4R100 Accumulator Filter Question

Does anyone know what would happen if the 4R100 accumulator filter (little one with spring) is installed upside down? I just got everything back together after tightening loose feed bolts and think I have the filter in backwards. Not sure if I should tear it apart before adding new fluid or if it's a non issue.
Thanks!

I've read a lot of post from Mark Kovalsky and sure he could probably help...

I don't think it will be a problem. That filter is there to catch missed machining chips that are not fully cleaned when the case is manufactured. After the first few miles it really isn't needed.

TBH, I really can't remember which way I put the filter in but went ahead and added new fluid based on your response. All is good, the forward gears are back and it's shifting great.

Thank you for the response and for all the great knowledge you share on this site.
