after transmission installed truck wont star
 

My transmission went out so I put another one in and now truck won't start it will turn over a lot so took out transmission to make sure no wires pinched and that it was lined up good still no start so I took out my torque converter and re hooked up transmission and I had to jump it off but it started right up so I put torque converter back in and truck won't start. I got battery checked out its good and went and got new start to make sure I'm so lost thanks for your time
