My 46re in my 99 R/T keeps having a leak at the neutral safety switch. It's actually dripping now. Plus I notice the rear output seal is dripping. I know it's not the original transmission because it has the square neutral safety switch. But I'm curious as to what this transmission came out of. I was able to find out on my old 73 Charger what vehicle it's 727 came out of. I was wondering if you anyone knows about this 46RE the numbers I see are PK52119755AA, it's kinda hard to see so there maybe a number off. Then there is a space with a 1641 then another space and 1235. I see the overdrive unit has date of 2001. I just was wondering what it came out of.
