Automatic transmission oil and filter change

Hi,

I want to change the Automatic transmission oil and filter in my 2.2 Vectra engine z22se, how??, where is the location of the filter??

Many many thanks😃😃😃😃

Filter is in the gearbox and requires the casing to be opened. It is not financially viable to replace the filter.
Just change the oil regularly.

Hi,

Thanks for reply but why it's not recommended to replace the oil filter.

Gearbox out job.
