WHAT modulator is in the trans..Metal OR white plastic..IS there a crush washer under the modulator? if there is a crush washer then THAT could be the problem.


Those transmission have an oil distribution tube & connector sleeve between the 2 clutch packs..if 3rd gear clutch pack doesn't fully lock-up or "burnt" previously then that oil distribution sleeve is a good possibility(slight crack).
