03XKR surge under constant speed when cold?

I have never head a supercharger before and I thought I read something before that this may be normal:
When cold, and you keep a constant pressure/speed on the pedal, car surges slightly (engine sound/pitch and revs change a bit).
Is this normal? If not thoughts?

OK so how does a torque converter fail at 60K? Never in my life have I seen or heard of this? Suppose this is the culprit, 1700$ for converter and 400 for install at dealer plus parts like orings, fluid, etc....close to 2500$
What EXACTLY causes the failure or need to replace and when you replace it wont it just happen again?? Was curious WHAT was the root cause of the failure with such low mileage? They say lining in the bulletin, what changed in the replacements?
Also I have NO CODES.

Few questions, yes I didn't know they did rebuilt converters, but they are available for $500....
1. If I don't fix it, what will eventually happen?
2. Any special tools needed for the job? JTIS mentions a few but are there homemade tools that can be used? Or is this a dealer job?
3. It does it BOTH in sport mode and regular mode, doesnt matter, so should I try and ECU reporgram/check first?
4. Who else has had this happen to them and what was their outcome?

If it were me I would first try a few things before diving into the transmission converter. First I would clean the TB and then add a can of BG 44K to a full tank of gas and drive the car. You have no codes and no confirmation that it is the convertor or not. When was the last time the spark plugs were replaced? As for the tools, any good transmission shop could do this.

I just cleaned the TB and MAF about a month ago, was a little dirty but not bad.
This car was dealer maintained and the plugs were changed at 60K per the maintenence schedule (I think thats the mileage I remember?) - now I have 67K on it.
Yes no codes other than the typical P1111 or whetever.

2. Only to the extent you will have to have some way of holding the engine so it doesn't fall forward when the trans is separated, and what ever you may need to actually separate the two. Aluminum engine, aluminum trans, steel dowel pieces. At times they want to become one with corrosion.
3. In my opinion it is ALWAYS advisable to do the reprogramming, adaption clear and adaptive drive cycle per the bulletin as the first order of business. Just so that is eliminated. Once in a while, you can stop there; but most times it takes the converter.
4. As you can infer from above, you are not the only person that has seen this movie; I think the outcomes are covered as well.
For the most part, you seem to have covered the other bases pretty well, too. So you ought to have a game plan now.

no slipping from mine, thankfully...and hoping to keep it that way. I've not heard of any come through these forums, at least on the xk8-r side, though I don't read every s-type thread that is generated either, nor xj8-r. Keep us informed, if for nothing else but to keep you sane, and to share your experience with others who may learn from you.
