Stop in for a cup of coffee

Morning guys

Well, I'm not sure how, but apparently flushing the coolant system causes the transmission to fail???

Car won't go into gear (any gear) as if the park lever is not disengaging to allow the shifter lever to function...

:BangHead:
Seriously look at the shifter on the trans make sure it is moving when you hit the buttons.
