Need Help!!! My TH350 hasn’t been ran in a long while. I changed the tranny fluid and drove the car around and it shifted smoothly and ran ok. Upon returning home, the fuild was coming out the filler tube at the tranny case. I’m thinking one of two things. The O ring is bad on the tube or the air vent hole is stopped up. I can change the O ring, though not very easy. How is the best way to check to make sure the air vent is open and not stopped up. How is the best way to unstop the air vent, with the tranny in the car, if at all possible, don’t want to drop the tranny, need a trick for this one…Any other ideas are welcome.. thanks
