Totally a hypothetical question ;)

So, all in all I hope I learned this lesson without any pain. I now understand what that kickdown really does. I always assumed it just kicked the trans into a lower gear for passing and such. I thought without it you just would be accelerating in Drive instead of 2nd. I had no idea it altered line pressure. To say I don't know much about how an automatic transmission works is an understatement, but I'm learning. Hopefully I don't get to learn how to rebuild one anytime soon...
