2005 Chevy Epica 4 cyl Two Wheel Drive Automatic
i have a cheverle Epica LS 2005 model with Automatic Transmision. Some time when starting to move the car, the gear lever shift from PARK to Reverse and Nuetral to Overdirve(D) give a Jerking/Shivering to the whole car. Then the car moves in D position and found the RPM raises steadly without inbetween lowering which should be seen during automatic gear ratio change.
This is happening twise or thrice in a day. And then the warning for abnormal gear transmision appears whenever this issue is seen. Otherwise whenever running normal it was not there
What may be the reason?
Then I changed the Gear Trnsmison Oil.
How much quantity is needed for the full replacement. But still the issue continues and the warning lights lit through out the running wether running normal or with transmission/rpm raise.
