Wrong part in database may have nothing wrong with 1A Auto order
From checking the database from 1 A Auto my Mercedes 1995 S320 saying this is for its transmission 722.6X which shoul dbe it BUT the transmission in the car is a 722.5X for some reasons. From Internet reseach to Youtube indicating 722.6X would be the transmission. Mercedes VIN number otherwise to be a 722.5X transmission and also mechanic checked after raised the car seeing it is 722.5X so I got a wrong part. I am return it so please have RMA number for me; sorry but I have always been 1A Auto customer and always be.
