I converted my dually to 4wd. No issues with my 2wd tranny what so ever. I swapped in a 94' 4wd e4od and transfered the NSS and the solenoid pack from the 97 to the 94 tranny. Now when placed in D the truck starts in 1st but will not shift o 2nd unless manually shifted. Tranny will not go in to 3rd or OD. when I disconnect the solenoid pack the tranny starts in 2nd and will go to OD but will not lockup. Speedo and tach work normal. Now I have a hard ABS light and I've already swapped out the VSS sensor. All wiring on the tranny and VSS check good and a fuses are good. I had the tranny shop check it out and their computer manually shifted through all gears sitting stationary. He said his money is on the dash bezel gauges. I swapped those out and no change. I'm pulling my hair out trying to fire it out
