Spewing trans fluid occasionally?

[toddy]

Ok so I made it to phoenix but I think I barely did. Just outside of Tucumcari NM I stopped and noticed I was leaking trans fluid. I didn't thinmk much of it and continued my trip another 100 miles. When I filled up and checked my load I noticed fluid all over the back end of my truck. I looked underneath and the entire under carriage of my truck was coated in it. It was dripping from everywhere so I couldn't pinpoint where it was coming from. The tranny temps were good the entire trip and only peaked at 220 from holbrook to Flagstaff. It stayed below 160 almost the entire trip. The tranny is full according to the dipp stick and I haven't added anything to it? It only would leak every now and then Any thoughts? I didn't have any Converter slippage at all. I was only hauling about 1500 pounds in the bed. Whats everyone thoughts?

it sounds like your filter is getting clogged and building up to much pressure

Usually it spews when it is clogged, like a cooler line or something. I remember you replacing that bypass line, maybe it has something to do with that.

But it only did it on two occasions. I don't get it. Im gonna take it to have it looked at tomorrow

inline filter or filter in the tranny i have seen it many times change those and you will be fine.

[toddy]

So I just need to go ahead and do a fluid and filter change? Ill do that tomorrow

[badazzstroker]

also check inline to the cooler and see if it has a filter there some do and some dont if it does make sure to do that one also and everytime you do a tranny service.

My tranny did this some time back. It turned out to be a seal on the front of the tranny. The tranny guy said it's common on the 4R100s.

I had driven all over the place empty, I had towed a 6Klb Travel trailer - didn't do it. When I took our new (at the time) 5th wheel over to the coast above SF, it was spewing when I got there. I added tranny fluid while there. I drove around all over the coast for three days (not towing) didn't do it. On the way home (5er attached) it did it again.

The shop replaced the seal - hasn't leaked a drop since. I've pulled my 5er (12K) all over since, hauled loads in the bed and DD. Nothing, dry as a bone.

It's usually the front pump/converter seal getting hot and leaking, I've put several in and the aftermarket seals seem to not have that problem, can't remember the brand.
