I have a 2001 Neon SE. Has an automatic transmission. What was the factory transmissions in this car? I read it was the A413?? Would like to know so I know which rebuild kit to get

I'm also wondering about and SRT 4 swap.. I wanna keep the auto trans.. trying to make a sleeper.. what's needed to do this? Will the auto trans bolt up?

I've tried looking on Google but not finding EXACTLY what I need to know..

Thanks for any info
