Default P1810 Trans Press. Switch Malfunction

I pulled this code off of my 2003 Tahoe. Can anyone explain what this means? How to go about fixing it?

Could it be related to this problem I am still having?
Truck randomly dies!

Thanks,

Could be loose connection or faulty pressure switch (if that's the ONLY code actively reported).

Drain fluid / drop pan
Check connection on switch
Unplug & reseat connector
Reinstall pan
Add required amount of fluid (non-synthetic)
Clear code
Start vehicle & see if code reappears.

If code reappears, possible bad switch. Same procedure, but just replace switch (5 bolts securing in place).

*edit*

may/may not be worth it to replace switch since you'll already have the pan dropped. check on pricing.

I changed the fluid and filter before I saw your post. The code is gone for now.

found this today...not sure what tranny you have:

Condition/Concern:
A 4L80E may intermittently set DTC P1810 and exhibit harsh shifts. Freeze frame/ fail records may show the vehicle was in reverse and the P1810 set shortly after a cold start. The vehicle may also have not been started for an extended period of time.
Recommendation/Instructions:
This condition may be inadvertently induced by starting the vehicle and immediately shifting the transmission into a drive range or reverse. If the PCM does not see a PRND43 input from the transmission fluid pressure switch before the customer shifts into a drive range or reverse, the PCM will assume the TFP is malfunctioning because the PCM did receive a signal from the PRND43 switch and set the code P1810. This condition would occur more easily if the vehicle has not been started for an extended period of time because of torque converter drain back. DTC P1810 does not turn on the MIL the first failure, but does store the code and it commands maximum line pressure. The customer will probably notice only the harsh shift.
Currently, there is no fix for this condition. The dealer can advise the customer to start the vehicle and allow it to run for a few seconds before selecting reverse or selecting D4 before reverse.

Interesting... I have a 4L60e in the Tahoe. The wife probably is the culprit for throwing it in gear as she starts the truck. I haven't seen a code since the original post.
