Decent amount of "slop" in my '09's tranny.... Anyone else?

I would say shift it into reverse and wait a few more seconds before moving your foot off the brake onto the gas. If that makes things better then the pumps might not engage when in P, which may be by design and not a fault. I'm not familiar enough with these transmissions yet to know if they should or shouldn't.

And you can always two foot it. Put left foot on brake and give it gas until you feel it starting to move then let off the brake and you shouldn't roll forward at all.

How steep of an incline are we talking about anyway?

Not steep, Jay. Not steep. Not sure of the exact angle, but it's not that steep.

And yeah, that's good advice about simply waiting first. That's what I need to do. But, I don't think I should "have" to wait. That's a work-around to what I believe is a problem.

I appreciate the input on this.

Roger -- Yep, I'm going to see if I can get this looked at. It just doesn't feel right to me. The whole tranny has never felt right to me since day one, but I just chalked it up to the new body style's different characteristics. I think there might be a little more to it, though...

There very well could be an issue especially if it's not a steep incline.

Also you could try this. When you get to work in the morning pull into your spot and then put it in reverse. Same issue? Or does it work as expected.

Snow -- You mean to see if it's something that happens only right after sitting for a while? That's a good idea. I'll give that a whirl. Thanks!

 

[snowjay]

Yes, exactly.

I was able to test this today in my Tahoe. I was parked on a slight incline facing down. Not very steep but enough so it rolled forward a bit when I put it in P. I shut the truck off, went into the store and came out about 15 minutes later.

I got in, started the truck, put my glasses on, seatbelt, stepped on the brake, put it in R, let off the brake and the truck didn't move, in fact the 5.3 rolled it back slightly and held on the little incline. I stepped on the gas and back I went on my merry way.

Now maybe if I was in the store longer and it had time to cool down and completely drain it would of been different but that's a point of reference for you.

Hmmm... Thanks for testing yours out. I'm going to keep an eye on mine, and see exactly how often it happens, and under what circumstances.

Thanks again.

No problem. I knew it wouldn't do it when I've been driving around and shift from D to R and go backwards. I do that every day backing into my parking spot in front of my condo (street is on an incline) but I was out today shopping and one of the places had a slight incline with a fence in front of it so I thought of you and figured I'd give it a shot. Too bad I wasn't in the store longer for a better test.

I haven't checked to see how my much give there is in the driveline when its in P yet. My old car there was about 1" in either direction (I actually put a tape measure onteh ground and watched how far the edge of the bumper moved as I pushed it) but it would always return to "center." Although without the ruler for reference it seemed further.
