes. Code 1811 (EPC) VERY common in those trannys cause hard shifts.

Especially when the car is cold, the car jerks when shifting from first to second gear. When sitting at a light and then pressing the gas to go, the car hesitates before it moves.


Sounds like 2 different problems. Have san done if code 1811 comes up that is EPC in the trans. Other problem could be mass airflow sensor.

I switched my stock radio out of my 2001 Chevy Impala because it was defective and replaced it with a used radio I got from the junkyard. I called Chevy to see if I could get the code to unlock it and they told me I had to go to a Chevy dealership which I did. Cost $40.
