It has an auto trans in it. im gonna search for that ats fix here now, and i drove it to a shop so she was warmed up.

the batteries tested good as well as the alt, but it wasnt bench tested. its really wierd, its has a "surge" at idle, a good 2volts. had a tester on the batt w it running and it read 14.1v and the surge came and dropped it to 12.2v this happens a couple times a minute. im at a total loss here fellas!!

So, if my batteries and alt test out ok, what would be the next thing for me to look at?

Thanks, its got the FASS fuel system in it, also has the edge attitude w outlook monitor, 5" turbo back exhuast, aem air intake. im gonna take it to a shop and have the batteries load tested today, and go over all the cables/connections as well. thanks for the info!!

First id like to introduce myself, im from delaware and have a 99 3500 dually. My problem is the trans shudders alil bit around 40-50mph, i took it to the trans shop and they got 2 codes, 1693 on the engine side and 1682 on the trans side of the tester. i know the 1682 is a charging issue, coyuld this cause the trans to act up? also, when i start the truck for the first min or so, the volts read way low like at 10, then slowly rise up to above 14v, while at idle the truck will have kinda like sudden dips in the lites and the noise the fuel pump makes dip for a sec and then normal, any help would be great, looking forward to the site as well, im fairly new to the cummins. thanks!
