I'm thinking of picking up a relatives 2003 Acura 3.2TL with 164k miles.
Most maintenance has been done to it. At 50k Acura replaced the
transmission under the recall it had on those models. The previous owner
did not replace the trans fluid in quite a while (maybe 100k?) and although it's not exactly slipping...how do I know it needs to be replaced and if the transmission fluid hasn't been replaced in a longer than suggested amount of time...would you recommend replacing it with the filter or just a drain and fill or 3x3? Thanks for your help.
