| ... with the atf if it is brown. It will still function, it's just showing it's age. Obviously if it is very dark brown it's an indication that it is old and will have lost more of it's lubricating properties than when it was red. I change mine roughly once a year......whatever the mileage......working on the principle that the cleaner it is the better it is going to function. In purely financial terms this might not make sense, but hey, a gallon of atf once a year is not going to break the bank. Flushing is simply a matter of draining off the old fluid, and ... | |||||
| RE: can a transmission be too cool? | 110Relevance | 5 years ago | DontKnowler | Submit Your Question HERE | |
| Check your existent atf thermostate first. An additional cooling fan installed on the main radiator will probably not do the desired job in your case, cause - the way most main radiators are - this main radiator does not cool the atf directly, BUT via the main engine coolant some small atf radiator (which is an integral part of the main one) is submersed into. You can not see this small one cause it is totally inside the main one. Such a multilevel system is designed this way on purpose in order to have vour atf heated to its operational temperature ASAP via the main engine coolant which in its turn gets heated by the engine (much sooner, than your atf would have gotten heated by internal friction happening in your transmission). So in order to super-cool your atf you would virtually have to super-cool your whole main radiator, meaning your whole main engine coolant, meaning also your whole engine, which is not an easy job and which is not good for the engine either - the engine does not enjoy too low coolant temperatures just like the transmission does not enjoy too low atf temperatures. So your proposed solution is a) hard to implement and therefore probably will not work as expected, and b) if it would, it would be bad for your car overall. I am sorry that this whole story may sound overly complicated, but it is the way things are, unfortunately. Even an additional atf cooler added in sequence with the one which is part of the main eradiator will not work well enough - cause in many cases this additional atf cooler, and the atf cooler hidden inside your main radiator, will be "battling" against each other, one atempting to cool the atf, while the other one is trying to warm it up, etc... Not a good solution. What I would do, is: 1) make sure your atf thermostate is OK - this is the main point; if yes, and if your atf still overheats - 2) I would install a separate large atf radiator in front of the main one (with or without additional fans), and route the whole atf flow via this new atf radiator, simply skipping and forgetting the atf-cooling main radiator circuitry. Imo this is technically the most correct solution - it will do the required atf cooling, avoiding excessive atf cooling, and your existent atf thermostate will make sure that it works optimally. The only thing this solution will not do - it will not have that accelerated atf heating via the heat of the main coolant, but this is the price you will have to pay for having an atf system which does not overheat even under heavy loads. Good luck! | |||||
| Which ATF should I buy | 37Relevance | 3 years ago | butchockkoi | Submit Your Question HERE | |
| Hello Scotty, Am a loyal follower of your videos. I'd like to ask if Castrol Multivehgicle atf Dexron VI be ok as an alternative atf for my old vehicle Chevrolet Optra 2004 1.8LS AT (with ZF4HP16 transmission). The manual requires ESSO LT 71141. However, such a fluid hard to find in our area in the Philippines. The last atf used in this vehicle is Castrol Multivehicle atf Dexron III but such atf is also now not being supplied by the distributor. They only supply now Dexron 6 Mercon LV. Would using the new Castrol atf be ok? Thank you in advance. Sincerely yours, ButchockKoi | |||||

| You should change atf regularly, … say, every 50k. It’s simple. Drive a car for a bit to warm up atf, park it, remove the dipstick, remove the drain plug and washer, drain the atf into a pan, install a new washer and the drain plug, tighten to 20 N-m, pour specified amount of atf through dipstick tube. atf: … you need to check it in your owners manual, but I think specked stuff is M-III or equivalent (Dexron III), … about 7.1 US qt, … approximate. Check level when atf is hot, adjust it as needed. Done. F.S. | |||||

| Bad mounts are bad news for the engine and transmission. That kind of jarring, over time, can damage both components. As for the fluid exchange: The exchange sounds like it was a "drop the pan" and "drain and fill" rather than a flush. So, apparently you did the right thing, in that regard. Tranny flushes, on the other hand, are "bad, bad, bad." Question: Was the atf fluid replaced with OEM fluid? Here's the link to the Mazda page, on recommended atf type for your vehicle: __ Most notably, it says the following (their caps) __ ALWAYS BE SURE TO USE THE CORRECT AUTOMATIC TRANSMISSION FLUID WHEN REPLACING atf. USING THE WRONG atf MAY CAUSE SHIFT QUALITY COMPLAINTS OR MAY EVEN DAMAGE THE TRANSMISSION.NOTE: atf M-V (TYPE M5) IS NOT THE SAME FLUID AS MERCON®V OR MERCON®LV . . . USING atf OTHER THAN atf M-V (TYPE M5) IN AUTOMATIC TRANSMISSIONS DESIGNED TO USE atf M-V (TYPE M5) MAY CAUSE SHIFT QUALITY COMPLAINTS. USING ANY OTHER atf OTHER THAN THE SPECIFIED atf IN AUTOMATIC TRANSMISSIONS MAY CAUSE TRANSMISSION DAMAGE. USING A GENERIC, MULTI-PURPOSE OR UNIVERSAL atf MAY CAUSE TRANSMISSION DAMAGE. __ So, what kind of atf fluid did you use? I'd start there. | |||||

| " we had an issue recently where engine oil was mixing with coolant fluid ... the transmission issues started afterwards"- Luckily I have no personal experience with oil and coolant mixing together. I can only confirm that this sounds like a severe engine-internal problem ranging from a blowing headgasket to cracks in the engine head or block. I can also confirm that in some rare and lucky cases you can get rid of this problem, at least temporarily, by using hacks like headgasket sealants added to your engine oil. Unless - unless it is just a leak in the oil-and-coolant heat exchanger. In Mercedes cars those are poorly built and tend to have oil leaks to the oitside, especially during cold weather, and this is a widely known issue I also used to have; however in rare cases those leaks can be exchanger-internal too, and in the latter case the result could be oil and coolant mixing together. This heat exchanger is inexpensive and not hard to replace even in DIY mode. Newer versions of this part are much better made than OEM ones.-This coolant-in-engine oil problem however sounds very engine-internal, and I have no idea how this could have affected your gearbox.-However unluckily for me I have excessive experience with coolant getting into my automatic gearbox = automatic transmission fluid = atf. I had this issue on my 30 yo Audi, however my w163 is technically prone to such issues as well, just as any other car with an integrated atf-and-coolant radiator is. In most such radiators, only two tiny O-rings separate the coolant and the atf circuit. Those O-rings are non-replaceable and are hidden deep inside the radiator internals, and once they lose elasticity (and with age they tend to do so), your coolant will start getting into your atf. You can easily tell that your atf has coolant within, because in this case it gets a very specific look - I hope "foamy" is the right word for it: with many tiny air bubbles within. Also, the atf level starts to increase (cause the inflowing coolant volume adds up to the atf volume). It is hard not to notice foam in the coolant visually, neither is it possible not to notice this when you drive cause this comes with heavy slippage of the friction disks when switching "upwards". But I did not mention this scenario earlier cause you wrote that you had your atf level (although incorrectly) checked by a mechanic, and even a bad mechanic would have noticed that an atf is foamy. So I hope this is not your scenario. Cause if it is, it is often the end of your transmission: the friction disks within the automatic gearbox consist of some sort of cardboard-like material, which is very friction-resistant when operated in atf, but which would fall apart almost instantaneously when operated in contact with water, coolant or similar other non-oily liquids. Particles which get into the atf as your friction disks start to degrade rapidly due to the latter getting in contact with coolant are also impossible not to notice in the atf when doing any level checks. | |||||

| Fluids degrade over time. In your case, you only drove 9,000 miles in 6 years (!!) while the average person usually drives 13,500 miles annually. Scotty recommends atf fluid changes 30,000-70,000 miles (in that range), so for most people driving 13,500 miles annually that is about every 2 to 6 years. I think it’s fair to change both the brake fluid and the atf now (just a simple drain and fill along with atf filter change if it has it). So many people neglect to change the atf fluid. See our sticky to become more familiar. | |||||
| Which ATF should I use in my 2010 Mercedes? | 52Relevance | 10 months ago | Jackoton416 | Submit Your Question HERE | |
| Greetings Ive been racking my head for weeks over whether to use Valvoline Max Life Multi-Vehicle to replace the atf on my 2010 Mercedes - Benz GLK 350, and i keep going back and forth. [ATF in question: ] My car requires atf spec 236.14 for its 722.9 transmission, and is the Red fluid for the 2010 Mercedes Benz GLK 350 made before June 2010, which i have confirmed via the VIN#. I currently have 130KM [81K miles] Valvoline Max Life Multi-Vehicle is listed as being recommened for MB 236.14, however, this atf is not listed one the offical MB website I want to use this atf in my car, but everyone i ask and the MB forum posts i read are all extreamly addament to ONLY USE MB approved atf, despite Valvoline stating they meet the MB 236.14 atf spec. They stress that it will somehow damage my transmission, over time at the very least. No car manufactuer makes their own atf, they source it out. And i hear these companies have to pay a fee to be on their "list" and Valvoline Max Life didn't pay to be on it. What is your opinion to using "non-MB approved" on my car. How would meeting the MB atf spec not be good enough? | |||||
| Answer to: Correct Automatic Transmission Fluid Level | 50Relevance | 5 years ago | DontKnowler | Submit Your Question HERE | |
| The atf fluid level is very much dependent on the fluid temperature. So if you are not controlling the fluid temperature precisely enough while you are doing your checks, you are not even theoretically close to any precise atf level measurements. Normally, what matters is the normal-hot level, which on all cars I know has to be measured at + 80 degrees Centigrade. The atf dipstick usually has special level markings (max-min) for such temperature, and even this temperature itself is written on some dipsticks. Some dipsticks also have level markings for 20 degrees Centigrade, but those are not so relevant: at any temperature other than + 80 degrees Centigrade, the atf level just has to be somewhere on the dipstick - does not really matter where. The check is done when your car is standing on a level surface, with engine running- You may also want to switch between different gears shortly before you do your measurements, but I am not sure if this is a must for all gearboxes or just for some of them. Important is that you "catch" the correct temperature with, say, +- 1 degree precision. There are different ways of monitoring the atf temperature - from reading indications smart gearboxes provide via diagnostic scanners to just measuring the atf oil pan temperature with IR handheld measuring devices. But if you want an exact measurement / level setting, you have to make sure you do it at the prescribed temperature. Just "drive your car for 15 minutes" is not precise enough. Most important of all is, that you generally set yout atf level when hot, and not when cold - the atf volume / level setting error would otherwise be dramatic. But as long as you are setting it when hot, it actually makes little practical sense to be overly pedantic about the atf level: in the automatic gearboxes I saw from the inside, +- 0,5 liter deviations do not do any harm at all - the gearboxes are made in such a way that they cannot even notice such difference. Otherwise they would not be able to properly work provided those huge atf level fluctuations between cold and hot. | |||||
