first lets start off with the 4x4...my 4x4 high light flashes 10 times then off for a min or two.. if i press the 4x4 high you can hear the t-case motor switch to 4x4H and if i press 4x4L you can hear it switch to 4x4L so i know the motor is working... i looked up online and people said that the ground wire next to the case can be broken but it seems to look ok... hooked up my scanner and i get code P1824 4-wheel drive clutch relay circuit...

now to the trans.. i did a trans filter and fluid change and the fluid was really good nice and red and no bernt smell to it... so my problems i am having is, 1. i get a whine when starting up the truck. maybe air is getting in the tranny? 2. trans shifts fine and smooth but when down shifting from 2 to 1 kinda has a small kick. maybe from trans or driveshaft? maybe needs more fluid? i dont get no codes or no o/d light on....
