If you check, the replacement the dealer installed in your car was likely a "certa" unit which is another word for a factory rebuild. Therefore a rebuilt transmission will not be anything "new"
If you press the issue, you will likely get Jag to replace yours with another certa unit. You may need to make a bit more "noise" though.
In choosing a private shop to do this work, ask around and see who has a really good reputation."Branded" shops are franchises and as different as dogs and cats when it comes to quality. If you have friends with a similar car, see who they have used. If you use a private repair shop ask who they "job" their trans work out to.
It may take a bit of shopping but you likely will find someone who can do the right job for you!

unfortunately when that code, and that gear box fault light comes on, its pretty much game over for the transmission. It only a matter of time before performance of the transmission gets worse and worse. BUT that transmission is VERY easy to replace, i would check out a few trustworthy independent shops to give you a better price! I am usually a die-hard dealership, having been working at this jaguar land rover dealership for the last 2 years, but you are pretty much for sure going to be a cheaper price on the labor and like i said it is a pretty easy task.

My only precaution MAKE SURE IF YOU GETTING A USED TRANSMISSION THAT YOU GET SOME TYPE OF WARRANTY ON IT. Too many times have I seen customers loose thousands of dollars paying someone to put a used engine or transmission and have it fail almost right away.
