Australian Car Repair Issues? Ask an Auto Mechanic for Answers ASAP
Cruze is known for transmission issues.
But the trans won't shift well if the engine has a problem, like misfiring etc.
The engine light on will store a code (DTC) in the ECM and maybe TCM.
If you can get a scan tool on the car and tell me the code set, I'll tell you the next step.
If you feel it drives ok, take it to your local Holden dealer.
If it feels abnormal in any way, get a mobile mechanic to scan the car, and give me any more info as you get it.
Generally DPF codes are set when there is a boost pressure leak within the intake system.
Could be a leak in a hose connection or a solenoid.
Can you give me the code please?
