Hi. I have a 2003 Saturn Vue 2.2 AWD CVT transmission. The transmission is bad and I can get a good 2004 awd cvt for it very reasonable price. Only the 2002 and 2003 are exact fits from what I have read. What else would I need to go with this transmission. I was thinking the TCM and wiring harness and maybe the ECM also. I have to go and look at it because I may have to change a mount too! Any help would be appreciated. Thanks.
