Relatives just gave me their 2000 Acura 3.5RL. It has 158,600 miles and drives like a dream. 1) Garage kept all its life. 2) EXCLUSIVELY and completely dealership maintained. 3) GUARANTEED 99.6% highway miles. I know exactly where they drove it. The car is one rung down from being showroom. The 3.5l V6 ticks a little upon startup then quiets down. For that I want to change it over to Mobil1 0W-40 European Formula. When cold the transmission holds its 2-3 upshift a LONG time. For this I just want to start by doing a drain & fill. The manual states (to the effect) to use Acura heavy duty fluid or any Dexron III fluid. I'll go with Honda DW-1 from the dealership or Valvoline Dex/Merc (suitable for DexronIII/Mercon applications-blue jug) because I have it on hand. Opinions on ATF are requested. Any Acura owners out there? The LubeGard red goes in with any subsequent transmission service. I want to feel what clean, new fluid does. Honestly, it sounds like the front spring seats have begun to shrink as they report just a little creaking. The RR door doesn't open from the outside and the driver's door button to release the trunk lock doesn't work. I haven't gotten under it yet as I've just had surgery. ANYTHING anyone has to say about this car is "pre-appreciated". IRONY: If I wanted to sell it the price would be low due to its age and mileage. I believe it's time to say good bye to the aging 1999 Saab 9-5 SE.
