#437, "RE: B&M TrickShift Fluid" In response to In response to 1
DO NOT USE TRICK SHIFT, USE ONLY ATF+3 or if 1999 or up use ATF+4
and joe you info is incorrect, a quicker firmer shift (harder as you call it) is BETTER for your transmission, there is much less heat generated by a quick shift as the tranny is not slipping to keep the shift longer.
Car manufacturers make the shift slower for the average driver who wants a smooth shift, but its much worse on a tranny.
The faster you/tranny can shift into each gear the better for the tranny.
