Hello folks, My mother in law has a 2000 durango with a blown 4.7 engine on an auto trans. will a 5.2L fit in it on that same trans? And all the computer stuff work? Thanks

 

The 4.7L uses a different transmission than the 5.2L

The engines also have a bunch of electrical differences, I doubt you would be able to use the same electronics on the 5.2 as on the 4.7L.

You would probably be better off pulling the engine out and reabuilding (depending on what killed the engine) it then putting it back in. Or you might be able to get a 4.7 from a junkyard fairly cheap seeing as the engine has been around since 1999.

 

Thanks for the info, was hoping it would give us more options. But oh well, 4.7 it is then. Thanks again

 

Definitely rebuild the same motor or different 4.7L. You are talking about throwing allot of money into it for not much power ratio.
