Might I recommend NOT using a Jack's transmission? If you are curious about the quality control, reliability, performance, and customer service, go to the search button and see for yourself. Although I have not placed an order for one yet, Sheptrans.com is the place you want to be shopping at. I have personally dealt with John on several occassions over the phone, and placed orders with him. His quality control is awesome, and the customer service is un-matched by any other "DSM" shop, in my opinion.
