You are looking for a whole transmission?

Depends what is wrong with the transmission, and the condition. If it is something major like gears needing replaced ($250+), your looking at a lot more money. Possibly transmission fluid needs replaced for easier smoother shifting, which is no big deal ($5-10). Hopefully the whole thing will not need to be replaced or your looking at a few thousand dollars!
This would depend on whether you are looking for a used or new transmission. If you are looking for a new one, I would suggest contacting the vehicle manufacturer or a parts company such as AutoZone. If you are looking for a used transmission, websites such as Craigslist and Ebay can be very helpful. You can also call your local junkyards to see if they have the transmission you need.
