I have an 01 duramax allison lately on down shift it slams into neutral. Only when trans temp is around 190. I did the transfer case wear bracket and the rear output sleeve so i thought it was the speed sensor in transfer case. Any ideas is there another speed sensor in transmission or what else could it be?
