This VW's transmission suddenly started slamming the next gear. When shifting to 2,3, and 4 gears it will hesitate to long before dropping it into the next gear. So, when it's time to shift into the next gear it pulls it out of the lower gear and rrrrrrooohhhm bang! into the next gear! Ouch, man it does not sound pretty. It slams the next gear, unless you quickly let off the gas. If you let off the gas it'll quietly drop it into the next gear. Especaily when it's cold. After it's warmed up it's ok, unless you take it over 3,000rpm. Then you got to be really carefull.
I just changed the transmission fluid for the second time.
First time, I used a cheaper Wolf's Head trany fluid put in that "met VW trany specs". The trany was fine up to this point. However, my buddy mechanic didn't know there was a filter to change, and he didn't drop the pan etc.
Now everything was fine up to that point till after that I took it to another garage where they tuned a HAFC that garentees a 50% increase in mpg. They don't do anything that would concern the trany besides putting it on a dyno. After leaving this garage is when this transmssion started slapping the next gears. It looks like they might have done something to it, like maybe over heating the trany, or stressing it more than it should have been. They do some fine tuning, but nothing with the transmission, besides putting it on a dyno. So it kinda looks like they might have done something to it, maybe just coincidence. It could be that it's coming from the aftermarket transmission fluid. Although it was brand new trany fluid. It doesn't seem like it'd be either really. It seems coincidental.
So, what's my problem?
I had a VW mechanic change it again, (just yesterday for the second time.) I asked them to take out all of the aftermarket stuff, and check for any metal shavings or something that would indicate that something is going bad with the transmission. They said everything looked fine. They drove it, and immediatley had they same results with the VW trany fluid, so they recommended me go to a VW transmission specialist.
I had a tuner go over the wiring. He found a loose ground wire and grounded it properly. The transmission has been shifting correctly ever since!!! It felt like a mechanical problem, and acted like a mechanical problem, but it was just a loose ground wire.
Let this be a heads up on VW transmissions!
Thankfully it was only a loose ground wire and not a $5,000 trany!!

I have the same 2002 Passat with Tiptronic transmission and have changed the transmission fluid as well and had smoother transmission shifts. I never had the engine rev high when accelerating, however. You mentioned driving up an incline. Perhaps when changing the transmission fluid you didn't add enough. The procedure for adding transmission fluid is very critical for proper fluid level. There is a large hex plug (I think 17mm) in the bottom of the transmission pan that if removed, no fluid should come out if the car is level and the fluid is at or below 113 degrees F, and the car is RUNNING in Park. That's because there's a riser tube in the hole where the hex plug was removed that rises up to where the top of the fluid level should be under certain conditions mentioned below. DO NOT GO UNDER A CAR, OR LET ANYONE ELSE GO UNDER A CAR, UNLESS YOU ARE SATISFIED WITH YOU TAKING YOUR OWN SAFETY PRECAUTIONS. IF YOU PERFORM THE FOLLOWING PROCEDURE, YOU DO SO AT YOUR OWN RISK! Let's talk about how to drain the old fluid. Run the engine in PARK to warm up the transmission fluid to a temperature that won't burn you. To drain out the fluid, you must remove the quantity (27) Torx 27 (T27) cap blots from the rim of the transmission pan and drop the pan. I highly suggest replacing the filter and pan gasket. I used an AMSOIL recommended ATF transmission fluid (go to the AMSOIL website) instead of the very expensive VW OEM transmission fluid. I have had no problems with the Amsoil fluid in my 2002 and 1999 Passats with over 100K miles on the Amsoil fluid between the 2 cars. When adding fluid, start with NOT running car engine, make sure car is level (use a magnetic level on the transmission pan both front to back and side to side) and then add fluid with a syringe or gravity feed up into the riser tube until fluid overflows out hole. Now, if that's all you did with your transmission fluid change then you will be low on fluid! More fluid is needed! Next, have someone turn on engine and WITH THEIR FOOT ON THE BRAKE AND THE EMERGENCY BRAKE SET AND NO ONE UNDER THE CAR go through the gears slowly (about 5-10 seconds per gear) and then leave in PARK, still with the engine running. The engine has to be running to keep the torque converter full of transmission fluid. Now, add more fluid as described below and wait for fluid to overflow out the hole all while the fluid is at a theoretical 113 degrees F, readable with a VW VAG diagnostic tool or a Ross Tech VAG equivalent, which I now own, but not when I changed fluid. So, what I did is use my hand on the bottom of the pan and estimated what 113 degrees F was. (This "human temperature gauge" procedure worked well for me at the time and both cars have been shifting very well ever since.) THEN, WITH THE ENGINE STILL RUNNING AND IN PARK, REINSTALL THE 17MM PLUG IN THE TRANSMISSION PAN. You now have the correct transmission fluid level in the transmission! I hope this helps you and others! Remember, SAFETY FIRST!
2001 Volkswagen Jetta TDI THE 5 SPEED AUTOMATIC TRANSMISSION At the bottom of the automatic gearbox (tiptronic) you will find one threaded plug on below surface, (follow red arrow in the picture below). This is for emptying.
The oil level threaded plug is placed on the car front lateral automatic gearbox surface, (follow yellow arrow in the picture below).
The filling oil plug is placed on the upper automatic gearbox surface, (follow green arrow in the picture below).
Automatic Transmission Fluid (ATF) checking: 1. Requirements for check: 1.1. Vehicle standing on level surface. 1.2. Transmission must not be in fail-safe mode. 1.3. Shift lever in "P" position, parking brake applied. 1.4. Engine idling. 1.5. Air Conditioner and heater OFF. 1.6. ATF temperature must not exceed 104 Fahrenheit degree (40 Celsius degree) at start of test. 1.7. Automatic gearbox oil capacity: 2,5 liter. Only ATF with VW designation may be used. Do not use any lubricant additives. 1.8. Automatic Transmission Fluid ATF - part number: VW G 052 990 A2 1.9. An ATF level check when transmission oil temperature is too low results in overfilling, when too high results in underfilling. 2. CAUTION: Too much or too little ATF will affect the operation of the transmission. The ATF level must be checked at regular intervals. Don't forget to rate my response. Thanks!
Need more clarification when driving and park. Happen to vw a lot with no solution.
Could be electrical ( Tcm + Wiring conector, ECM) ( fluid change fluid+filter add lucid tray oil) or mechanical.
Rattle could be engine or evap thing located under or next to air filter. Alternator also.
The engine you speak of is know for sludge build up problems by VW. They've even made recalls base on what I've heard. Check oil circulation and how to fix oil circulation problem.
Drop the the oil pan and clean filter screen where it sucks in oil. Other things related need to be unclog..
I have the same problem with my 2003 Passat TDI. There is a magnet in the gear selector to engage and disengage the manual shift. I live in Thailand and am waiting on the VW dealer to locate one. If you are a little bit hands on you could possibly do the repair yourself. the replacement part is the plastic that slides up and down when you select your AUTO gears and of course to pull to the gate to engage manual shift. The magnet is part of that plastic replacement part. Cost 2000 baht which is about 42 English pounds.
Did you ever find an answer to this problem? I am interested because I also have a 2003 V6 4-Motion Passat and am having similar issues. I only have 86,000 miles on it, but I'm sure if I have to end up replacing the transmission it would not be worth it. I'd be interested to hear what ended up happening with yours. Thank you!
My 2004 Passat 1.8T 4motion has the same problem. Took it to the dealer. I thought it might be a software issue as there was a service bulletin for a similar issue registered at the NHTSA.gov website. They claimed they did all the sensor checks and found nothing. Then they said the tranny was shot and for a mere $5,000 I could have a new one. I begged to differ so I called VW itself and described the issue. Their customer service rep was not even up to the type of car this was and had no idea about what I was inquiring. Those people are trained to be obstructionists by VW. I tried to get this problem elevated to a higher level and was told they were the end of the line. Sadly we're on are own with this manufacturer. They simply deny, deny and deny. I'd suggest you lodge the problem with the NHTSA under defect investigation. Maybe some day they'll find it was a design or manufacturing flaw, just like their coil issue.
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
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
