I was once quoted $3,000.00 for a new transmission by a dealership. The car, a Volvo 240, actually needed a $300 solenoid replacement. Hopefully people here can get you a reasonable repair. Seriously, though: shun that dealership.

PLEASE don't PM me with Leaf questions. Just post in the topic that seems most appropriate.
