1. my wife was driving the car (2004 Volkswagen Passat gls, 1.8 L turbo), and it felt like it was having trouble shifting from first gear to subsequent gears. It was sudden, not gradual by any means - the car just started to hesitate when shifting, and the mil lamp was lit...this happened in heavy traffic in the detroit suburbs - not an ideal time to not be able to accelerate. 2. the transmission was replaced under my powertrain warranty (it's my opinion that this was an unnecessary replacement). Upon further investigation, it was found that there was a water leak in the vehicle, and the passenger side floorboard was filled with water, inundating the transmission control module. It turns out that this damaged the module, and effectively rendered the car is not able to be driven. 3. the transmission control module is being replaced, as well as a "seal" that caused the water intrusion (I haven't been able to get out of them which seal was replaced - this can be addressed with a follow-up).

The tcm (transmission control module) failed due to a leak, that is a common problem, I now find out $1300 later on this 2004 glx Passat. After searching for 4 months for a tcm I learn that this is an on going problem 2001-2004, that VW hasn't addressed, but is aware of due to the configuration of a drainage system that causes water to enter the passenger floor board and fry this tcm.which could result in an injury or further damage to the vehicle, due to transmission shifting suddenly and unexpectedly into 3rd gear.

When slowing to a stop transmission/drive train occasionally will demonstrate a jarring and potentially dangerous "clunk" as if the trandmission is dropping out of the car. The car also lurches forward slightly. We have read that some dealers tell their customers the problem is due to a faulty transmission control module. Our dealer, russel VW in catonsville md said they could do nothing, denying ever hearing about the problem. We contacted VW-usa and they said they had no knowledge of such a problem. This is clearly untrue!!! there are complaints of this problem all over the internet. VW is setting itself up for tremendous liability issues should injuries occur because of this problem.

There is a problem with the transmission. The car shifts sharply in lower gears causing severe jerking of the vehicle at times. Dealer "rebooted" the control module but no change. The mechanic at the dealership let it slip that they were aware of this problem and that there is no solution at this time. I can't believe they sold the car knowing of this problem. I contacted VW and complained to the dealership. I was offered 2 months of free loan payments by VW. I recently received a call from the dealership saying that the software problem has been fixed. I am taking car in this week.

Purchased 12/03. Within 2 weeks began to shift abnormally slamming in/out of 1-2nd gears. Drove technicians 3 times before they would admit something wrong. Unplugged transmission module - no fix, replaced module - no fix, then admitted they have software programming problem and engineers are working on it - no fix right now. Has been 6 mos of poor shifting, now likely transmission damaged, still no fix available.
