ASSEMBLY
Assemble each component by reversing disassembly procedure
and noting the following points.
•Coil outer diameter and free length of each valve spring
should be as listed below. Be sure to use each one of correct
size.
Coil outer diameter and free length of each valve spring :
•Install primary regulator valve sleeve so that its tip is posi-
tioned as it was before disassembly.
•Use new TCC (lock-up) control valve gasket, solenoid gas-
ket and lower valve body plate gasket.
•Tighten shift solenoid valve bolt to specified torque.
