I have searched the net for answers and found this site that proves to be pretty helpful. I have a 1999 Ram 2500 4X4 with the 46RH a518 trany. It seems to be dead. I can not find any identifying markings to ensure that this is the transmission. It does not engage in any gear but I do not know if is is electronic or hydraulic or if it is a linkage issue. Any ideas for some troubleshooting before I have to drop the transmission. I have read several posts that give alot of insight.

Thanks,
Anthony
