Get another quote.
You can probably get another good condition used (with low mileage) transmission put in for much less...maybe around $1500??

 

I also suggest getting another quote. The used transmission route is an alternative, but you run the risk of running into another troubled transmission. If you are able to have a complete history of the used transmission or perhaps a warranty on parts and labor for X mileage, that would make it less risky.
