Service List

Told my son I would work on his cobalt. this 08 4dr NY spec base model with auto trans has a secondary air problem, and the dealer said it needs front end bushings ( I assume lower rear on control arm)

it also has a tad over 100k on it. I changed air filters and plugs in the fall, and changed oil and filters.

what else is known to fail and/or need service.

Is there a good link here for DIY auto trans service?

he will need to drive this for the next few years, and it also needs tires.

he will drive it here and borrow my trailblazer while I work on it part time/weekends between weather.

Thanks for any input or suggestions.

Drop pan, change filter, reinstall pan. Put in atf a liter at a time until it comes up to the full mark, shift between rev and drive until it shifts nicely. Take it for a drive and take it through all the gears a couple times til its warm. Check fluid and top up as necessary. Use only Dex 6 and I personally only use OEM from the dealership instead of those multi oils.

As for the bushings, do yourself a favor and order some moog p/n K200792 bushings so that you don't have to replace them every 9 months ( no seriously,I just went through this). Should change fuel filter, any aftermarket brand is good.

Other than that and maybe doing a once over of the front and rear engine/trans mounts you should be good.

Also intermediate shaft should be due if it hasn't already been changed depending on road abbresives used.
