Jetta Transmission Problems and Questions

  • Is your car an automatic?

    If it is then have a shop check your transmission. Sounds like there's a problem with the transmission.

    More than likely it doesn't have to do with the timing belt or oil leak.

    Here's some info about oil leaks in case you're interested in knowing: https://www.yourmechanic.com/services/oil-fluid-leak-inspection

    I have the exact same problem with my 2003 Jetta wagon TDI. Did you ever find out what it was? I would appreciate any feed back. No technician I've talked to seems to have a clue what it could be.

    The issue was a faulty TCM (transmission control module) and the transmission wiring harness.

    The error code causes the initiation of "limp mode" in the transmission. This restricts the transmission to 3rd gear to prevent damage until issue is resolved.
  • I am having the same problem now with my TDi. It started back in Jan. 2013. Did anyone ever find a fix for you? I'm tired of not having a ride.

    I have been having the same problem with my car with less than 66,000 miles. It randomly shifts into nuetral usually around 3rd gear and has some electrical issue that drains the battery if I do not drive it for a few days. The VW Dealer told me to replace the transmission for $7,000 and see if that fixes the problem. I have taken it to several other people and have been told it is the transmission, mechatronics unit, unknown electrical problem or no idea. I had the transmission fluid replaced and reflashed but did not solve the problem. I also wanted to see if anyone knows if this is the same transmission as the Audi 2002-2006 A4 or A6. They just settled a lawsuit stating the transmission was flawed. It would be nice to know exactly what is causing the problem before I start throwing more money at the car.

    If the radio was installed rite there is no possible way the radio caused the computer to fail. Maybe if you shorted 2 wires together. If you herd that from the dealer that is false. Check Fluid get a clothes hanger an put in the hole of the trans paint it white and measure 2 in and mark it thats full mark

    German engineering is great
    I own a 2003 Jetta And it is the Best, no problems just changed the water pump and timing belt 102000.
    Transmission shifts good i rebuilt the valve body all new electronics at 100000 Fluid still clean.

  • I have a 2002 Jetta 1.8t with 5speed tip-tronic automatic transmission that does the exact same thing! And I'm on my second transmission and it's doing the exact same thing again! NEVER AGAIN WILL I EVER BUY A VW/AUDI/PORSCHE with an automatic. This is my second Jetta and my other one had a slipping transmission too!

  • Yes , those transmissions are well know to give a lot trouble.

    The way I use to correct them is by installing a shift kit from , " Trans go " along with a wiring harness from " Rostra presicion controls , Inc " P/n 75 446 from " Transtar " .
    The factory wiring harness is a very , very bad unit .
    The factory should be recalling those trannies .
    Why they do not do it ? . Because it will cost them a lot of money !.
  • SO i have a 99 jetta manual transmission 2.0 and onm my way home from the store i could not go into reverse . i got the car home fine 1st thou 5th worked fine the next morning on my way to work it would shift in to 1st but would not go so i tried 2nd and nothing it got 3rd ok then 4th but not 5th i popped the hood to find that shifter cable was broke at the transmissin so i took off the broken part put a bolt to hold it in place thought problem sloved nope still no 1st 2nd 5th or R anyone that got any ideas

    Replace the broken shift-cables and adjust the linkage.
  • Hello All,

    I thought i'd share my two cents on this issue in case someone might be having the same issue as me. Let me begin.

    A year and a half ago I purchased a used 2005 Jetta GLI MK4 edition. It's an automatic with tiptronic. I fell in love with this car and the deal was too good to pass up. The car on had 62k miles on it, competitively priced, and was in good shape.

    I bought it from a used car dealer and sadly turned out to be a nightmare/lemon. I had multiple problems with the car but the biggest concern happened 7 months after owning the car. One day I couldn't reverse. I'd sit there revving my engine and nothing would happen until it'd finally lurch backwards (quite dangerous, really) so I finally took it to a mechanic and he thought it was the oil but it was a wild guess. He was going to charge me roughly $300 to check if it was the transmission oil. I, of course passed. He did, however, told me a quick fix was to rev the engine with the handbrake until the right gear kicked in. While driving, everything was fine. The gears would shift smoothly like nothing was wrong; It was just reversing that was a [non-permissible content removed]-show. I remember having to put the car in neutral to reverse. When you're by yourself... this can be a hassle and stupid-looking. I'd be happy if I ended up parking on a slope so if I had to reverse, the natural slope would allow me to go.

    I finally took it to a VW mechanic and ran a diagnostic and came back with bad news. I needed a transmission overhaul. It's not cheap. Some places charging $3500-$5k!! I found a ghetto mechanic and he fixed it for $1500.

    Thought my woes were over but a few months later it started hard-shifting (Basically shifts hard switching between gears). I took it back and he fixed it (my tranny was luckily still under his warranty) and he told me it was electrical.

    Fast forward a few more months and my car is hard-shifting again. Because its late in the day, I opt to take it the next day. While on my way to the mechanic the next morning, my car was shaking violently. Everytime my car was in Drive and I was fully braked, my car would literally tremble violently in place. I left it with him for the day. He calls me and told me I needed to take it to an actual VW dealership so they could check some ECM error.

    The next day I drop $125 for VW to tell me I need a new transmission and a transmission control module (TCM) which would cost.... wait for it.... $7000!!!

    This news was the icing on the cake. I had already spent several hundred dollars on un-related repairs and was being stubborn as hell letting my car go cause I loved it and cared for it. But having a car LESS than 2 years and having so many terrible problems/issues? Not worth it.

    The VW guy at the dealership told me to just fix it and sell it, which is where I'm currently at now. I took my car back to the mechanic so he can fix it but was doing research for a new TCM and couldn't find one and ran into this forum and thought I'd share my story.

    If anyone would like to know how this all turns out feel free to private message me because as soon as I fix my Jetta, I'm selling it off. I know people love German engineering but this is ridiculous. I'd love German engineering too if my car wouldn't be shitting on my every couple of months.
