How do you know? Did you remove the line? Otherwise I don't have an answer other than to say it might be proper since the pump would be turning much slower in P or N. If you have no shifting issues it's probably fine, but others may know better.

Yes, I removed them to install an auxiliary oil cooler to identify what line was in and out and no flow, when I moved the gear selector to gear then there was flow

TP:
What engine is in your D? I seem to recall one of the older style trannys, that does not pump the fluid unless it's in gear?
My guess is that you have the 44RE which came behind the 5.2L, or the 46RE that came with the 5.9L
Transmissions are not my strong suit, so just spitballing here.

5.2L is the engine, if it was designed like that, can something be done to the Valve Body so there is always flow? Thanks..........TP

Google is your friend there. I have heard that there may be a remedy, but I've never owned a vehicle with the 44RE in it.

If it was designed like that then why do you even want to change it? The design probably means nothing bad will happen when in P or N.

44RE doesn't pump fluid through the cooler in park, but it should in neutral IIRC

It doesn't in neutral only in gear...........
Just because it was designed like that doesn't mean is effective, here in P.R. where is summer all 12 months we need to keep trannys cooled, like my 2001 cherokee sport with AW4 2wd it has flow once the engine is ON in PND3and1-2
I am fixing my 95 Grand Cherokee 42RE and If it has the no flow I will find the way to fix that, no wonder the 44RE won't last as long as the AW4 does.....maybe the manual valve from TransGo can fix that, will see...thanks for the input maybe someone already has fixed this and can share the how to........TP

one thing you should consider is checking the converter drainback valve.. not really related, but that has been the cause of many 4xRE transmission deaths.

Also make sure your bands are adjusted.

There really shouldn't be any need for cooler flow in P/N ..
