During the the first to second shift my TPS % drops down to like 65% without me letting off the gas, TCS is off and it still does it. After a few rpms the tps goes back to 100 percent. Its very strange can anyone help? And it only does it 1st to 2nd.

 

TTT. No one has heard of this before?

 

well mine is an automatic, and what should the shift delay be changed too?

 

Hmmmm, my car bogs during the 1-2nd shift as well. If feels like the clutch is slipping (it's not) then kicks in.

I wonder if it has anything to do with the shift delay?
