Please help w/ location of solenoids!

[jerry_rickard]

My 99 gtp just threw a code 1811 and from the research on this site I think it's the pcs solenoid. I heard the tcc solenoid is right by it in the valve body.? Does anyone please have diagrams or any helpful info on how to get to these? I work at a pretty big tire shop, would it require special tools? If someone has skimatics or diagram i'll be very thankful.

The important part is getting the transmission side cover assembly off which is a job all by itself. Once off you will see the complete valve body assembly. The TCC-PWM and PCS solenoids are located on the left hand side. The TCC-PWM is right below the PCS solenoid. If you plan on doing it DIY then good luck because you will need it.
