It took some time, but I have finally tracked down what I believe to be the culprit of some spots under the truck. After cleaning under the 4runner, driving it around the block and checking (to see no spots) I finally pinned my fluid leak down.
It is a transmission fluid leak, and only when the fluid gets to temp/hot will it begin to leak.
I came across a
thread where it looked like someone had a similar issue with a 4th Gen 4runner but am struggling to find much in regards to these lines on a 3rd gen.
Does anyone happen to know the OE part #'s for the trans cooler lines? I cant seem to find them searching through toyotapartsdeal and camelback and would prefer to put the OEM parts back in, but would be open to ideas if anyone has made this work with a bit of ingenuity.
