I've got a 2002 MPV, that's having the hard shifting and stumbling that others have talked about here. I had a (partial) fluid change, that helped somewhat. I've located a technical service bulletin (US Bulletin No: 05-001/04) relating to reflash of the transmission control module. There's no indication (under hood sticker) indicating that my car had this done. The TSB says labor on this is .7 hour.
My question is can any shop do this? any transmission shop? what should I expect to pay for this (I'm in San Jose). Thanks
