Transmission problem
2001 Chevy Silverado 6 cyl Two Wheel Drive Automatic 160k miles

originally transmission was not shifting gears properly...internal transmission computer, along with all the shift solenoids were replaced (bought from a junk yard )....this improved shifting from before; however, what actually improved the problem was the manifold gasket was replaced (it was leaking a lot)....it was working okay for a couple of weeks...now it shifts okay on cruisng speed but when gas is floored down the passing gear does not kick in well....rarely sometimes it goes in well, but majority of the time it does not, rpm goes up slow, as well as the speed...oil level is fine ...transmission seems to work okay but it sucks it takes long to pass a vehicle...can you help me?
