Good thread - I took my trans swimming at 69k miles, and as you might imagine it was not happy. The trans shop that rebuilt it for me has turned out to be the biggest group of idiots I have ever had to work with, plus they will not install a bung in the pan, claiming it will eventually leak and the mod would void their rebuild warranty. The NAPA T-adapter is exactly what I was looking for - the one concession I got out of the trans shop was them installing a HD trans cooler, but I am having regular trouble with the trans burping up fluid when it gets hot. I need the temp guage so I can see what it is doing, the T-adapter should not give them any cause for grief. My popup is big and heavy, and still running stock 3.73 gears with my 33s does not help the trans run any cooler, especially on hilly, back roads.
