gauge question OBC question/ auto transmission

[pinnaclebass]

what is EML on gauge? or OSC or possibly DSC? on 1990 2.5 liter m20

plus Check Control pops up on OBC sometimes when turning car off.
i figure this is light control module<<seeing as how I replaced one already with one bought from a junk yard. <<new one costs $ 400. there must be someway to get a good one that does not break down!! come on!!

and randomly the car will shoot out check oil pressure sensor.
but it seldom does this. <<should this be taken seriously?

also car has auto transmission and i noticed the other day after driving to work and turning the car off, water or coolant was dripping and cooling off transmission. It was a hot day (over 95 degrees) and drive was over 85 MPH for 10 miles.<<running late
has not done so since, but what would this be attributed to. never seen this before. is it a problem? or is it just tranny cooler working... maybe foreshadowing a problem. transmission and engine are original with over 200,000 miles on it. best auto transmission ever experienced. still ticking and never misses a shift.

- was your air conditioner ON? if yes, that was just condensate dripping from it's drain ;-)

<<< if it does that again.. check oil level. This happens to me about once a month(i use my E30 to work everyday)....
