Good afternoon, I have a 98 b4000 4x4 automatic. I just replaced my gem mod with pn XL5Z-14B205-EA as my speedo was not working. I've replaced the sensor on the diff and side of trans with no results. After I swapped the gem mod out this time, when I give it a little throttle the speedo will stutter and jump to 120mph and kill the truck. Would anyone have any info on what to look at or for? It idles fine but when you give it the gusto it just dies.
