Line Pressure Test

Line Pressure Test

Special Tool(s)






Component Test










1. NOTICE: Carry out the Line Pressure Test prior to carrying out the Stall Speed Test. If the line pressure is low at stall, do not carry out the Stall Speed Test or further transaxle damage will occur. Do not maintain WOT (Wide Open Throttle) in any transaxle range for more than 5 seconds.

NOTICE: Do not mistake the transmission fluid drain plug for the line pressure tap plug or the transmission fluid will have to be refilled.

The line pressure test verifies that the line pressure is within specification.

1. Connect the Transmission Fluid Pressure Gauge to the line pressure tap.
2. Start the engine and check the line pressure. Determine if the line pressure is within specification by using the following chart.

NOTE: All pressures are approximate.

2. If the line pressure is not within specification, REFER to Diagnostic Routine F: P0748, P0960, P0962, P0963 Diagnostic Routine F to diagnose the LPC (Line Pressure Control) operation. If LPC (Line Pressure Control) operation is Ok, see the Line Pressure Diagnosis Chart for line pressure concern causes.
