    critical question about transmission fluid leak

    does the passat b5 2000 auto have a transmission dipstick?
    i think i may have a leak and i cant find any way to check tranny fluid levels.

    i checked under my car today while doing an oil change and there was some clear grayish colored fluid on this round ribbed metal part.

    not much, just a drop.
    yesterday while i was driving i noticed power loss.
    the car was accelerating slower as if it were going uphill.
    i hope the transmission isnt low on fluid. someone help.

    my questions:
    is there a dipstick or way to check fluid.

    and does auto tranny fluid look clear / grayish.

    The factory-installed Pentosin ATF is gold colored. There is no transmission dipstick, the correct way to check fluid is outlined in this guide.

    I have the exact same issue. Instead of the gray drop you had under the ribbed part, I had a red drop. I have a B5.5 1.8T Auto.
    I am sure if you leave it parked in the same spot for a few days you will see a small puddle of ATF under it.
    Whatever the issue is, I think we have the same problem. If there are others with this problem or you had it fixed please let us know.

    a red drop wouldn't be tranny fluid unless your transmission fluid is different then the normal gold, or the old dirty blackish color thats shown in the taligentx guide. a red drop is normally leaking motor mounts as the hydraulic fluid in them leak and look red or purple...also theVW G12/G12+ Coolant is a pinkish red color also but I don't think any red fluid should be from the transmission itself

    To the original Poster: I don't see a picture but what round ribbed metal part are you talking about? Clear grayish colored fluid...maybe brake fluid? or Power steering fluid? I'm not sure what color P/S fluid is but I know brake fluid is clearish. As for feeling like you were going up hill, any chance you didnt put in enough oil? It could be psychological but sometimes when I feel I'm getting close to needing an oil change and starting to get lower the car feels like it needs a little extra push on the pedal, but after adding oil it runs better. The v6 (at least 2003+, definitley the ATQ) takes up to 6.5 quarts of oil, my last car took 4, maybe 5 qts and this definitely holds more oil for a 6 cylinder then I think most others.

    i actually just did an oil change yesterday and added a new purolator filter
    and mobile1 10w40 full synthetic and the car still feels like crap.

    when i wiped off the fluid from under the car it was a dirty gray color.
    but it was just a small amount.
    ill try to take pictures tomorrow morning of the exact location.

    i have a 2000 v6 atq.
    i drove the car for 2 hours on the highway yesterday and it didnt break down but i definitely notice power loss and even when i let go of the gas sometimes and the car starts slowing down, i can feel it grinding down.
    not like a grinding noise but its more rough and it feels like it may be transmission related.

    the pic shows a cup of new oil and dirty oil.
    the dirty atf definitely looks gray to me.

    theres no way mine is gold, as the car has 116k and the atf has probably never been changed in its life.

    update:
    here are two pics of the leaks i found.
    the coolant leak is leaving drops of red on the hose that goes to
    the oil filter. the thick black hose.

    the 2nd pic is the round ribbed metal piece that i found the gray fluid drops on.

    any ideas anyone?
    also today i just checked my oil level and the dipstick is halfway between the two orange parts. when just two days ago i filled it up to the top with 6 qts of oil and a new filter.
    strange? anyone know whats up?

    Look up above where the coolant drips are on that hose, if you see nothing I would suggest replacing those old clamps with some screw type hose clamps. Dried G12 turns into pink crust everywhere it is if you have had the leak for a little while. Kinda makes it easier to spot problems.

    Is your oil filter on tight enough? again check out above it for signs of a leak. It may be the oil filter gasket or something simple.

    If your coolant and oil look normal than there probably is not a problem with the oil cooler.

    when removing the old filter it wouldnt come off.
    i had to use a tool to remove it (witch made holes in the filter)
    the new one is a purolator and i screwed it on tight. ill tighten it more.

    the coolant leak has been there for MONTHS.
    its not a large leak, just drips. ive only had to add g12 once, it never went much below the minimum mark line.

    i dont see anything above the hoses. seems like its coming out of that fat hose that goes to the oil filter.

    as far as the other leak in the back on the round ribbed part, i have no idea what it is or when it started happening.

    my car is loosing oil for some reason. a full dipstick two days ago to a half dipstick today is super odd.
    helppp

    The ribbed part is the transmission case. Can you go directly under the case and take pictures pointing the camera upwards like I have done on this thread:
    http://www.passatworld.com/forums/42...leak-pics.html

    This will help to compare if your leak is coming from the same area as mine. It may be a common problem with the TIP trannys.

    You probably still have OEM ATF so it is a different color than my ATF which was replaced by Indy 4 months ago. In any case my leak seems much worse than yours, so good luck.

    When you filled the oil, did you check the oil level on the dipstick before or after running the engine? If before only, then the difference in oil level is just the oil that is now in the filter.

    Depending on the filter, the ATQ holds 6.5-6.75 liters. You only put in 6 and the filter is full of air when installed. Once the filter fills, the level drops. That is why you have to check the oil level after running the car and letting it sit for several minutes for the oil to work it's way back down to the pan.

    i checked the oil this mornin before starting the car.
    i added another half quart to it before turning the car on.

    when i turned the car on it shook for a few seconds before warming up all the way.
    witch scared me.... any clue what that is?

    thats weird. mine has never needed more than 6 qts.
    maybe i never drained out the whole oil.
    im going to get under the car and look for some more leaks and snap some pictures.

    when i started the car this morning it shook for a few seconds while it was warming up.
    that was the 1st time it has ever done that.

    i also took a pic of the oil filter where the coolant leak is. and you can see
    some dry g12 (i think)

    shaking like a rough idle or shaking like a misfire? I have an 2003 atq, and from just time and mileage I'm pretty sure a clogged PCV system has caused a leak in the valve cover gaskets. I found this out by changing the spark plugs and finding a good amount of oil in 4/6 wells.

    I hadn't noticed any symptoms before I found out so your leak sounds more drastic. but if the oil is in the spark plug wells it could cause some misfiring until it all burns up and that can feel like the car is shaking.

    If its not a bad leak on the ground it could be getting burnt up through the exhaust (you could have some white smoke if its bad) but If your noticing a significant loss of oil its gotta be going somewhere.

    Unfortunately your tranny case pics do not show the region connecting to TC.

    Looking at your pics it is not clear whether you have leakage or not. Did you check your tranny fluid level?

    You didn't read the guide that was posted did you.

    TheMerk The factory-installed Pentosin ATF is gold colored. There is no transmission dipstick, the correct way to check fluid is outlined in this guide.
    You need to physically pump in fluid till it runs out to ensure it is full. It is impossible to know what level it is at unless you make it run out when its plump full.

    Read the link posted by merk. Wish it was as easy as in a BMW where the dipstick is right at the front of the engine. The person responsible for this design should be banned from the auto industry.

    im reading it right now. all it says is to feed atf through a hose under the car into the tranny pan.
    how the heck do you do that? do i need a special pump?
    also thats to fill the atf, to check the fluid level i need to buy new atf and force it up there and see it anything leaks?
    i might as well do a whole tranny fluid change.

    it doesnt say how to pump the fluid. just shows a pic of a white hose going into the tranny pan.

    anyone know how to actually pump the fluid up into the pan?

    If you go to an auto supply (or even garden supply) store you should find some small hand pumps. Some of the online vendors include one in their transmission service kits. How to? Stick one hose in the fill hole, the other in the ATF bottle, and squeeze the handle until fluid runs out. (GRIN)

    DO pay attention to the TaligentX article about having the vehicle level and the engine running.

    ok so plug out. hose in. and other end of hose into atf bottle. and buy a pump to force it out the bottle into the tranny pan?

    about the article, will running the transmission with the fluid drained out of it cause any damage to the tranny?

    im going to do a complete atf drain and fill and filter on friday/saturday.
    i hope i dont f*** up my car any more than it already is.

    Then there will be many engineers get slapped or banned from auto industry. Mind you, you won’t see the dipstick for ATF level on almost any new cars nowadays, including the BMW’s. Heck, BMW even banned the dipstick for engine oil; you get a warning message when oil level is low.

    Surprisingly I did spot an ATF dipstick on a new Madza 2 in dealer’s showroom.

    Maybe (GRIN). If it was me, I'd pump in as much as will go before starting the engine. Then once it's running, it should take another quart, quart-and-a-half.

    BEE5, depending on your budget, you may want to have someone look at this for you. Getting the car level, up on four jackstands, may be more trouble than it's worth. When my transmission pan gasket started leaking, I was referred by my VW dealer to a ZF transmission specialist. With a lift and the right tools, it's quick and easy to check the level - they didn't even charge me. (Actually replacing the gasket was another story).

    It can be difficult to tell where something is leaking; it spreads and drips all over. Maybe an experienced eye would do better.
