Thumbs down Transmission Filler tube leaks

I have a 99 f250 v10 w e4od transmission with 100K miles.

Problem is filler tube leaks where it is inserted into transmission. Leaks directly on exhaust pipe. Fluid collects inside heat shield, smokes, boils etc.

I removed tube-some red stuff at lip no o-ring, bushing etc. Check with ford dealer no bushing o-ring etc shown on microfitch. I found an o-ring that fit between tube and transmission. Still leaks. After hard pull noticed a lot of smoke looked found tube leaking from up high. Seems some genius at Ford put a 2 piece filler tube on my truck. It was leaking at joint.

I removed tube, a real pain, replaced the o-ring in the joint, replaced the o-ring at joint between tube and transmission, filter etc. Again still leaking.

Anyone else had this problem? Or have any ideas on how to stop leak? I have been told not to use silicone as a joint sealer. I am ready to use epoxy putty if I thought it would work.

Transmission is a pain to fill. Oil reads high on the stick on one side. I guess it sticks to the inside of tube. After it sits a while it reads ok. When the fluid change happened the transmission was finally filled but after sitting overnight was extremely overfull when cold. After running a while it was correct.

I had the same problem with my filler tube after someone worked on my truck and banged the filler tube enough to bend it slightly. I bought some High Temp (Red) RTV made by Permatex which solved my problem. I had to drain a little of the transmission fluid out so it wouldn't leak out while the rtv was curing. With the Filler tube installed, I put a good bead of the rtv around the filler tube where it mates with the transmission. It's been about 4 years since I did this and it hasn't leaked a drop.

Hope this helps.
