Tools Required: Check
WARNING: This page is about a different car, the 2008 Suzuki Swift +, 2008 Pontiac Wave, and 2008 Chevrolet Aveo. However, it is still accessible from the selected car via links, so may be relevant.
The hydraulic test can inspect the working condition inside the automatic transmission (A/T) by measuring line pressure in drive (D)/reverse (R) range and idle/stall condition.
- Wedge the 4 wheels and apply the parking brake fully. Lock the vehicle in place.
- Install the J 21867 and J-21867-50 to test the hole (1) for line pressure. See Special Tools .
- Fully press on the brake pedal with left foot, shift into drive (D) and reverse (R) range and measure the line pressure idle/stall condition.
Specifications:
- The engine idle line pressure in drive (D) is 0.14-0.37 mPa (20.30-53.70 psi).
- The engine idle line pressure in reverse (R) is 0.59-0.68 mPa (85.60-98.62 psi).
- The engine stall line pressure in drive (D) is 1.10-1.23 mPa (159.54-178.40 psi).
- The engine stall line pressure in reverse (R) is 1.58-1.83 mPa (229.16-265.41 psi).
IMPORTANT:
Do not continuously run longer than 5 seconds. Extreme increasing of oil temperature may occur.
Make sure to keep interval for more than 1 minute between stall tests.
Make sure to check that there is no oil leak after installing the J 21867 and J-21867-50 . See Special Tools .
