I have a ’05 XL 4.2 with an AOD and AC. Under a slight load it will just barley start to ping. Just slightly. Sounds like crap and is embarrassing to drive! I want to take it in but there are no service loaners where I am at and I don’t have another vehicle. So I thought I would check to see if it’s just my truck or all 4.2’s and I tested the same ’05 XL at my local dealer. Same thing as mine!!!

Is this happening to anyone else???

Oh... Tried all grades of gas, same-same.

 

what kind of tranny? it could be as simple as a reflash of the computer or something else.

 

Its an AOD. I called the dealler and they are saying bring it in. But its only 5 months old! Poor thing! hehe

 

AOD? huh. it can't be a AOD.

 

4X2 RegCab XL is available with a 4.2 V6 with 4-speed Automatic Overdrive. Has it pinged since day one? I bet a reflash would help it, that seems to be the cure-all for most of these things. Good luck!

 

i thought he was talking about the real AOD trans which has not been made in a long time. so it is probably a 4r70w or 4r100.

 

when he says AOD he probably just means a automatic overdrive transmission. so in a sense I guess you could say that we all have a aod

 

Yeah I don't know the trany model. hehe Says its an OD transmission so thats what I call it.

It didn't seem to ping when I got it. Now when I say its pinging its just barly starting to ping. Like a 1/4 ping. Just anough to anoy me.

Its going in next week.
