  1. Ensure Bench/Drive switch is in DRIVE MODE. Rotate gear select switch to "1" position. Move gearshift lever from "P" to "R" position. Reverse should engage. Depress EPC switch. Line pressure should drop to idle pressure. If EPC solenoid functions correctly, go to next step. If EPC solenoid does not function correctly, perform TEST E: ELECTRONIC PRESSURE CONTROL SOLENOID  under DIAGNOSTIC TESTS or see LINE PRESSURE TEST RESULTS  under PERFORMANCE TESTS.
  2. While depressing EPC switch, move gearshift lever from "P" to "D" position. Vehicle should shift into drive with smooth engagement. Release EPC switch. Line pressure should rise to maximum pressure. Repeat previous procedure. Vehicle shift engagement should be firm with EPC switch released. If EPC solenoid functions correctly, see appropriate SYMPTOM DIAGNOSIS under TROUBLE SHOOTING  for engagement concerns. If EPC solenoid does not function correctly, perform TEST E: ELECTRONIC PRESSURE CONTROL SOLENOID  under DIAGNOSTIC TESTS or see LINE PRESSURE TEST RESULTS  under PERFORMANCE TESTS.
