'96 Monte Carlo Z34

Hi, I have a '96 Monte Carlo Z34 with the 3.4 DOHC LQ1 V6 (Talk about a nightmare!!) Anywhoo, I have been experiencing a problem with my 4T60E shifting up into a higher gear at the worst times(hill climbs, easy takeoffs), even when I physically shift out of overdrive! It shifts perfectly under wide open throttle, but regular city and highway driving has become a pain in the ass and my fuel economy is suffering for it. My '90 Pontiac Grand Prix has the same exact tranny and doesn't have this issue...Please help! :th_angry-censored:
 


It is in the tuning. I have remapped shift tables for it and can set u up with a nice tune while at it. I'll pm you for the info as I see this is a few months back.
