I have been doing things the uneducated way e.g oil changes, changing coolant, fixing sensors that run awry, and replacing things when they break. However, I'm not sure what else to do. For example, I've never changed the transmission fluid, brake fluid, etc. because I read that when your mileage is that high changing these fluids could actually do more damage than good. I'm in a really bad place because I completely love this car (looks surprisingly good cosmetically-im really into cleaning it) and I want to keep it when i get a newer one. I just feel bad because I haven't been very good to it mechanically.

Ok.......question, 1st, do you happen to know if it ever had a trans service?
Because, I did a trans service @ about 90,000 & 7,000 miles later, I have no issues......trans shifts like a dream....
My theory on the trans fluid change is..... that after many years & high mileage the trans fluid starts to break down, gunk up, turn brown & sticky.... causing the valves & checks to stick causing the trans to shift erratically......
2nd, The coolant system's on the E36 are something to keep an out for......
Upper radiator neck cracks @ about 90,000 miles....
also check to see if you have a plastic thermostat housing, if so on your next t-stat replacement......replace the plastic housing with an aluminum one!
also, how is the suspension holding up?
