I know and have read a boatload of post about part of the issue im having. I have a 2001 dodge ram 1500 with a 46re trans. The valve body that was in their before was acting up,(stalling when i would slow down and turn, i could start it in any gear, rpm flucuating as i would give it gas and would not engage the gears ect). So i bought a valve body off a transmission place online and its identical from the one i took out. I got the new VB in last night and now I have reverse which works great and 1st gear which feels strong but no other gears. The issue is that it will not shift threw gears automatically OR manually. Everything ive read was that others have been able to manually shift theirs in to other gears but by god my wont do it. Ive disconnected the line going to the throttle body and still no change. We put it on a scanner and all the popped up was p1899 P/N which should have nothing to do with this. I tried what i could, reving rpms high and shifting, feathering the gas to try to get it to shift. Im at a point that i dont know what else to look at. If any ideas or anything it would be a big help.
