Doing some research on adapting a bypass filter and external cooler fer the CVT and I came across some pictures of the Aisin K41B transmission. Seems there are 2 plastic plugs that were installed by the factory with o-rings. One is just above the fill port (you can see it on the left side of the picture) and the other by the transmission cooler (circled in blue). It would seem that the one by the cooler would be ideal fer a dipstick since it looks like it reaches into the pan. Any thoughts?
