Yeah, they don't have a cotter pin in the doohiky and the pin slipped out, if I am correct you will need to drop the transmsion to fix this. PM h395, he has info on this. Do not force it, will just break more ****. Good news, if you drop the transmsion, makes sure you do all of the upgrades!! Many things posted on those in syn thread last 100 pages or so.

Hopefully it aint this, but it is a known weakness. I bet the guy new it would be a costly fix, why you got it cheap. Thanks to h395, guess you dont need to remove tranny.

So it doesn't go into park either? My guess is shifter linkage, maybe pin fell out when it was in R.

If this is your issue, it is this part I do believe, 3 bucks, lol. Now that is for an aspen, it may or may not be the same for a Ram, but you know what it is.
