I've read through ktmracer21's post about about code P1751 (transmission throttle valve position minimum range performance)...

...but unfortunately there was no resolution or fix at the end! In my case it's happened since I removed the Smarty tuning a few days ago.
The code shows up on start-up after I have cleared the code and then run the truck. I've cleared it twice now. The transmission still shifts fine, and no second gear starts or anything like that.
My truck has DTT transmission parts, the DTT shift enhancer as well as their voltage regulator (about 8,000 km). I've recently switched to the GM solenoid and changed the sensor. There have been no issues until I removed the Smarty.
Any ideas are welcome. just get the feeling something electronic needs to be reset or recalibrated, not sure now!
