2015 transmission taking 4-5 seconds to engage in reverse or drive

[Aallen]

I just purchased a 2015 Ram 1500 SLT 4x4 with a 5.7 hemi engine. It has 800 miles on it and two days ago I went to put it into drive and let off the break and nothing happened and then 5 seconds or so later it slammed into gear. This happened twice in about 15 minutes. The rest of the day it shifted fine, yesterday it shifted normal into and out of gears. Today I get in it and it shifts fine, I get out to drop my nephew off at daycare and when I get back in it does the delay again and this time when shifting into reverse and drive. I am expecting it so I keep my foot on the break as to not have it slam into gear but I can feel it take 4-5 seconds and then it still shifts pretty hard even with my foot on the break into gear. Is this a break-in thing or does my truck need to go to the shop? Has anyone else has this issue, or know of a forum already on here I can read?

Are you applying the parking brake before putting it into park? I'm not sure if this is an issue with modern automatics, but used to be you could bind the trans in park if the vehicle is on a hill and you let park take the full load.

Nah.. not an issue.

OP... wouldn't hurt to bring it in, but you could also put a few more miles on it too, just to see. These trannies seem to have a longer learning curve. Took mine almost 3000kms to learn itself out of the 2-1 downshift clunk.

Thanks.. I figured they'd probably have that fixed by now.. I once had to save a group of stranded tourists in the middle of nowhere (Panamint Springs CA) cause they put the rental car in park on a hill to get out and look around.. and couldn't get it back into gear ;-)

I have a fairly steep driveway. When I pull in, I keep my foot on the brake and then engage the parking brake. Then I switch into park. This puts the load on the parking brake rather than the transmission. I started doing this with my last truck. I noticed when I didn't set the brake, the truck would make a loud clunking sound and would roll backwards, hard. Too leave I start, push in the brake switch to reverse and release the parking brake. Seems to work well.

That would be the correct procedure in my opinion.. so never mind my theory..

Mine is also doing something weird when downshifting from 2-1. Downshift clunk sounds about right.

I have not parked on any hills so far. Just parking lots that are pretty flat.
