If the numbers do not match, damage to the transmission or driveability concerns can occur. The 13-digit solenoid-body strategy number displayed on the scan tool must match the solenoid-body strategy number etched on the main control. If the solenoid-body identification tag or replacement tag is missing or damaged so it is not readable or does not match the identification or strategy displayed on the scan tool, remove the transmission fluid pan and filter and locate the 13-digit solenoid-body strategy etched on the main control casting ( Figure 4).

If the solenoid-body identification and strategy displayed on the scan tool match the solenoid-body identification tag or replacement tag, then the solenoid-body identification and strategy are correct for this transmission and a solenoid-body strategy data download is not required. Compare the solenoid-body identification and strategy to the solenoid-body identification tag located on the left side of the transmission case. On the Ford 10R80 transmission models, the solenoid body/strategy identification is as follows: The 13-digit solenoid-body strategy number consists of only numbers (1).

Lower control valve-body assembly with solenoid valves.

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. This data file is programmed and stored in the vehicle’s TCM. The solenoid performance data file is stored on the Techline Information System (TIS) website. This file number is marked on the solenoid valve housing end or on the valve body itself ( Figure 3). The current versus pressure data-points results are saved and assigned a file number. The solenoid valves are tested two ways, with an increasing and then a decreasing electrical current applied to the coil winding. This information is referred to as solenoid current/ pressure data points. Each solenoid valve is tested after assembly to determine the output fluid pressure (flow rate) at certain electrical values, applied to the coil winding. The GM transmission control solenoid valves 1 through 8 ( Figure 2) are pressure-regulating valves.

The 10R80 solenoids are similar to the 6R140W solenoids referred to as solenoid body/strategy identification. This is very similar to what has been covered in the past with the 8L90 found in GM vehicles referred to as solenoid characterization. The first thing to remember when replacing the valve body and/or just the solenoids is the TCM will have to be updated. Here are overviews of the 10R80 and 10L90 transmissions ( Figure 1).
