2005 grand cherokee trans question

fluid was black 140k on trans, no issues with the function but found very small needle bearings in the pan. Trying to find out where they came from. they are about an 1/8th inch long and looks to be 2 pieces of a carrier of some sort too. any help would be great daughters ride so she has to foot the bill for repair
Thanks

which engine and trans combo do you have? either way the trans should come apart before any more damage occurs

3.7 and 545RFE hoping there might be something that's not "internal"
being as the bearings are so small. Just grasping for hope LOL

that small sounds like planetary bearings open it up now or it WILL get worst

A 3.7 would be a NAG trans, all kinds of bearings in those .

Thanks for the info about the Nag, Yes its going to come apart
