    My old 99 half ton(180k miles) had this issue, i never got it fixed. Also test drove a 2002 half ton(94k miles) today that had the same issue So it must be common in the older trucks.

    Never had an issue with my current 2500HD's(6.0L with 33k, dmax with 45k).

    the wires at the end of the shifter could be broke from all that shifting over the years. At least thats how i fixed my 99 1/2 ton with 180k on it

    How hard is it to pull the shifter off and replace the whole assembly

    Not hard at all but the shifter assembly's are expensive, which is likely where most of CAT420's $200 cost came from. You can repair the broken wire on the old one for an hours worth of labor.

    I tried to fix that wire on mine. Guess what? It is still broken too!!! Look around on Ebay or something first. You may luck out and find one cheaper than the dealer
