I noticed that mine does it with the Smarty loaded, but seems to quiet down when it isn't loaded up. Maybe it's just the nature of a Smarty? :)

I've had that problem for a while. After the transmission service it went away but came back after about 2000 miles. Currently the truck does it..and I just figured I'd correct it by giving it a little more throttle than usual. That trick didn't work. So now I'm out of my warranty and not sure if I'll try and tackle the above myself, just leave it until it's a serious problem or pay someone to do it. Knowing me I'll just forget about it again in a few days until it becomes a problem :argh: Thanks for the above info. I need to cut and paste it for future reference.:rocking:

Well there is a TSB out for it so warrenty or not they fix it for free.

As for his problem even though they have a TSB out about it being he is out of warranty they will not fix it for free. Many times they need to replace parts in the trans to fix the 1-2 shift problem, the parts are free only under warranty.

Warranty's suck! the Dealerships here in dallas suck with tranny's I had a gas truck in the shop for over a month trying to get them to warranty the tranny with only 33k miles

Y'all need to find new dealers... All the ones around here (all brands) fix stuff that has a TSB out for a PROBLEM for free as if it was under warrenty. I would call and ask.

Dealer didn't check TBS
 

Dealer said $4000 for a new transmission...told him about TBS...serviced it and change solinoid...wow what do you know...it works again...

hey that is great to hear :U::U: nothin' like helpin another diesel head out in a time of need..... and i know from experience how much of a time of need a transmission is.....

Glad to here it and...

:hi:

Stay around for a while!

I had a simular humting issue and it all but went away when i installed Suncoast VB and TC. It was allways there under light load with stock tranns. With Suncoast parts it only shows up every once and a while and when it does its hardley noticable.
