Update
No further updates.I want to clarify my prior description of the problem with the LCT 1000 Allison. The fluid is coming from the rear of the transmission near or about the adapter housing (which has been replaced). The vent tube is always dry. The leak occurs after a long drive usually exceeding an hour and sixty miles.
Appreciate any help.
