NOTE: Remove the valves by tapping the valve body on the palm of the hand to slide the valves out of the bores or by threading a 4-mm bolt into the valves and pulling them out. It may be necessary to remove the valves and springs using a pick. If it is necessary to use a pick, use extreme caution to prevent damaging the valves or valve bores. If necessary, disassemble parts of the main control valve body in small groups. Take special care when handling the main control components, since they are the most precise and delicate parts of the transmission. Neatly arrange the parts as they are removed to avoid mixing similar pieces.

NOTE: Do not stone or polish any valves or damage to the valves can occur. If the valves do not move freely, install a new assembly.

NOTE: The bypass valve is held in with a spring-loaded retainer. Be careful not to lose the retainer when removing it.

Compress the valve springs with a screwdriver and remove the retainers with a magnet. Use a pick to remove the bypass valve retainer. Remove the individual valves and springs from the main control valve body by tapping the valve body on the palm of the hand to slide the valves out of the bores. If needed, use a 4-mm bolt to thread into the valves to remove the valves. See Figure, the Valve Body illustration for valve and spring locations. Clean valves, springs and main control valve body.

NOTE: Do not stone or polish any valves or damage to the valves can occur. If the valves do not move freely during assembly, install a new valve body.

NOTE: Be careful not to bend or twist the solenoid body leadframe or the solenoid terminals when removing the leadframe or damage can occur to the leadframe or the solenoids.

Fig 15: Removing Leadframe From Solenoids

Remove the 5 screws and carefully remove the leadframe from the solenoids by lifting it straight up evenly.

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

Using a paint marker, number the solenoids and the solenoid body to correspond with the ports from which the solenoids are located in the solenoid body.
Remove the solenoid retaining pins.

NOTE: Be careful not to wash the numbers from the solenoids or the solenoid body. Failure to install the solenoids in the ports they were originally in can result in damage to the transmission or a harsh shift.

NOTE: Do not stone or polish any valves or damage to the valves can occur. If the valves do not move freely during assembly, install a new solenoid body.

Fig 19: Inspecting Solenoid Screens For Debris

Clean and inspect the solenoid body, solenoids and valve assemblies for damage. Inspect the solenoid screens for debris that may restrict fluid flow through the screen.

NOTE: 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.

Fig 20: Identifying Positions Of Solenoid Body Ports

If new solenoid(s) are not being installed, position the solenoids in the solenoid body ports from which their numbers correspond.

If installing a new VFS, determine the base part number of the solenoid(s). The TCC solenoid, SSA and SSC are all normally low pressure solenoids. The LPC solenoid, SSB and SSD are all normally high pressure solenoids. SSE is not a VFS; it is an ON/OFF solenoid.

Fig 21: Identifying Base Part Numbers Of Solenoid

Courtesy of FORD MOTOR CO.

Item	Part Number	Description
1	7G383	SSB (normally high)
2	7G136	SSA (normally low)
3	7G484	SSE (normally closed [OFF])
4	7G136	TCC (normally low)
5	7G136	SSC (normally low)
6	7G383	LPC (normally high)
7	7G383	SSD (normally high)

If installing new normally high pressure solenoids LPC, SSB, SSD or new normally low pressure solenoids TCC, SSA, SSC, note the color of the plastic nozzle and large o-ring of the solenoid. The color will be black with a orange o-ring or brown with a green o-ring and the solenoid can only be replaced with the same color solenoid. A solenoid with a black plastic nozzle and a orange large o-ring is a normally high pressure solenoid and a solenoid with a brown plastic nozzle and a green large o-ring is a normally low pressure solenoid. Visual check.

Determine the part number suffix by checking the solenoid service band number etched on the side of the solenoid. The band number is the last number in the group 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. Visual check.

Solenoid Band Number	Part Number Suffix
1	B
2	C
3	D
4	E
5	F
