BD transmission ,TC and MAg-Hytec reg pan. Drained TC and pan, 12qts ATF+4, looks full and the first moderate left and right corners (only ones on my way home before parking it) both produced a jump in rpm as it seemed to suck air. Questions are, 1. do different torque converters have different capacitys. 2, last time I used a regular 727 filter with the open media on the bottom, this time I used a 2000 dodge ram filter with the covered bottom w/ port. 3, BD said to be low rather than high so what is it taking you guys to fill? 4, Finding atf+4 as we know is random at best except the dealer. Last time I used +3, today BD told me only +4 or +3 with friction modifier. Any ideas why? 5, where did I set my beer?
