I have Chevrolet Cruze 2014 hatchback Eco, automatic.
I've noticed the following issue: In each ignition, the first time the transmission transmits into 3rd gear it makes a subtle grinding noise which can be felt in the gas paddle. [nothing too loud]
This phenomena will not repeat itself (when entering 3rd gear) again unless the engine has been shut down. It won't happen either if (in the first time since the engine was off) I've entered 3rd gear manually (and than later in D mode it won't happen again either).
The mechanic was clueless and was unable to explain what might be the problem. They've updated the computer software version but it did not help.
any leads will be highly appreciated! Thanks!!
