Internet photo not the actual car. Identical though.

Need some help. Have a friend with a 2000 Jetta 2.0 automatic. Sh e is having issues with transmission, car dying at stops, not going into gear etc. Ok here is the current situation. Car will go into every gear but going into Drive, Reverse, and 2nd results in the car bucking against the brakes trying to go forward or backward depending respectively , car also doesnt want to shift. The engine can also be revved somewhat while in gear without change in acceleration as if the fluid is very very much thinner than it should be. Apparently the transmission is sealed so no- one has checked it or replaced the fluid. Ne utral position switch? has been replaced and the speed sensor has been replaced as well. What is the Oppo hivemind opinion based on that? Im thinking she should sell it for what she can get and buy a beater toyota to replace the beater vw.

Can she park it next to a tree during a wind storm?

this may not be the same issue, but apparently the TCM is worth replacing.  shift issues may instead be a solenoid problem.

The transmission is not really sealed and should be changed every 40k miles or similar. If you follow the orange oil filler down to where it enters the engine block and keep going down you will see the top lip of the transmission pan. You might have to look at it from underneath. There is a plug there with a red band that snaps on the plug. Pop off the band and you can pull the plug on top and add fluid. To check the fluid, park on level ground, on the bottom of the pan there is 5mm or similar Alan key, remove that, and fluid should dribble out a little. With the engine running and just starting to warm up (trans fluid should be around 80 degrees Fahrenheit) pour fluid into where you removed the plug until it pours out the drain on the bottom (there is a little tube in there that lets it drain when at the right level).

When I have added fluid in the past I use a big tube that I run from the top of the engine and push it over the filler tube.

To remove the fluid, remove the little tube under the drain plug on the bottom, its plastic. Gently unscrew (I think it is a 4mm) and it will come out the drain hole. Put it back in when drained so that you can fill it back up to the right level.

Side note, these cars have a separate differential fluid fill (no drain). You remove the speedsensor (mechanical) i think with a 24 mm and use the bottom of the sensor as a dipstick.

Low fluid will stop the car from moving forward sometimes, especially if facing hill.  The car shutting off is likely something else,  the fuel filters seem to be easy to clog and is cheap and easy to change (snap on connectors).

First step... transmission info:

Second... Have a look at this link where the issue was resolved by replacing the filter and flushing the transmission fluid a few times :

“Forget” to set the parking brake and roll it down a hill?

I actually had some similar issues with my 850 when I bought it, though not as severe. Volvo also touted a “lifetime” transmission in that car that would never need service. You know what I did to fix it? Service the transmission.

Transmission fluid is pretty cheap, so I think it’s worth a shot. It might fix the problem, but it also sounds like you can’t make it much worse.

One piece of advice - given the age of the car, I wouldn’t flush it and refill it. Flushing it can actually make things worse by disturbing deposits and other crap, which will then float around in the transmission and bind things up. Instead, drain about 25-50% of the fluid (2-3 quarts depending on how much it calls for) , and add that much new back in. D rive it around a bit, say 100 miles or so, over the course of a few trips. Repeat this process 3 or 4 times.

In my case I would drain/add 2 quarts over the weekend, then commute to work in it (about 14 miles each way) during the week, and then service again the following weekend.

Make sure to use the OEM fluid or I Pentosin might make it.  If I recall it is a clear mineral oil, not red regular trans fluid.

I could add some technical stuff, but it’s been covered.

Simple answer: for what it’s going to cost to fix plus what’s likely to break in the next year , she can get something more reliable.  Sell it and get an old Subaru or Toyota or something.
