Review on Lisle 17232 Right Angle Funnel: Efficiently Direct and Channel Liquids with Precision by Justin Bowen

The current generation Ford 6F35 does not have a dipstick. I use this funnel to fill the gearbox through the vent cap. Access to the ventilation cover is difficult on some models. The offset angle allows me to go around and under the radiator hose. Ford claims the transmission fills for life. Most technicians will agree to a service every 30,000 miles. Some would say 25,000 miles. Some even recommend annual maintenance. I've even heard that every oil change involves draining and refilling. Importantly, this funnel makes this job easier. Look for a vent cover. It is located under the air filter box and pipes.
