What does code P1811?
A P1811 diagnostic trouble code means the hydraulic line pressure has been raised to compensate for excessively worn clutches or other components. If left unchecked, this excessive line pressure can cause serious damage to other control components, making a small problem a lot worse.
What is the p1811 code for GM front wheel drive?
The P1811 code is one of the most common codes for transmissions in 1997-on GM front wheel drive vehicles. Symptoms of this code include a check engine light illuminated and harsh shifting. Cycling the key on and off may cure the harsh shifting until the criteria for the code is met once more.
What happens when p1811 is set on peoples transmission?
The PCM will also command the check engine light or service engine soon light to be illuminated when P1811 is set. Basically, the PCM is sensing a slip, and is increasing line pressure to maximum in order to prevent the transmission from hurting itself further.
What causes code p1811 to set and repair options?
Cycling the key on and off may cure the harsh shifting until the criteria for the code is met once more. We are going to cover what causes the code to set and repair options. If a shift into any gear other than reverse and forward engagements takes longer than 0.65 seconds to complete, code P1811 will set.

What does p1811 mean in Powertrain Control Module?
With the engine running and an adaptable shift has occurred, the Powertrain Control Module ( PCM) detects during the following conditions occurred twice per trip: Condition 1: 1-2 Shift over 0.65 seconds and 1 -2 Shift adaptive reached its limit. Case 2: 2-3 Shift over 0.65 seconds and 2-3 Shift adaptive reached its limit.
