Hi, i have a 1994 chevy silverado 1500 with a 4l60e transmission. I just replaced the transmission with a freshly rebuilt tranny. But im still having the issues i did Before. It wont shift into 2nd gear Unless i let off gas at about 3500 rpm. And once its in 2nd it is stuck in 2nd. Until i put truck in park and shut it off. It also Idles at 1500 rpm if that means anything. Any help is Appreciated.
