I recently purchased an A618 overdrive trans and there are no 46RH/47RH markings at all to be found? this is a 3 pin plugin so it is a L/U converter. 1993 is cast in on the tailshaft so I assume that is the year.? here is what is stamped on the drivers side pad just above the pan:
PK52118307 1732 2722
supposedly this was rebuilt but I want to know what I have as I may want to make some upgrades as this will be going behind Hemi if JW ever makes there ultrabells again! TIA TBF
