Yesterday we switched to a different dipstick tube for our newly installed TH350. It was a huge pain. But the old one was leaking badly where it slipped into the tranny. We ordered this TCI "Trick stick"because of it's reputation for not leaking. And it does not leak now it's a huge relief. But the installation was difficult due to just the slightest difference in bends from the original. We massaged the heck out of it and then I see that the tab used to grab a bellhousing bolt is nowhere near anything bolt-able.
So I'm going to try again but at least the leak has stopped. The next one will definitely have the seal that looks like a hat at the tranny end of the tube not the O-ring.
