they will still shift in open loop, you should have had either 2 or 4 O2's, not 3. The output shaft speed is used to measure slip % between input and output so pcm knows how to regulate gov press. You can use an 8.8 pulse or get a tail shaft/od housing with speed sensor. The guy that flashed out SKiM should have turned off all O2 but one, evap system etc...I will post pic after lunch
