Doing my spring fluids change today. I hadn't put a new tranny filter on my '06 Sentra after I bought it a little over a year ago, so one's going on now. I just did a drain/fill last year. Not sure if the original owner ever serviced the transmission, as there is still an orange coating of some sort of silicon on all the pan bolts. Pretty shiny for 176,000 miles. Giving MaxLife Synthetic a try in it.
