My problem is that it wil shift to 4hi but not 4lo, i have changed the buttons but no differanse. I think maybe it is the " Tccm"?

Hi Yes i did, I recently found out what it was. I have an kojo tune( 6.5td with ATT turbo and kojo tune), when I switched to the orginal ecm the 4wd low are working Great.
My conclusion is that there was an incorrect setting on my kojo tune, i think the tune was programmed to the trans without the auto wd type. So maybe your problem also i related to the ecm?. I did also change the 4wd switchpanel before I changed ecm but Without any diffrence.

Hope this can help you.
