This is going to be very very vague. 2005 Dodge Neon sxt automatic transmission; bought another (crossing fingers) same year. swapped it out and hopefully all connection are correct. But now won't start not even a click. All electronics turn on, I need ideas as to what might be the problem, what could i have over looked or need to check again. Very frustrated.
Off topic where can I send someone to see the installation of a transmission install so they know what they are doing? or an idea of what to expect. Thank you for looking and I hope someone can give some very needed help

 

Welcome to DF! I will move this to the Neon section.

 

I recently swapped out the trans in my Neon. Seems like it would have to be something involved in the trans swap. I would go back and double check eveything you did. Could be the battery ground behind one of the bellhousing bolts or the wires on the starter.

 

Thank you will try to double check every thing without dropping the tranny.
