Automatic transmission when cold will hesitate or not catch at all when putting into drive. Putting the car into 1st, then moving it to drive will usually work. Shudders when coming to stop after heating up at times. Mechanic says it needs a transmission rebuild at $3000. Failure of transmission control module and cascading to the master control module caused the transmission not to leave the park position, that tow and repair was $300 about 30 days ago. There are hundreds of complaints on the internet about this transmission failing repeatedly, a faulty design. We need a recall from Volkswagen to fix this design failure.
I purchased a 2002 vw in 2005. I had a car accident in Dec '08. Shortly after the collision place repaired my car. The vehichle started misfiring and essentially wasn't drivable. The control arm bushing were replaced $800 (at the vw place) and the service dept said that they would check fluids in particular the transmission fluid. I was told that the transmission didn't have the updated tranmission control module (tcm) and had to replaced ( $700 part and 300 labor) the service technican did state that this was the first step in diagnosing and correcting the problem and that that this was a known issue but not a recall. Well $1000 spent on this still did not fix the problem and now they say the next step is to replace the transmission on a car that has 87k miles another 4k. Well, I can honestly say that vw is unreliable and does not stand behind their name, product or reputation. This is shameful. I am very dissafied and learned that there are numerous customer complaints on the web related to transmissiion, tcm on the vw 2002 - 2006 model. Vw should be held liable and compensate for this a defective/inferior product.
2002 Jetta vr6. Transmission control module (tcm) became faulty after mil light turned on for a emission related issue covered by a recall. Technicians failed to identify the faulty tcm after four trip to the shop. Last trip I showed them a TSB related to the tcm and now they agree that the modual is faulty. Worst part is it destroyed the transmission. The car has been hard to control in stop and go traffic as shifting is not smooth between 2nd and 3rd gears. Car has initial no acceleration/power followed by fast jerking shift into the 3rd gear with high acceleration. Car maybe out of warranty but identifying this issue is not easy for the automotive technicians and this part when it fails leave the car in a state that is hard to control or manage. Dealer only offered to credit this last diagnostic fee towards the $4700 repair which now include not just the tmc module but also the whole transmission. This is after having spent close to $1,000 trying to identify and fix this issue. Not sure if it was related to the mil light issue covered by the recall but since then the tmc had not worked correctly.
