Solenoid Characterization

WARNING: This page is about a different variant/trim than selected.

Transmission control solenoid valves 1 - 8 are pressure regulating valves. Each solenoid valve is tested after assembly to determine the output fluid pressure at certain electrical values, applied to the coil winding. This information is referred to as solenoid current/pressure data points. The solenoid valves are tested two ways, with an increasing and then a decreasing electrical current applied to the coil winding. The resultant current versus pressure data points are saved and assigned a file number. This file number is marked on the solenoid valve housing end or on the valve body itself. The solenoid performance data file is stored on the TIS web site. This data file is programmed and stored in the vehicle's TCM. Replacing any of the following components will require the TCM to be programmed with either the new or existing solenoid valve performance data, depending on what component is replaced.

Transmission assembly - program the TCM with the new data file stored on the TIS web site for all pressure regulating solenoid valves.
Lower control valve body assembly with solenoid valves - program the TCM with the new data file stored on the TIS web site for all pressure regulating solenoid valves.
Transmission Control Module - program the TCM with the existing data file stored on the TIS web site for all pressure regulating solenoid valves.
One or more solenoids - program the TCM with the new data file stored on the TIS web site for all pressure regulating solenoid valves that were replaced.
