Shift Kit On The Allison
 

Hey guys, I didn't know if anyone else has bought the transgo shift kit for the Allison transmission? I installed it today and the papers that came with the kit said expect some bumps and clunks while my transmission is doing "relearn". Well about 2 minutes of my truck running my check engine light came on. So resulting in limp mode. But when I turn it off and let it sit for a minute or 2 It's out of limp mode but shifts extremely hard(up and down) and goes back into limp mode at 3rd gear or 5th gear. So I don't know if anyone has experienced this or what? And how you fixed it. Any help would be greatly appreciated!!
