I pulled the transmission tube from my 98 Expedition with the 4r100 Tranny.
It is a 2 part tube. The upper part is long and curvy and has an o ring seal on it.
The lower part is an offset elbow that presses into the transmission body.
There is no seal or o-ring where that lower part inserts into the transmission.
That connection is a source of a transmission leak.
What should I use to seal that connection back into the transmission body?
It looks like the last time someone serviced that part they used RTV and Teflon tape, which did not work.
