In-Vehicle Repair: Solenoids: Installation

Inspect the solenoid(s) 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.

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.

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 solenoid, 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 an orange o-ring or brown with a green o-ring and the solenoid can only be replaced with the same color solenoid. A solenoids with a black plastic nozzle and an orange large o-ring is a normally high pressure solenoid and a solenoids 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
