trans wont shift out of 1st in a 1996 chev k2500 6.5 diesel. im thinking its a sensor but wanted to see if anyone has ran across this problem before and if they knew which sensor so i wasnt just throwing money(that i dont hve right know) at it

A 1996 GM truck would not have a kick down cable or a TV cable.. It would be an electronic controlled transmission.

Perhaps the year 1996 posted is a typo?

ok so my brothers 98 chev k2500 6.5 diesel is haven shifting problems out of 1st gear. i hooked up obdII scanner and got p0758 ( 2-3 shift solenoid) and p1860 (torque converter clutch pulse width modulation solenoind valve) so i replaced both solenoids. now p1860 is still comen up so i was going to go after the wire harness. front drive shaft was in the way so i went to pull it out and wouldnt budge. i mean IT WONT BUDGE AT ALL!!!! ive been under it for 2/3 hours tryin to get it to just move. the slip yoke seems to be siezed up/rusted solid and i cant even get it to take any greese. so my question is how do i get the DS to collape at the slip yoke? ive pryed on it so hard i can see the tranfer case move. i dont want to heat it up and take a chance of warping the DS itself. ok my wrench turnin brothers help me out

speedometer is sparatic...i have found a common wire between intsr clus and torq conv clut pulse width modulator solenoid valve but to be able to get to the 20 pin connector on trans i have to remove drive shaft and slip yoke is froze up so i cant get it out of there. at this point i dont even care about the DS its dead to me. lol

odds are, its not in the wiring, but actually in the vehicle speed sensor located in the transfer case. in the last year, i have installed 4 speed sensors on chevy trucks that had the same problem as your describing.
as far as the 20 pin connector, its on the other side of the trans, and also, as a preventative measure, do what you can to get the front drive shaft out and get the slip yoke freed up. if you dont, you stand a chance of having the transfer case adapter or the back of the trans case breaking.
