I have a 2003 Passat with 109k miles on it, automatic tiptronic with 4 motion transmission. I noticed the other day all of a sudden it started hesitating when shifting from 2-3 and 3-4, and it occasionally 'jumps' a bit when at idle in drive. Is the transmission doomed to be replaced (which exceeds the value of the car's worth at this point), or have others experienced this with a more reasonable fix? I literally just need this car to get me through 77 more days...

Hello,
It sounds as if your Automatic Transmission is having issues. The first thing to do is check the Automatic Transmission Fluid (ATF). This is covered in the Owner's Manual (should be in your glovebox??).

If the level is low, it will cause issues. Your ATF should be serviced every 30,000 miles.

Possibly. Check for the proper amount of freon in the system. There are pressure sensing switches that stop the compressor as a safety measure.

Is it auto?? Needs to know you are not starting car in gear

Sounds like the shift cable is damaged or loose. The cable connects to the shifter under the center console, and runs down to the left side of the transmission. It connects to the transmission near the left transmission mount. It is possible that the cable popped off of the shift lever on the transmission, or there is a clip that holds the cable to the trans that can come off.
You need to have somebody somewhat competent in car repairs take a look at it. There's very little chance there is anything wrong with the transmission itself. It shouldn't cost too much to fix.

blue is oil
White is coolant/water It will also smell kind of sweet
black is fuel

If you don't drive your car very many miles or let it sit for days/weeks at a time it is most likely condensation in the exhaust. Take her on a nice 50 mile brisk drive and see if the problem clears up. If it does think condensation if not you will need to dig further.

Sounds like the whole shifting unit. It has a printed circuit strip unit that usually goes bad or a switch on the side of the transmission. What code is showing? You need to have it scanned at your VW dealership to correctly diagnose your exact problem

2.7 synthetic Mobil1 ATF oil, you need an oil pump to pump the fluid from the bottom of the transmission.

im having this problem with my '03 jetta. No response when i shift right. and i get this buzzing noise when i shift into reverse.

SORRY THERE IS NONE. (NOTICE NO DIPSTICK?)IT HAS TO BE REFILLED BY A STATION OR DEALER THAT HAS THAT EQUIPMENT..

the switch in the shifter lever is most likely worn out or miss adjusted remove the cover from around the shifter look for two contact switches where the up down shift is press gently do they click no replace them yes move the closer to the strike plate
