Special Testing Procedures





The special tests are designed to aid the technician in diagnosing the hydraulic and mechanical portions of the transaxle.

Pressure Test

Pressure Tap Location









NOTICE: If the pressure is low at stall, do not continue with the test or further transaxle damage will occur. Do not maintain Wide Open Throttle (WOT) in any transaxle range for more than 5 seconds.

NOTE: In order to connect the pressure gauge to the transaxle, use an O-ring to pipe adapter (5/16-24 to 1/8 inch pipe thread adapter).

This test verifies that the pressure is within specification.

1. Connect the Transmission Fluid Pressure Gauge to the appropriate pressure tap.

2. Start the engine and check the pressures, see the pressure charts to determine if the pressures are within specification.
