In ~April of 2015, we adopted a 1999 automatic with ~112,000 miles on it. Haven't done much to it yet (floormats and wiper blades when we first got it), but now the regular maintenance is starting, so here's a record of what I've remembered to record:
August 23, 2024 144,950mi
September 2, 2022 142,856mi
Disappointingly, the misfire returned. Oil was leaking from the valve cover gasket into 3 of the spark plug holes, so cleaned the valve cover, installed a new gasket, new plugs and wires, but no joy. Went with a Delphi coil pack this time, and time will tell how much better it is than the Beck, or not.August 19, 2020 ~140,500mi
Drained & refilled ATF with Transmax V, seems like we only replaced about 2.5-3 quarts this way - of a 6 quart total capacity. Also drained & refilled differential oil - nothing terrible looking in there, just had never looked since purchase. Noted absence of shift linkage bushings, looking for replacements now.December 29, 2019 138,700mi
Applied 3M 1080 vinyl to chin spoiler area - paint was flaking on the left side at time of application, might need to remove and re-apply if delamination becomes severe.December 15, 2019 138,633mi
Oil and filter change, synthetic 10-40, again reused crush ring on the drain plug.Somewhere around 132,000mi
Replaced shock absorbers with Bilstein-S. Also swapped wheels/tires with the 1991. in response to a bad alignment problem on the left rear, severe wear on the inside inch of tread (down to metal). Aligned at Big Chief tire, plan to have alignment rechecked in January 2020. Replaced eccentric alignment washer-bolts with new, hope to keep from having another "severe alignment drift" eat a tire. Headlights replaced with LEDs.November 18, 2018 129,890mi
Oil change, Quaker State 10-40, Fram ToughGuard filter, reused the crush ring on the drain plug.November 15, 2018 129,880mi
Ignition system refresh in response to a consistent misfire on cylinder #3:November 29, 2017 124,100mi
Mostly preventative, triggered by a bad alternator - the rest I just didn't know the maintenance history - now I do, replaced all these with new:November 1, 2017 124,000mi
