Just how does a stall converter work...and how will affect every day driving? I've got a 700R4 that likes to drop into overdrive when I'm cruising around town at 45mph which means I'm running like, 1500rpm maybe. If I install say, a 2500 stall converter, what exactly will that do to my dailiy driving? Also, what if any extra modifications/extra parts should I get if I buy one? The reason I ask is the Cam I'm installing recommends having a 2500 stall converter and while I've had several of the motor heads around my work try and explain it to me, I just can't seem to get it right in my head.
