I put a used Trany in my van, Now it wont start? I changed the plug 4 the od, because the old one had a bad??or lose wire, It was runing, when i park it, Took a trans out of a 99/360. and its the same.. would there be a reson in the trany for it to not start?

 

If by "won't start" you mean the starter won't turn...test the neutral safety switch.

 

van turns over, no fire 2 plugs. drove it in shop. R&R,trany. with used one, the other sliped, The thing ran good, its my work truck. thank you..
