Engine Surge When Slowing

[solarjustin]

I have an 04 1500 2WD with the 4.8L and I have noticed as I am slowing down from about 25mph to about 10mph the engine will surge a few times (2-3 times) as I slow. The surge is of only about 200rpm, but it is enough I can hear it as well as see it on the tack and it does it 3 times like I am downshifting through the gears. Is this normal for these trucks? I can't remember for the life of me if the truck has always done this or if I am just now noticing because I have been driving the wife’s car a lot lately. It was doing this both before and after I had the filter and fluid flush done last week so I don’t think that service affected anything.

 

Is this normal or any ideas what the solution is?

 

Thanks

Sounds pretty normal. I would guess it's a combination of the truck downshifting to keep you in the proper gear, as well as the TC unlocking and locking. All of my vehicles do this.

I would say yes it's normal, I've noticed this before sometimes more then not with my truck as well.

Good, Thanks. I have been driving my wife's V-6 RAV4 so much that when I went back to driving the truck the other week it was just weird that it did that while slowing down. I didn't think I remember it doing that much before, so it is good to here other people say they notice it happening more/less sometimes.
