Au­to­box fluid re­place­ment

- Mark Salter Tonga · Vauxhall Astra · Vauxhall Motors · Iceland · Belgium

I want to re­new the au­to­matic trans­mis­sion fluid and fil­ter on my 2006 Vaux­hall As­tra 1.8 petrol au­to­matic es­tate with the Z18XER en­gine as it is near­ing 80,000 miles. I think I can see a drain plug, but not any way to ac­cess the fil­ter/strainer. Could you give me any guid­ance?

For some rea­son the in­for­ma­tion I have from Vaux­hall on your As­tra is slightly con­fus­ing. If it is an As­tra G then the XER en­gine is not listed, and if it is an H then the au­to­matic gear­box op­tion is not listed.

Mak­ing the as­sump­tion that you have the AF17 gear­box, the strainer is within the two sec­tions of cas­ing and can only be re­placed when the gear­box is stripped down. Although the strainer is nor­mally sold with an ac­com­pa­ny­ing gas­ket, the job is not a sim­ple one and re­place­ment is not re­quired dur­ing a nor­mal fluid change.
