The top is a "Measu-Funnel" and the bottom is 3/8" tygon tubing connected the the dip-stick hole for the transmission. I can't use the fill-plug since this 02' has the TSB Oil Jet for the second gear installed into the fill hole.
Why am I putting a Class I stacked plate cooler on my 02' Honda Odyssey? Because the transmissions run very hot and man feel should have a stock cooler and servicable filter installed. Yep, no serviceable filter on the van.
