I am going to have to deal with at least 2 FWD Mopar transmission rebuilds in the future. I want to grab a junkyard tranny, rebuild it and swap.

BUT

I am not sure about how to pick the right Junkyard transmission. Rather than ask 500 questions like will a 90 tranny work in an 84, will a 4 cylinder work behind a v-6 etc etc etc.

Is there a good website or resource for Identifying FWD Transmissions and hopefully interchangeability between model lines?

I only need it for Mopar stuff.

If it were rear wheal drive it would be a no brainer.

Thanks
