Re: TRUCK KEEPS DYING EVERY OTHER WEEK
 
Does it ever dip below when crusing on highway, on long trips, or always stay at 14 volts? When i start truck up it goes past 14 for a couple minutes than stays at 14 for a few then settles down around 12-13 volts. Dont know if that is normal or not.

Mine drops back down to 12 or so after a few minutes...it doesn't bounce around at all, moves pretty slow.

That?s interesting. I had to drive an hour and half last night and both ways the needle stayed at or above 14. This past week during drives on the highway ranging from 30-40mins it was at 12 and this morning it started at 14 then migrated south to 12-13 and stayed there.

Don?t get me wrong, as long as this thing starts i dont give a **** if stays at 9 or 16 but i was just curious as to what others volt gauge does incase it acts up again and they have no clue of what it is.

If it ever gets to 9 i believe the engine will start to stumble and want to shut down. Had this happen when my alt went bad and was trying to get home with just battery juice( at night) :D

HummeRich23,
That condition is normal. The new engines have a system that shuts down the alternator to give more power to the motor, when everything has a full charge. If you have a dealer brochure on the 08' models, it talks about it under the engine specs....I forgot what they call it, but mine does the same exact thing......If you would like me to look it up, I will.....

I have a question for you....seeing that you have my twin....
About a week ago, I noticed that when I take my foot off the gas, or lightly apply the gas I get a slap/clunk in the driveline. Not sure what it is or what is causing it, but was just curious if you have had this issue? I only have about 6800 miles on her now.

Yeah I have the same exact trait in mine. Has done it since day one and still does It 17500 miles later. I think it is the front diff and am not sure why. My H3 does the same thing but when I had driven other h3 as rentals they did not do it. I hope others do this, it will make me feel better. I would just like to know if it the tranny or front diff?

Sounds can be deceiving but I'm 75% sure it's coming from the area of the transmission. My '08 does the same thing if you let your foot off the gas abruptly. It doesn't do it all the time though and I think it's something with the 6 speed.

Now with mine, it's not as much as a noise that you hear, but rather a nasty clunk that makes the truck shake. It does it when slowing down slowly, foot on the brake (city traffic-stop and go), and it seems as though the torque convertor sticks between 2nd and 1st gear.....as if it hesitates before it shifts down to 1st gear. Does not do this when slowing down fast. Doesn't do it all the time, so it's hard to bring it in to have it checked out.
Wondering if a programmer would remove the TCM system that causes the problem....perhaps? Any other thoughts???
