Here's a website for you. www.worldautoparts.com. Check it out and find what a good rate is for a transmission. Keep us informed as to your progress. As for the EVAP leak, try tightening the Gas Cap, or replacing it. Run a scan, erase that code and see if it duplicates. If that doesn't do it, then some other things may have to be checked, i.e., vacuum hoses, purge cannister, etc. That's when I run to others more qualified to lend a hand.
