Greetings All! I'm a fresh recruit to the Highlander ranks, thought to check w/ the experts online. Doing the routine maintenance on a 2005 model, found a boatload of transmission filter kits (ranging from $12 - $60 online, several claim to be 'Toyota OEM'). Is there any real difference between these, any warning signs to avoid OR cues that one is the real thing? I'm in FL & have seen the fangs-out blatant predatory practices in many dealerships - but also know that true OEM is often best.. any advice to help me avoid the sharks (online and / or IRL).. Many thanks in advance, will be around to learn from others much as possible! Cheers all!
