I have a 99 cummins the one in my sig . I put a new tranny in it from an 02 truck everything worked fine in the truck it came out of. Now in my truck the trans temp light and the overdrive light won't go off I also have no second gear I have to take it to 3200 for it to shift out of first and it goes straight to third gear. And I can't get OD to to work. Any thoughts?

 

your body control module isnt programed for it

 

What does that mean?

 

wrong computer program

 

Sorry I meant what if anything can I do? I've swapped the output shaft sensor and the other sensor below the linkage from my old tranny Do I need to swap the other 8 prong sensor from the old trans and if so how does it come out and what's it called/for?
