Solenoids

Solenoids

WARNING: Before beginning any service procedure, REFER to Safety Warnings . Failure to follow this instruction may result in serious personal injury.

Removal

1. Remove the solenoid body leadframe. REFER to Solenoid Body Leadframe .

2. Using a paint pen, number the solenoids and solenoid body to clearly mark which solenoid was removed from which bore in the solenoid body.





3. Remove the solenoid retaining pin(s).





4. Remove the solenoid(s) from the solenoid body.

Installation

1. Inspect the solenoid(s) for damage. Inspect the solenoid screens for debris that may restrict fluid flow through the screen.





2. NOTICE: The solenoids are calibrated from the factory and are not all the same. Failure to install the solenoids in the ports they were originally in can result in damage to the transmission or a harsh shift.

If a new solenoid is not being installed, install the solenoid(s) into the bore from which it was removed.

3. If installing a new VFS (Variable Force Solenoid), determine the base part number of the solenoid(s). The TCC (Torque Converter Clutch) solenoid, SSA (Shift Solenoid A) and SSC (Shift Solenoid C) are all normally low pressure solenoids. The LPC (Line Pressure Control) solenoid, SSB (Shift Solenoid B) and SSD (Shift Solenoid D) are all normally high pressure solenoids. The SSE (Shift Solenoid E) is not a VFS (Variable Force Solenoid), it is an ON/OFF solenoid.










4. If installing a new LPC (Line Pressure Control) solenoid, SSB (Shift Solenoid B) or SSD (Shift Solenoid D), note the color of the electrical terminal area of the solenoid. The color will be blue or green and the solenoid can only be replaced with the same color solenoid. If a new solenoid with that color is not available, install a new solenoid body.





5. Determine the part number suffix by checking the solenoid service band number etched on the side of the solenoid. The band number is the third digit on the side of the solenoid and will be a 1, 2, 3, 4 or 5. Use the following table to determine the part number suffix and match the new solenoid base part number and suffix with the old solenoid. Install the solenoid in the solenoid body.










6. Install the solenoid retaining pin(s).





7. Install the solenoid body leadframe. REFER to Solenoid Body Leadframe.
