Re: engine r transmission

pulled codes prk neu switch - throttle position switch if was one of these i figured it would still stall in park- in park accelerates smooth boost rises as it should not familiar with the auto transmission most ive worked on were manuels Didnt know if something with trans could be causing the problem When it shifts into 2nd rpms get to around 2100 then its almost like the engine shuts off but doesnt if you hold in 1st will accelerate to 3 to 4000 rpms no problem When it hits second its all over could it be the speed sensor or is it cable driven? Any input will be very appreciated
