I don't see any numbers that start with a "J". The only numbers on the bottle are F41392898 on the front and B41392899 on the back, probably not the numbers your looking for. On the front of the bottle it has Dexron VI, GM Approved for use where a Dexron VI product is recommended. Also suitable for Dexron II Dexron III JASCO M315(1A) Mercon SP Toyota WS Toyota T IV Applications.
