The Z28 is slowly approaching the 100,000 mile mark, and I definetly want her around for another 100,000 miles. On my list of things to do:

1. Drain and flush coolant
2. Change oil(duh)
3. Change automatic tranny fluid, not a full flush.
4. Change serpintine belt
5. Replace rear tires. Again

I seafoamed the engine, installed an oil catchcan, and changed the sparkplugs and wires about 30,000 miles ago. I used the OEM spec A/C Delco plugs again. I'm debating on doing this again. Advice would be appriciated.

Other than the smoky burnouts, my car has a pretty easy life. 90% of the miles on it are interstate going 80mph. Car runs great BTW.

Any other general maitence items you recommend???

I hope this isn't the first time you've had your tranny fluid changed. If memory serves me correct this should be done every 2 years or 24K miles whichever comes first. Other important, but often forgotten fluids are the brake and power steering especially at this point.

Another point to consider is your wheel bearings. How are they holding up? Lastly, you might want to consider a rearend different fluid change - just be sure to put in some of the genuine GM additive if you decide to do so. Just my $0.02 for now, good luck.

Coolant, tranny, and rear end oil were all changed 30k miles ago.

i thought the manual said you could change it every 50k miles as long as you don't tow with your car or use it fora taxi or something like that?
