Witch Doctor:
I apologize for jumping into the middle of this thread, but why do you need to do number 17 & 18 in those instructions? You already have the lu in reverse, then you put the shifter in forward and put the lu in reverse again. I am lost as to what is going on there.
When I have replaced water pumps in I/Os you shift the LU into forward and leave it there until you get it all back together again.

Thanks in Advance for educating this poor fool.
