What do I look for P1810
What do I look for P1810 91 corvette LS swapped running a 4l60E and a 99 PCM.
I have a CK eng light code P1810 and my car will surge above 73MPH. It feels like its going in and out of TC lockup. I cleared the code and it comed back. I also replaced the brake switch just in case.

This code indicates a malfunction of the "pressure manifold switch" which is an inexpensive and easily replaced part that is bolted to the valve body.
It is the only way the PCM knows what position the shifter is in.
Should be less than $100 for parts and labor at a trans shop, although you may want to replace the fluid/filter at the same time.
There might be a slight chance that a misadjusted shifter cable could give this code too.
It is actually good that you got a code; often a bad pressure manifold switch will give all kinds of strange symptoms because the PCM doesn't know what position the shifter is in.

Thank you for the info, I had not thought about this possibility. It started after I shifted down into Low manually. I wonder if the shifter moved and is now in need of adjustment.

I see them online for $26. It is very easy to replace once you have the pan off and filter pulled out. One electrical connector and 5 10mm bolts. The bolts should be tightened to about 95 in/lbs which is 8 ft/lbs.
No guarantees of course, but that is my best shot and I know they do go bad.
