Need to know what type of leak? Motor oil or Transmission oil ?
Where is it leaking from Rear main gasket, Valve cover gasket(s), cam or crak shaft seal,oil pan gasket. etc The I'll give you a price

Trans could be an AW4 or a chrysler unit. AW4 pan is longer than it is wide chrysler one is nearly square with a corner cut off. Ones with a v8 usually have the chrysler trans.

pull plug drain oil take bolts off around pan and drop then clean old gasket off and replace gasket then pan tightening bolts in a random order do not over tighten

jeeps are good for having skid plates to protect the under belly of the engine removing it should let you see the oil pan

THE MOST COMMON LEAKS ARE THE TRANS FLUID PAN GASKET, THE NEXT IS THE TORQUE CONVERTER FRONT SHAFT SEAL.

I hope they didnt over fill it when they did the seal a few months ago..

Did the mech say what would cause the overflow ??

Maybe call a trani shop & get a 2nd opinion..
Ask them what causes a overflow..
