AUTOMATIC TRANSMISSION 5A-79
ADJUSTMENTS
HYDRAULIC SYSTEM
The procedures detailed below should be followed in the event that the self test procedure detailed in section 6, or a
defect symptom, indicates that there is a fault in the hydraulic system.
When making adjustments to the transmission, select the appropriate procedures from the following preliminary
checks.
l
Conduct a transmission fluid test procedure, refer to section 7.2.
l
Check the manual linkage adjustment (refer to the vehicle workshop manual).
l
Check engine idle speed (refer to Section 7.3).
l
Conduct a stall test (it is outside the scope of this publication to detail this procedure)
l
conduct a road test (it is outside the scope of this publication to detail this procedure).
TRANSMISSION FLUID TEST PROCEDURE
Checking Transmission Fluid Level
This procedure is to be used when checking a concern with the fluid level in a vehicle. A low fluid level will result in
gearshift loss or delay if driven when the vehicle is cold.
The vehicle is first checked for transmission diagnostic messages (refer to section 6). If the vehicle has a speedo fault
it is possible for the oil level to be low.
The vehicle is to be test driven to determine if there is an abnormal delay when selecting drive or reverse, or loss of
drive. One symptom of low oil level is a momentary loss of drive when driving the vehicle around a comer. Also when
the transmission fluid level is low, a loss of drive may occur when the transmission oil temperature is low.
If there is no loss of drive when the vehicle is driven warm and a speedo fault is registered, then fluid should be added
to the transmission.
Checking, Adding Fluid and Filling
When adding or changing transmission oil use only Castrol TQ 95 automatic transmission fluid (ATF) or other approved
fluids. The use of incorrect oil will cause the performance and durability of the transmission to be severely degraded.
Do not underfill the transmission. Incorrect tilling may cause damage to the transmission. The fluid level setting
procedure is detailed below.
Notice
When a transmission is at operating temperature hot transmission fluid may come out of the case if the fill plug is
removed. 9 the transmission is at operating temperature allow two hours for cooling prior to removing the plug.
1. If the vehicle is at operating temperature allow the vehicle to cool down for two, but no greater than four hours
before adding transmission fluid (this will allow the transmission to be within the correct temperature
range).
While hot the ATF level is higher and removing the plug may result in oil being expelled from the filler hole. This
will result in the level being low.
2. The transmission selector is to be in Park.
Switch the engine off.
3. Raise the vehicle on a hoist (or leave over a service pit).
4. Clean all dirt from around the service fill plug prior to removing the plug. Remove the oil service fill plug.
Clean the fill plug and check that there is no damage to the ‘O’ ring.
Install the filler pump into the filler hole.
5. Lower the vehicle with the filler pump still connected and partially fill the transmission.
Start the vehicle in Park with the Parking brake and foot brake applied with the engine idling, cycle the transmission
gear selector through all positions, adding ATF until gear application is felt.
