I need help with my tranny. It is blowing trans fluid out from the bell housing area but only when towing a trailer, and no it is not overfilled in fact I have drained it down to just below the add line and it still does it. It has a tranny cooler on it but no temp guage. I have pulled over after it starts puking fluid (this is real obvious because of the smoke screen behind me) and checked the temp of the pan with an IR thermometer it reads about 220-230. I'm not sure what constitutes too hot though. As long as I'm not pulling a trailer it never leaks so I assume this is related to the head buildup. What gives? is 230 too hot or do I have a bad front seal? I don't see why a seal would only leak when hot :dunno: does the fluid thin that much as it gets hot? Oh yeah it's a '90 4.0L NP231 if that matters. Also the cooler measures 5x18 and the factory cooler in the radiator is plumbed in as well.
Thanks for any help
