Transmission Probelms 4t45e

Ok about every 50 starts I will start up the car and put it in drive andmakes a loud bang noise through each gear. I shut down the car and restart it and it goes away for a little while. I have had the car scanned and there are no codes and check engine light never comes on. Other than that when it is driving normal (Not Banging). Say I'm going like 45-50 and stomp the gas 1-10 times I do it seems to shift right. 9-10 times it jumps only 1 rpm I know its not normal I have had the cr a while. Its really killing performance. Jumping from 3 - 4 rpms is not doing anything. I know something is wrong I just don't know without codes. When I'm on the freeway say about going 60 mph stomp on gass just 1 rpm and doesn't go any where. Also say I'm driving really fast and have to stop at a red light really fast. It feels like its in gear trying to push me into the intersection than I have to put it into nuetral. It doesn't do it all the time just sometimes. Has anyone had a problem like this and what should I do. My car is stock for right now. Feels like a downshift problem. I have parts siting in the garage trying to figure this out first. Any help is appreciated thanks!



No one knows anything?
