I have a problem with the 904 auto in the valiant. I brought the box 2 years ago as a unknown and when we pulled it apart for a reco to drop behind the 340 it had a shift kit fitted and a few other mods done to it, we freshened up the box and dropped it in and everything seemed fine until i pull the shifter into first gear when i change to second the box wont shift pull third still wont shift just stays in first? When i takeoff in drive the box shift's normally up and down....any suggestions what to look for?
