What are the factory recommended intervals for a tune up/spark plug change and a transmission fluid change for a 2005 Jaguar S Type 3.0? Thanks.

 

I believe the spark plugs as per the maintenance booklet is at 100k miles.

Now, with the transmission fluid. Apparently it's "sealed for life"...but personally, I am planning to change mine soon. There are a few threads on here covering that topic. There is also a video by a fellow member giving instructions on how to do the trans fluid change as well.

 

3.0 plugs are every 70K miles (4.2 are 100K). Full service chart is on this site / in JTIS (free download).

Trans fluid change details in stickies. Make sure done right!!
