Are these pumps the same as other auto trans pump in that if you can pull the gears apart they are bad?

no, but they are "supposed" to go back in in the same orientation as they were found. I haven't seen it affect anything yet, but that's not to say that it can't.

Correct.
The company that makes the gears tests them for noise after every run to see which orientation is the quietest and that's how the gears are installed at the factory. The marks might be up or down or one up and another down.
I set all of mine with the marks up just because I have been doing it for over 1600 Allisons and no other reason. It doesn't matter.

^^ good piece of information right there. So no real right or wrong just whatever you prefer

 

[juddski88]

Well. The right way is the best way...if that makes sense.

The right way is to mark the gears as they are ( tooth for tooth ) and replace them that way.
