HELP!! TH400 tranny cooler lines...

[Schurkey]

It puked at least half a quart after I pulled into the driveway... it took it a day to a day and a half... all in one big puddle. Does that fit into the narrative above?

IF (big IF) it was blowing fluid out the vent, the trans would be covered in fluid, which would then drizzle down, drip off, and make a big mess.

Yeah, I think what I said previously is a possibility.

It seems unlikely that it would leak from the cooler lines sitting on your driveway. What's the story with the truck? Have you owned it for a long time? Have you towed the same boat with it before? If you just bought it perhaps it was overfilled? Did you check where the level of fluid was? What does the dipstick say?

Generally, where did the puddle appear? Near the engine, near the driveshaft, passenger side or driver side?

Passenger side under the tranny. Not overfilled. I've had it for over a year. I regularly check all of my fluids; it was in the safe zone between low and full.

It has a lot of fluid on it... and the puddle was big; like 15x18 inches or so.

Reach up and put a tube on the vent line. Usually it sticks out a couple of inches on the top pass side. 1/4 inch id tubing into a plastic water bottle. Wire tie as best you can and put a load and some heat in the trans.
