I have to buy a new transmission, but need help identifying the one I need to order. I have a '98 Expy EB 4WD- the transmission case tag shows the following: 3K (in 2" high letters), then to the right, F8UP-MB (F8 represents the year 1998 - don't know what MB is), and underneath that is PRB-V1. Any ideas as to which transmission it is? E40D? 4R100? or 4R70W?[/align]
