P1810 - TFP (Transmission Fluid Pressure) Valve Position Switch Circuit This indicates that you either have a fluid problem - not enough or bad fluid, or a sensor problem. The sensor is located under the tranny side cover assembly next to the valve body, which is major work.
P1810: Transmission Fluid Pressure Manual Valve Position Switch OBD-II Trouble Code If you see a TFP manual valve position switch DTC, it means that the transmission control module cannot determine the correct line pressure, which could impact the shift quality and torque converter operation.

4T65E Update 2002-2003 Changes A new PSA was added to all models for 2003. This Change meant the valve body machining, and the wiring harness/connector also changed to accommodate the new design PSA. The update was done because of contamination issues with the PSA. The vehicle software was also updated eliminating the PSA DTC P1810.

On 1995-2002 model vehicles, the Powertrain Control Module (PCM) may set a DTC P1810 while on 2003 model vehicles, the PCM may set a DTC P1815. Cause. The cause may be the transmission fluid pressure (TFP) switch (also known as the pressure switch manifold (PSM)). It will be referred to as the TFP switch in this bulletin.

Oct 26, 2010 · Well, I did some looking at the diagnostics for p1810. When the pcm gets this code it defaults to MAX line pressure. So that would explain the harsh shifts bcuz I can clear the code every couple blocks and it shifts fine. Now, last year I unchecked the box for p1810 via hpt, but all that does is shut the mil off.

1991 to 2013 newer General Motors vehicles equipped with 4L80E and 4L85E automatic transmissions often wear out the torque converter clutch (TCC) regulator valve bore in the valve body.
Tekton wrenchThe AFL valve allows pressure to various clutches in the transmission. When the valve bore wears, it causes pressure loss which causes various shift concerns.

See 2000 Chevrolet Cavalier technical service bulletins (TSBs) at TrueDelta, organized by model year and problem area P1810 Symptoms. Whenever the P1810 trouble code has been thrown, the transmissions line pressure is at it’s maximum. That means that all shifts are going to feel incredibly harsh. While it’s not the worst thing in the world for the transmission to run at max line pressure, it still causes it to wear and tear faster than under normal conditions.
