Tranny Delay

When I stop on a hill, it can be a very slight hill, the tranny seems to stick. When I release the brake the truck does not start moving. What ever is going on does cause some resistance because you have to give a lot of diesel to break it free. truck revs like you are power braking. At first I thought it only did this when cold, but have come to realize it does it all the time. I thought it could be the option that you can get that prevents the truck from drifting backwards on a steep grade but I don't have it listed on my invoice and if it worked the way my truck is driving I would not want it anyway. Any Thoughts

I know when your parked on a hill it will do this and is normal. Its a break to prevent you from rolling back. If its staying on once you start forward movement, thats a problem you may want the dealership to look at. I noticed it when I first got my truck and was pulling up out of a boat ramp, scared me at first but once I figured out what it was it was kinda nice to have... but again, it should disengage once you start moving forwards.

Guess I'll have it checked out but it's not everytime, and it's not on a hill, flat pavement, the one that really bothered me was the one where I was already rolling then it's like it had a hesitation enough to throw me foward a tad....truck only has 3400 miles on it.....

Mine does the same thing. It is the hill start assist feature. It does seems kind of weird at times.

Between that and the weird times the traction control engages the front brakes, I think there may be some parameters in the ecm that are off.

well... other than the OP, this seems to be somewhat of a trend on the '15.

It's supposed to do that.

The option you are talking about is hill-descent mode which is something different.

Read your book.

Not talking about hill descent... Yes the truck is supposed assist when taking off from a decent slope, but should not be holding on that long... If it's holding on till 3rd, something's off.

Yes ^^^^^ Yes

This sensor sense the elevation and applies the breaks as suppose to so you don't roll back once you take off. If you baby take off it will keep sensing the elevation and keep the breaks applied.
