Re: Funny issue with O2 sensor and Transmission

All I can think of is that forcing open loop operation is committing the TCU to a different shift strategy that isn't affected as much by whatever the root problem is...like an earlier downshift to first gear when decellerating, so if the tranny was hanging on the downshift to first, it'd have more time to complete the downshift before the vehicle actually stops or something...

Good question...I'll have to think more in-depth and get back to you...
