There are just too many to list....
You need a new torque converter. Common. Do a search, there is a TSB about it. I've probably done nearly 100 of them by now.

Typical for a failed TC to do damage to the trans? Especially if its jerking?

Sure, many of these Passat ZF transmissions fail early. Lots of threads on it here.
Thanks for the response, bought a 05 Passat with bad torque converter after about 30k on a rebuilt converter and trans, but it sounds like once it started acting odd he parked it, 2 months ago. I think Im going to Sell the Trans and buy a manual conversion kit. I do have the paperwork for trans rebuild looks like they used OE components. .... Reasonable to think the trans is still good, he drove it about 30-40 miles after light came on. then once he felt it acting up one day parked it for good.....I don't want to give anybody a bum trans...Only the 1 code for torque, I guess I should probably have somebody w/ vag com hook up and see about trans?

The issue is that a lot of the time, some dumbass transmission shop decides to rebuild the whole unit (along with a rebuilt converter) when all the thing needed was a new converter. And once that hack job gets done, the transmission is a rolling time bomb. We see this here all too often. And of course wrong fluid, and/or never changing the fluid (ZF says every 100k km).

While I despise self shifting transmissions, both of my ZF slushboxes have been well maintained and are in good order. 190k and 220k, still kicking. While no slushbox is a "forever" transmission, I'd say these are as good as any if people would just take proper care of them and IF the need for a converter arises, a new converter gets installed properly.

AHH gotcha, well it was done by A German Only Trans Shop, even the owners name (printed on the receipt) seems to be german, So I'm hoping/thinking its good, Im gonna just try and sell locally that way if they have any issues I can resolve easier and not spend a couple hundred in shipping alone yada yada.
Thanks Guys! Now i just need to find a good Conversion kit that wont break the bank....which I already did buying the car haha
