checked the fluid level seems to be overfilled , wonder if that could be a problem?
Make sure you check the fluid level correctly:
TRANSMISSION FLUID CHECKING PROCEDURE
1. Start engine and drive vehicle for a distance of 24 km, or until transmission normal operating temperature is reached.
NOTE:
As temperature greatly affects transmission fluid levels, this operation must only be carried out with the transmission at normal operating temperature (82 - 94° C). If the vehicle is not at normal operating temperature, and the proper checking procedures are not followed, the result could be a false reading of the fluid level on the dipstick.
2. Park vehicle on level ground.
3. Move gear selector to 'PARK' position.
4. Apply park brake.
5. Let engine idle for 3 minutes with accessories turned off.
6. Lift the locking lever on the red coloured dipstick, remove dipstick and check fluid colour, condition and level.
7. If the fluid level is low, add only enough Dexron® III to bring the level into the “HOT” area.
* Inaccurate fluid level readings will result if checked immediately after the vehicle has been operated under any or all of the following conditions:
a. In high ambient temperatures above 32° C.
b. At sustained high speeds.
c. In heavy city traffic during hot weather.
d. Towing.
e. In commercial use (e.g. taxi).
* If the vehicle has been operated under these conditions, switch the engine off and allow the vehicle to 'cool' for approximately thirty minutes. After the cool-down period, re-start the vehicle and continue from step 2, above.
