A few possibilities remain without removing the transmission from the Jeep
Might be a small piece of the TCC "Torque Converter Clutch" spring or maybe a Pump valve spring but there were zero other incorrect parts in the pan. No way I can see for a pump valve spring to get there with out other parts being tossed in there as well. Continue working the issue.
Ordered a TransGo accumulator upgrade kit along with a upgraded "White" OEM Solenoid pack. Took the old Black Solenoid pack apart - WOW what a mess to get that thing back together correctly. Chrysler came out with an improved version in 2006.
Currently in a holding pattern waiting on parts and researching issues with my other GM-TH350, GM-4L85E and Chrysler-42RLE transmissions. Always something to keep me busy spending money on around this place.
Life is good and getting better - I enjoy this sort of stuff
