It's real simple. If the transmission shop has an SDS they can do the job. If they don't they can't. 722.9 conductor plate replacement is only the fix for a few issues and is determined by the specific fault codes. I've had indy shops replace the CP's and tow it to me to program only to find out the CP wasn't gonna fix it. I've got no beef with the indy shops but I think you're better off having the diagnosis done at the dealer.
