Hydraulic Pressure Tests:

Pressure testing is a very important step in the diagnostic procedure. These tests usually reveal the cause of most transaxle problems.

Before performing pressure tests, be certain that fluid level and condition, and shift cable adjustments have been checked and approved. Fluid must be at operating temperature 65-93°C (150 to 200°F).

1. Install an engine tachometer

2. Raise vehicle on hoist which allows front wheels to turn, and position tachometer so it can be read.

3. Attach 690 kPa (100 psi) gauges and special tool L-4559-2 to ports required for test being conducted. A 2068 kPa (300 psi) gauge and special tool L-4559-2 (C-3293) are required for reverse pressure test. Test port locations are shown in illustration.
