As far as I know the Rev-up was used on Manual trannies...will it work on an auto?

Same year 2005

or what would be needed to make it work

 

revup motor in a car that didn't have it originally? Physically you can make it work. but you have to resolve how to electronically control a rev up motor with an ecu that didn't have it before. I'm fuzzy on the differences but didn't revup have varible cam timing on both the intake/exhaust cams while the non rev ups did not?

 

^^^ yes

 

It can be done but very complicated.. Unless an ECU from a revup will work on a automatic tranny ECU and car will run fine with maybe a CEL then it will work.
