Trans

Took it 2 miles to miles to a buddies house shifted fine did not overheat was hanging for about an hour then to father-in-law‘s 2 more miles and got hot 240 than let it cool for an hour and drove home shortcut 1 mile that’s when it was not shifting correctly

How is it not shifting correctly? What exactly is it doing?

I've driven several loose converters on the street and never had any issues. My current converter flashes 5600 and works fine on the street.
