car has about 193,000 though engine was replaced with one imported from japan that supposedly had about 60k miles.

5 speed transmission. When the mechanic installed the above engine (about 4 years ago at 167k miles) he drained the tranny fluid and forgot to refill it. Thus, had to replace it from the same source from which the engine was acquired. Therefore, don't know how much wear it has. Both engine and transmission have performed well in recent years.

in addition to plugs (they appeared to have some oil on them), fuel filter (was needed; cured rough idle), and several distributors mentioned earlier the Check Engine light signaled that the oxygen sensor needed to be replaced about 45 days ago. I replaced it.
