Hi I have a 1997 Toyota rav4 awd. It needs a new engine and I'm looking at an engine out of a 1997 Toyota rav4 4wd. They are both automatic. Will these engines interchange? I am also looking at an engine out of a 2002 rav4 4wd also an automatic. Is 2002 too new to work with a 1997? Please let me know what you figure ASAP as I only have till the 20 of feb to figure out to buy one of these of not. Thank you:) have a good day
