LINE PRESSURE DIAGNOSTIC CHART

Test Results	Possible Source
High line pressure at idle all ranges	Wiring harness (external or internal) PC A solenoid Main regulator valve in pump stuck
Low line pressure at idle all ranges	PC A solenoid concerns Low fluid level Blown out solenoid gasket filter Line pressure blow off valve stuck open (on solenoid body assembly) Cross leaks due to loose bolts on the solenoid body Line pressure air bleed check valve in pump stuck open Restricted or damage sump filter Sticking pump regulator valve
Low coast clutch pressure	Wiring harness (external or internal) SSPC-A solenoid Coast clutch assembly
Low overdrive clutch pressure	Wiring harness (external or internal) SSPC-B solenoid Overdrive clutch assembly
Low intermediate clutch pressure	Wiring harness (external or internal) SSPC-C solenoid Intermediate clutch assembly
Low direct clutch pressure	Wiring harness (external or internal) SSPC-D solenoid Direct clutch assembly
Low low/reverse clutch pressure	Wiring harness (external or internal) SSPC-E solenoid Low/reverse clutch assembly
