Transmission Problem? R/T Max AWD

Has anyone noticed a change in their transmission shifting after just a couple hundred miles?

I didn't notice anything out of the norm but once I hit about 400 miles I really could feel (and see on the tach) abrupt downshifts when the car is slowing down with no break / gas. Also notice on upshift as well almost like it's staying in a gear too long.

Didn't know if this is normal and either I didn't catch it originally or if it's something with the break in period?

It's almost like if you were to be using the autostick and quickly changed the gears up or down. Vs just a small almost non noticeable up/down shift of a normal tranny.

I keep my traction control turned off, otherwise coasting feels like it has drag from the brakes. My R/T doesnt seem to have the smooth coasting ability of my other dodges.
That drag is exactly what I've been feeling...didn't know how to describe it until you said it.

However since I have an AWD there is no way that I've found to disable ESC :-(

Supposedly, your car's brain learns your driving habits and adjusts shifting accordingly every few hundred miles. So that's the adaptive learning you're feeling when the car is shifting. If you want it to shift like your pants are on fire, reset the PCM and you'll notice a difference. To reset the learning curve do the following:

Push button to run but don't start the car
Depress the gas pedal slowly all the way down
Release the pedal slowly all the way back up
Push button all the way to off
Start the car and take it for a spin, you'll notice a difference for sure

Another way to do it is to disconnect battery for 20-30 minutes.

As for the coasting issue; that's just the way these HEMIs are. Insane engine braking that I suspect is due to all that back pressure. I love it though, when coasting in first gear from 2K rpm to idle, the car burbles and pops :D
