Shifting Back and Forth

I run a DP Tuner and a few weeks before leaving home I was running in Stock Mode and getting on the freeway and the trans would shift back and forth between what seemed like 3rd and 4th and not want to lock in until I let off the power. This only happens in Stock Mode. I am on the road now and towinng in 40 or 60hp tow mode or if I run in 60HP econo mode no problem. Just comeing back from town in stock mode started doing the shifting back and forth again as I was getting up to speed. I Have read that a defective TPS sensor? Any thoughts?

If it doesn't do it in all tunes, I would think it's a tune problem in stock tune. Give him a call.

I agree. If it does it in one tune and not another, how could it possibly be any of the sensors?
