Hi,

The PCM/TCM relies on three pressure switches to monitor fluid pressure in the L/R, 2/4, and OD hydraulic circuits. These components are integral to the solenoid/pressure switch. The pressure switches can only be serviced by replacing the assembly. (See pic below)

Let me know what codes you have so I can better pinpoint what you are dealing with.

Take care,

Joe

Hi,

The P0700 is a generic code that simply indicates there is a code, or codes stored in the TCM. The P0870 is the one of concern and I do see why you indicated the pressure switch. However, there are several things that can be setting that code.

I attached the diagnostics for P0870 below. Take a look through them and let me know if you are comfortable performing them.

Let me know.

Joe
