What part did you change for "P1810"? It would be a bad idea to just obtain a transmission fluid pressure manual valve position switch and replace it just because a trouble code related to that system has been set. There is a long diagnostic routine to be performed to find out what is wrong with your vehicle pertaining to that trouble code. Testing following the troubleshooting routine using proper test equipment is needed.
