This would seem to, at least, confirm that the problem is with the control unit, not the transmission.

I explained to them about my previous repair and then they said, OK - they would replace the control unit (part # 996 618 114 02) which would cost about $3500.
Leading evidence: 'control unit, not the transmission' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, the most frequently mentioned possible cause is 'control unit, not the transmission' (1 discussions; 0 report identifying it and 1 suggest it). The most frequently discussed action is 'Replace control unit (part # 996 618 114 02)' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

My local trusted shop reset the adaptations, but said it might not fix the problem permanently; and, if not, I would need a new control module.
These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

It did fix it for two weeks, then the problem came back.
I started getting a momentary acceleration hiccup at exactly 200 rpm, in manual or auto. My local trusted shop reset the adaptations, but said it might not fix the problem permanently; and, if not, I would need a new control module. It did fix it for two weeks, then the problem came back. This would seem to, at least, confirm that the problem is with the control unit, not the transmission. Apparently only the dealer can program a new module, so I took it in. They called me a couple days later and said I need a new transmission. I explained to them about my previous repair and then they said, OK - they would replace the control unit (part # 996 618 114 02) which would cost about $3500. I had already priced the replacement part (996 618 180 07) at multiple sources for (best prices) under $1600. Those sources supposedly searched by vin #. The part number the dealer gave me, according to all the suppliers, was for an earlier model tip (at least 5 years earlier). I went to the dealer and watched the service manager search for the part through his Porsche software and it did come up with the older number. He says the new number is for an all wheel drive, but every supplier I have contacted says it is for the 2WD model. I am not very confident of the dealer's competence at this point, but they said they would be fine with installing a part that I purchased. Any ideas about how to confirm what the part number should be?
Pull the old part out. Porsche always stamps a P/N on major components. Of course that means you will have to order and wait for the new part. Is it possible that the Porsche dealer quoted you a price on a OE Porsche replacement part, and the other are not OE Porsche parts?
As far as verification of the P/N, perhaps look through the PET or search here

Thanks DBJoe996-
I already had checked with Auto Atlanta (and about seven other suppliers) and they all agreed on the part number. However, you're right - the best way to check is to see what's in the car right now. I asked the dealer to do just that. I'm waiting, but they don't seem to be much motivated. Also, although a slim possibility, there's no guarantee that part in the car is the right one, or that the less expensive newer control would work just fine.
Finally the dealer got around to checking out what was in the car - the part number was 996 618 180 06, which was exactly what it should have been according to every supplier I have contacted (and not what the dealer said should be the right part number). The replacement part number (if anyone cares) is 996 618 180 07. Since it was not the part that the Porsche parts software had listed, the service manager then went on the internet to search for the part and proudly called me to tell me what I had already found out a week before. I'll order the part this weekend and it will cost about a third of what he said they would charge me. There are, unfortunately, some things that only the dealer can do, and this is one of them. I am told by my trusted mechanic that they guard the codes that make this part function so nobody else can do it. I'll bet they can install and program it in less that an hour. It'll be interesting to see this bill.
I'll tell you that I live in Arizona, but I don't want to bad-mouth the dealer - I'm sure I'll have to deal with him in the future and I need him on my side, even if I have to keep him straight from time to time.
One more thing - I'm brand new to this forum and don't really have any Porsche friends, but I want to say this: This is my third 911. The other two were air cooled, 5 speed manual. I've had my 996 about a year and a half, it's got 95,000, and it's still a beast anywhere above 3000. (Never drive these in automatic - I'm sure that's what messes up the ATCM and might even be hard on the IMS bearing) . I could give a damn about round headlights, and what the heck is wrong with paddle shifting? I drive it every day - love this thing!
