ParadiseMJ Posted January 31, 2018 Share Posted January 31, 2018 I've been "out of commission" for about the last 6 mos. due to some shoulder surgery and some wrist surgery. Haven't been able to do any work on the truck, but I'm on the mend and itching to take care of some issues. My AW4 transmission works great, shifts through the gears, downshifts through the gears. Kickdown works fine too. My problem is it will not shift from D to 3 manually or from 3 to 1-2 manually. Like I said, I haven't been able to climb under and look at the adjustment. The last thing I did under there was to adjust the transfer case linkage when I popped one of those little green bushings out of the TC shift arm. Would there be any other reason the gears wouldn't shift up or down manually if they were working otherwise (automatically). Link to comment Share on other sites More sharing options...
HOrnbrod Posted January 31, 2018 Share Posted January 31, 2018 Pull the TCU fuse and try shifting manually. I remember you changed TCUs and/or transmissions awhile back... Link to comment Share on other sites More sharing options...
