I have OBD II code P1815 which is Transmission Fluid Pressure Manual Valve Position Switch.

How do you replace such swith? Do you take off the Tranny fluid pannel or is it more complicated?
Do you
have the same problem?

I seem to have this same problem with my 2003 Chevy Malibu which I just bought. Advance Auto helped me with obtaining the OBDII Code P1815. I'm also needing to know how to change this Switch? Anyone have any ideas?

Also there is a service bulletin #1477 about FALSE code p1815. So like I said, keep driving it if everything seems ok?
