I have a 1999 crew cab 454 dually pickup and started to get a miss or slip in it on a hard pull up hill in over drive had trans checked and flushed no problem found but strated happen in drive to, so i installed new fuel filter and checked the plugs and wires the wires and plugs looked good and were replaced at 50,000 miles and the truck only has 74,000 on it now and the trucks only acts up now in over drive and only on a steady pull if you give more gas it doesn't get help or hurt but if it shifts down in passing gear its ok any help would be great thanks Josh |
